Video Transcript for Optronics Trailer Lights RVST50 Review

Today we are going to review Part Number RVST50. This is the Optronics Camping Travel Trailer Stop Turn and Tail Light. This is a multi-function stop turn and tail light on a white mounting bracket. This is a molded plastic housing with a durable lens which will provide all weather protection against corrosion. This light does feature a replaceable snap on lens and an easy to replace bulb. The Bulb Number would be a 2057.

The mounting surface or the mounting bracket on the back has four mounting holes, one in each corner and the distance between those holes is seven inches and this way would be 3 1/8 inches. It does have a three-wire design which is the one wide wire for the ground and then the two power lead wires for the tail lights and the other one is for the stop and turn signal. This tail light is weather and corrosion resistant. I am going to give you a few measurements on this light; the overall length of the light will be 8 5/8 inches. The width will be 4 5/8 and the depth of the light will be 2 1/16 inches.

Now, what Im going to do is hook up a power supply to the light to give you an idea of the brightness of the light. That would be the tail light. That would be the stop and turn brightness. Now what I am going to do is turn out the overhead light to give you an idea what the brightness of the light would be in the dark. So again, this is the brightness of the tail light and then when we apply the stop or the turn signal that would be the brightness there.

That should do it for Part Number RVST50.

Right product, right price. Easy install, perfect fit. I got both left snd right tail lights, including shipping for less than a single light at Camper's Inn. The only suggestion I can make is they should include some form of soft gasket material to prevent water from getting behind the and possibly entering the hole in the trailer where the wires come through. I used a general purpose weather stripping putty for this purpose but a form fitting gasket would be a nice improvement. etrailer.com, I'll be Baaack. 142945

Great service. Installed the new lamps in a couple of hours with few issues. Only concern I have is with what appear to be rather fragile looking "clips" that hold the red lens cap onto the white body. My previous experience with this design (different product) has resulted in broken clips, so I filed the tabs on the "clips" down a bit to hopefully make the removal of the lens easier. 138429


Lights are working perfectly. I just know that I will have to be very careful when I remove a lens cover so as to not break off a plastic tab. But, all in all, Im very pleased.

This is an exact replacement for the tail lights on my 6X12 enclosed trailer. I always research pricing and quality before I purchase and this was the best buy I found. The delivery was quick - @ 3 business days from order - and the quality meets my expectations. I will definitely bookmark this site for future purchases. 92382


No problems whatsoever! Lights still working like new with no corrosion or other issues. Thanks for the follow-up. You guys are awesome!

The product was great looked great and should be a direct replacement for what was on the trailer originally. One word of caution don't cheap out on the shipping. I got the cheapest shipping and the way it worked is UPS would deliver it to the closest USPS post office then USPS would take over and deliver to my house. Well I have a small rural post office that's only open 4 hours a day and UPS tried to get it to my post office twice but on both occasions my post office was closed, I call UPS and was told if the third attempt failed that I would have to drive to the nearest UPS distribution center an hour away to pick up my package or it would be sent back. Well the 3rd attempt UPS managed to get to my post office before they closed, but just barely. Everything about the product I got from etrailer was excellent. The Shipping companies seem to have had a steady decline in their customer service. 107615

These trailer lights are of very good quality, I like the socket the bulb fits into and were an excellent price. They were shipped to me super, super fast. I can not install them as yet because we are still in winter here. I have ordered from here before and I am a very happy customer. Thank You. 128270

I have heard and read a lot about etrailer.com and did not believe that they were that good. I order this product for my camper and did the ground shipping, it said 4 or 5 day delivery time, and I actually got it a day early. I installed it the next day in 5 minutes, the item looks just like the other one I order last year from another company, the only different was that etrailer product had the same color wiring as my camper was. and the other company product was WAY off which made installing it a BIG pain in the butt. Also etrailer email me to see if I was happy with their product and the other company didn't give a dam if I was happy, they already got my money. I like this type of service and is already planning to purchase more from etrailer.com. They are that good !! Thank-you!!! 145479

What can I say... these lights are "replacements" and not the OEM lights, but they are higher quality and better looking than the originals. Etrailer shipped them right out... they were shipped out the day I ordered them and on my doorstep 2 days later. When I took the originals off, I noticed they were in place by rivets, and I was nervous about drilling them out of my ABS trailer. However, it was no problem at all, and I'm so glad I took on this project. I replaced 11 lights and both brake lights, and it has given my 1996 trailer a much needed facelift. The old lights were tired, and the bases were black. The new lights have white bases and they they are MUCH brighter and more vibrant. The lenses fit snug. Oh, and the price was incredible. Great transaction. 78423

I was searching for some replacement tail lights for my vintage 76' Scotty Sportsman, these turned out to be a perfect fit (size) They do feel alittle fragile but they seem to be more than tough enough once installed. I will definitely be using E-Trailer again for future purchases. My next project is to replace the teardrop running lights on top. 146727

After working on the old lights on my camper numerous times just prior to leaving on a trip and while traveling, I decided it was time to replace all of the lights. I purchased two new tail/brake lights, and four new side markers. The total price including shipping was just over $28 (I should have done this a long time ago). The lights arrived within 3 days of being ordered, and I was able to install them fairly quickly. I am so happy that I now have all six lights working perfectly, and shouldn't have to worry about them for a long time. 16914

I ordered replacement taillights for my camper trailer after mine were smashed by careless children playing a game that involved bouncing a heavy ball off the trailer wall. This is the second time I have ordered from etrailer.com and will continue to do so for all my trailer part needs. I give customer service an A+, ease of ordering and the prices also get an A+. The package arrived safe and secure two days before I expected it. The lights I received were an exact match to the ones broken on my trailer. Way to go etrailer.com! 126456

This product is exactly as presented. I installed this product on my Flagstaff Pop-up camper and it worked perfectly. The mounting holes and wire colors were an axact patch to replace the original equipment. The price was about 50% of the originals and is a superior product in my opinion. I removed the cover lens and applied a coat of chrome metallic paint to the lamp mounting surface and this gave a reflective and produced a brighter glow. This is a small improvement to a near perfect product. 51355

I replaced the tail lights on my travel trailer with the Optronics Trailer Lights - RVST50 & RVST51 for half the price of other name brand lights. The installation was easy and the lights worked great. They are bright and easy to see, both day and night. My only complaint is that the lens cover may be a little too tight of a fit. I was afraid I was going to crack the lens pressing it onto the base but it snapped into place without any problem. I suppose that is a good thing after all. 211030

Very prompt service, excellent shipping and communication from the sales team. I ordered multiple items at once and the staff bundled them all in one shipment and had them shipped the same day I ordered. Each product was exactly what I needed and as research will show, they have the best prices on the web. Couple that with free shipping and it's impossible to not recommend this company to all.

My Coleman pop up is 27 years old and the old lights have been repaired with red tape more than once. The new lights arrived quickly and are as good of quality as the originals or better. The mounting holes did not line up exactly as the originals, but drilling new holes through the aluminum skin of the camper was not a problem. I used pop rivets to mount the new lights. I am very pleased with the results. $15 for two lights and shipping. Why didn't I do this years ago? 154352

These were easy to install as replacements on my pop-up. They are much brighter than the old ones. And again the shipping from etrailer was faster than quoted, arriving one day sooner which was good because we were leaving on a trip the day they were scheduled to arrive. 136777

Installed today on my Jayco popup. I used the old harness instead of replacing all the wiring, then replaced the Jayco 6 prong with a four prong plug. The lights look really good, and would be hard pressed to tell they are not OEM. 137001

"Filled the Bill" Simple, but effective design; installed easily. This was a replacement for an earlier-design Optronics model, to cosmetically match the license plate holder version (left side) I had to replace. The only precaution I would recommend is to not be as ham-fisted as I was, and break off a plastic tab of the license plate holder version like I did on the original one, while trying to get the temporary tags off. 4694

Replaced old original tail lights on 91 Dutchmen TT. Much brighter and I don't have to hit the lights before each trip to make them work. Easy to install, the only problem I had was these mounting hole didn't match up with original holes so I had to seal old holes and make new ones. Didn't come with directions so you'll need to remember or label the wires as they come off old lights. 200028

Can't believe how fast I received package. Now that the snow melted of course it's been raining so hopefully I can slap these on our (new to us) pop-up camper SOON !!!

Bought these to replace broken lights on my 95 Coleman Roanoke. Very well built, and easy to install. They are not a direct replacement, as the mounting holes did not line up.

We lost the red lens on the OEM lights on our Rockwood Mini Lite and I couldn't locate a replacement lens, so I ordered these lights to completely replace the existing ones.

I bought these thinking that I would have to re-mount the entire unit to both lights on the rear of a pop-up camper.

Work great just unscrewed the old light cut the wires used three butt connectors to connect the new light. Removed the lens screwed the new light on and popped the lens back on. Same as the oem light I had. Screwdriver, wire cutters/strippers and three wire connectors is all you need. 134150

by: Tom10/25/2014

Be sure and check the wiring before installation. I assumed the taillight's black wire would go to the trailer's brown wire and the taillight's green wire would go to the trailer's green or yellow wire - nope, I got it backwards. Otherwise, easy to install and works fine. 157911

  • The Camping Travel Trailer Stop, Turn and Tail Light, # RVST50, has a total of 3 wires. The white wire is the ground and needs to be connected to a clean and corrosion free metal surface.

  • Trailer Lights Go Out When Running Lights are On and Brakes Applied
  • The reason this is occurring at night and not during the day is because during the day you are not using the running lights. There are a couple of possibilities here. First, check the main trailer connector grounds on the vehicle and trailer and make sure they are attached to clean and corrosion free bare metal surfaces. Also do the same for the tail lights on the trailer. A bad ground can cause this issue. Ground problems show up when there is more load on a system. When the running...

  • Running Lights Not Working But All Other Lights Are on Optronics Trailer Tail Light # RVST50
  • Since you have already looked at the ground wire for tail light # RVST50 then it is probably not an issue with this ground. The wiring on this light should be as follows: White wire: ground Green wire: tail light Black wire: stop and turn light Disconnect the trailer and use a circuit tester like # 3808 to test the 4-Way on the vehicle. If the running light circuit is working there then you know the issue is on the trailer. If it is not working, then you know there is a problem...

  • Replacement Tail Light Assembly for 1988 Coleman Chesapeake Pop-Up
  • The Optronics # RVST55 would be a good replacement taillight, like your existing lamp it is a 4 wire/ 2 bulb taillight. If you went with a single bulb, you would lose the reverse light function. If you would prefer a lamp that only provided stop/turn/running light functions, the Optronics # RVST50 would be a good choice. The lamp uses three wires, white for ground, green for running light and black for turn/stop light. Either Optronics lamp would be a pretty close replacement for...

  • Troubleshooting 1973 Road Ranger Travel Trailer Turn and Stop Lights Not Working with Tail Lights On
  • It sounds as if you have a ground connection issue, or a short on the tail light circuit on the trailer. Most likely it is a bad ground that will need to be found. The bad ground shows up when the tail lights are turned on because that is when the highest amount of amperage draw is placed on the wiring. I would start with the trailer connector on the truck and trailer. Open them up and make sure there is no white or green corrosion causing an issue inside the connectors. If so clean...

  • Troubleshooting Blinker Lights on 1977 Road Ranger Camper
  • You should only have one wire going to the turn/stop signal connection and one wire going to the taillight connection on each side of the trailer. Left side turn/stop wire is yellow, Right side turn/stop wire is green, taillight wire is brown. White wires should be grounded securely to a clean metal surface. Make sure the trailer and truck grounds are good too. If the problem is still there check the connector from the vehicle. One wire broken or shorted can cause many...

  • Replacement Tail Light for 1994 Coachman Catalina Trailer
  • I was able to find photos of the rectangular tail lights included on the 1994 Coachman Catalina but I could not confirm a manufacturer name. However, if the dimensions of the light you referenced, Optronics Trailer Light # RVST50, match yours then this 3-function light should work fine as a replacement. This item works as an exact replacement for a Wesbar 3621 and Peterson 2533W. This light measures 8-5/8 L x 4-5/8 W x 2-1/16 D and it mounts using bracket # RV50BK. The bracket mounts...

  • Camper Has Separate Brake and Turn Signal Lights But Truck Has Combined System 4-Way Flat
  • Typical trailers have what is called a combined system. This means that the brake lights and turn signals on each side are on the same circuit and the running lights are on their own circuit. Your set up sounds like a separate system where the brakes have their own circuit, turn signals have their own circuits and the tail lights have their own circuit. Your truck has a 4-Way flat which means that it is set up for a combined system. There are 2 ways to handle this problem: 1) You...

  • Running Lights Not Working on an H & H Trailer with 5 Wire Trailer Connector
  • First, use a circuit tester like # 3808 if needed to test the brown wire to make sure it is functioning properly at the vehicle side connector. If not then you will need to troubleshoot the vehicle. On light # RVST50 the green wire is the running light circuit and the black wire is brake light/turn signal. Make sure the main trailer connecter is grounded to a clean and corrosion free bare metal surface. Do the same for the lights. If the trailer has an aluminum frame, grounding the...

  • How to Wire up a New Trailer Connector on a 2013 Sundance Travel Trailer
  • To eliminate all the guesswork involved in rewiring a trailer connector to your trailer I would recommend you make a jumper wire from a 12 volt battery (a vehicle battery would work great for this) and run 12 volts to each of the wires from your trailer to see for certain what circuit that wire carries. It looks like the wires from your new connector are the standard wire colors but just in case I attached a photo of how a trailer 7-way should get wired. I also attached an FAQ on...

  • Troubleshooting Wiring Problem on 1977 Travel Trailer
  • The first thing you'll want to do is get the trailer connector on the truck operational again. The procedure for this will depend largely on the year, make and model of the truck. If the truck is newer, it would likely have a factory tow package that uses relays to control and fuses to protect the towing circuits. When you checked the function of the connector on the truck, are all the features dead (right turn/brake, left turn/brake and running light) or are some working? If some are...

  • Why Will Fuse Blow When Brakes or Turn Signal is Applied on 2008 Ford F-250 Towing a Trailer
  • It sounds as if you have a ground connection issue, or a short on the tail light circuit on the trailer. Most likely it is a bad ground that will need to be found. The bad ground shows up when the tail lights are turned on and the brake or blinker is used because that is when the highest amount of amperage draw is placed on the wiring. I would start with the trailer connector on the truck and trailer. Open them up and make sure there is no white or green corrosion causing an issue inside...

  • New Trailer Lights have 3 Wires but Old Trailer Lights have 4 Wires
  • You will need to determine what the functions of the wires are on the existing lights using a circuit tester like # 3808. Have the trailer connected to a vehicle and have someone run through the light functions to determine what the wire functions are. Trailer light # RVST50 has a white ground wire, green for running lights, and black for brake lights and turn signals. On your trailer wiring, the white is probably the ground if it was attached to the frame. The brown wire is most likely...

  • Running Lights Not Working on 1964 Aloha Travel Trailer
  • You certainly should be able to access the running lamp circuit behind each of the lamps. Finding the other end to tie into the running lamp circuit from the trailer connector might be a challenge. If need be, you might just run a new running lamp circuit from the trailer connector to feed the running lamps. I have linked you to our Trailer Wiring FAQ article, which you might find helpful.

  • Troubleshooting Right Turn and Brake Light Not Working on 1979 Prowler Camper
  • Since you recently installed the Optronics Travel Trailer Lights, # RVST50 and # RVST51, I would first recommend checking the ground and wire connections from the light to the trailer. If the ground is not connected to a clean, bare metal surface or the wire connections are loose or pinched, then you could see issues. If the light connections look fine, then I would recommend starting at the vehicle side trailer connector and working back toward the trailer. Take a look at the trailer...

  • How Does Camping Travel Trailer Stop, Turn and Tail Light, # RVST51, Mount to the Trailer
  • To mount the Camping Travel Trailer Stop, Turn and Tail Light, # RVST51, you will need 4 screws for the mounting holes on the back of the light assembly. This light comes with a license plate bracket and light. The light for the other side of the trailer is Camping Travel Trailer Stop, Turn and Tail Light, # RVST50. If you can give me the serial/model number and manufacturer of your existing light assembly, I can find if there is an exact replacement.

  • How to Properly Ground Trailer Marker and Taillights
  • Each lamp needs to be grounded either through its mounting studs being in direct contact with the trailer frame or by having a jumper wire ran from the lamp to the trailer frame. Ground the trailer connector at the front of the trailer, which will use the trailer frame as a ground wire. This method is the most simple and effective. You could run a ground loop, but if everything's properly grounded, it won't be necessary. I'll link you to our FAQ article on trailer wiring.

  • How Does the Optronics Light # RVST50 Wire to a Trailer
  • On the Optronics Light # RVST50 that you referenced the white wire will need to be grounded, the green wire will need to be run to the running light circuit and the black wire to the stop/turn circuit. Assuming the wiring you listed for where you plan to install this light follows the standard taillight color codes the white wires would match each other, the green of the light runs to the brown of your trailer, and the black of the light would run to the green of your trailer. If...

  • What Gauge Wire Should be Used to Wire 8 Marker Lights, Incandescent or LED
  • First, LED lights do draw a fraction of the amperage compared to incandescent lights. But going with either 16 gauge or 14 gauge wire would work. I would say if you use incandescent bulbs then 14 would be the better option and 16 gauge for LED lights.

  • 1996 Palomino Trailer Wiring Troubleshooting
  • Make sure that the trailer side connector are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt the ground. Running jumper wires from the...

  • The Main Reason for Nearly All Trailer Wiring Problems
  • Rewiring a travel trailer like yours would be pretty challenging as you will need to most likely remove interior walls to access the wiring. Since it would be much easier to check the grounds first (as that is most likely the actual problem) I recommend you start there. Nearly all trailer wiring issues are ground related. Try finding a better ground for the light assemblies on your trailer to see if the issues you are having go away. Some assemblies ground through their mounting hardware....
