Video Transcript for Optronics Trailer Lights - Tail Lights - STL003RFLB Review

Today we're going to be taking a look at part number STL003RFLB. This is the Optronics round LED trailer light. It's going to feature one LED. It's going to serve as your brake light, turn signal and taillight. It's going to feature a sealed waterproof housing, as well as a lens unit. Here on the back side, you're going to notice that it has the connection point for a three wire pigtail.

These tabs that come off of here are actually locking tabs, so once that connection is in there, that bracket or that housing on the back of the plug is going to lock in these brackets and that's just a safety feature, as well as a feature that's designed to prevent theft. It's going to clip on either side of the plug for a nice, tight, secure fit. This uses surface mount technology, which is designed to protect the LED from shock and vibration. The diode is actually mounted directly onto a circuit board instead of through a hole. It's going to feature a long lasting LED. It's going to be a great replacement for an incandescent light.

LED's are going to last 50 times longer, you don't have to worry about replacing bulbs. You don't have to worry about brittle filaments and LED's are going to be more efficient, so they're going to provide brighter light with less power output. It's going to feature a sturdy poly-carbonate lens, as well as a housing. This is Department of Transportation compliant, so it meets FMVSS 108 requirements and CMVSS requirements for automotive lighting. We'll take a look at the overall dimensions real quick. It's going to give us an overall diameter of 5 1/2 inches.

Now the actual light itself, or that lens, looks like it's going to be about 4 1/4 of an inch. The depth of this unit is going to be about 2 inches. You can see here that this is going to be a flange mount design, so it has that flange that goes around the housing. That's going to have three mount holes. If we take a measurement, the distance that we have center on center between each hole. That's going to measure 4 1/4 of an inch, and that measurement is going to be the same no matter how you measure, center on center between all the different holes.

So you have three different holes, center on center 4 1/4 is going to be the separation. Optronics is going to put a lifetime warranty on the LED. Again, you have the three prong connection here at the back. A couple different options that you have, it does not include the plug that you need, so you can find that here at etrailer.com. It is going to be sold separately, part number A45PB is going to be the one I'm using for our demonstration today, or you can get a right angled plug, with part number A47PB. I'm going to go and hook this up to our external power source, that way you can see what it's going to look like with power running to it. Simply just take our plug, run it through the guides there, that is locking tabs, straight into the connections. It's going to snap into place. You can see there that once that is fully connected, creates a nice tight seal around those connection points, so nothing is going to get in there and do any damage. This is going to be the taillight function. Again, this is just one LED. When we apply our brakes, you can see how that brightens up for a brighter signal output. It's also going to do that when we activate our turn signal. That's going to do it for today's review of part number STL003RFLB, this is the Optronics round LED trailer light. .

Used these lights to upgrade to LED on my triple Axel equipment trailer. Lights are nice and bright. Would have given 5 stars except that since I have ordered these lights I have been bombarded with trailer light advertisements that just won't quit.

Bought to replace existing weathered lights in a heavy trailer. Looked the same as depicted but my frame around lens was metal ,not plastic like the ones I received. I will use them, exact fit, but I doubt they will take the abuse the original did over the years

Great value. Perfect size. Easy to install. Dimensions were spot on. Installed on the back of an old Jeep. Only complaint is that the retention clips on the back are a little fragile, at least in the cold. A few snapped off but the plugs seem to hold well regardless.

Review from a similar ONE in Trailer Lights


Product and service brilliant. One the big things in service have been sorted, eg. good product, value for money (not cheapest) delivered in good condition in a predicted timeframe, it's the little things like an email with tracking url that has ALL the information you need... WITHOUT HAVE TO TYPE IN A TRACKING NUMBER , NAME, ZIP ETC. And same with review, click on a url in an email and enter your comments with pictures .....SIMPLE. so many other companies just make these types of things too complicated and onerous for the customer to provide feedback. Also each person in the process is named! Brilliant, personal and just nice. I wish you guys were responsible for all of my transactions for all the things I buy online. Thank you to all of you at etrailer fantastic job.

Review from a similar ONE in Trailer Lights


Terrific upgrade in my opinion. The installation was pretty easy for me. The light is slightly smaller than the original and I have the corrugated sheet metal siding I did not experience any led hyper flash with this light. I was slightly concerned about this after seeing videos of people changing to led light bulbs on the tow vehicle. This light was plug and play. 4 stars because the manufacturer did not provide a wiring diagram :( I don’t feel you should guess what wire goes where. The least they could do is tell you what they (the manufacturer) wired for ground. In my case, the white was ground, same as my trailer wiring. However I needed to connect green to black to get my turn signal to work. Your situation may be different. Would I buy it again? At this time, yes. I’m hoping this light outlasts my usage of this travel trailer- which should be for many years.

So, I rewired my trailer to not have any wiring connections underwater during a launch operation. To accomplish this, I placed the "etrailer" tail lights and brackets on existing guideposts, then using two "shielded electrical extension cords" I routed them from the tail lights to the trailer hitch plug-in connector.

LED light was a perfect fit and easy install. In attached photo LED is on right and incandescent on left in photo (daylight photo was darkened to show lights better). The photo doesn't show it clearly, but both my wife and I believe it is slightly brighter than the incandescent bulb. I have had some trouble in the past with the incandescent bulb not making contact. This should not be a problem with the LED bulb.

My Son picked up the trailer today to use and the tail lights were working fine. Very bright.

I just got a new tracker boat & trailer and I did not notice the taillight light was cracked (it still worked). This light cost more then most, but the quality is evident immediately and a perfect match from the old one. It was a 5 min. replacement.

Review from a similar ONE in Trailer Lights


So i have a 94 Jayco pop up that one of the tail lights got smashed. The company that made those lights is no longer around. After some searching on etrailer.com I decided on these LED lights. Price was right. My only real complaint is that these lights come with nothing. No screws, no instructions, no seals. So when I pulled my old lights and found that they had 4 wires and these lights had 3, time to do some research. None of the wire colors matched up. Not the trailer wires, not the old lights etc. On etrailer there is a video describing the lights in detail. Watch it. He goes over what color wire does what on the new light. I hooked the trailer up to the car to figure out the old lights wiring scheme. I was able to figure it out from there, though you cannot wire both sides up the same, if you do when you put the turn singles on they both flash. I had to leave the brake light wire disconnected on one side. Brake lights still work without it. I used plumbers putty to create a seal. That is also what they used on the originals and I used the original screws to make new holes and mount the lights. All in all it worked out but instructions would have been greatly appreciated!. I am sure etrailer would have jumped in to assist if I asked but it was not needed. Pictures posted. Old lights on bumper for reference.

Review from a similar ONE in Trailer Lights


I ordered both the RVSTLB0060 and the RVSTLB0061. My only disappointment with the RVSTLB0061 was the LED module was not attached to the frame like the RVSTLB0060. Luckily, I had two small sheet metal screws I could use to secure the LED to the frame mount. My installation was on a 2016 Rockwood A212HW. The OEM lights were the Optronics incandescent version. RVSTLB0060/61 are direct replacements except for the odd (offset) drill pattern used during factory assembly (they did not use all the Optronic predrilled holes). OEM mounting screws were reused but I added a bead of glue to the threads to help secure over time. Note the factory uses a good bit of RTV silicon on the top portion of the light frame to help hold in place and fit the slight curve of the body.

Much better than the trailer's original tail lights which occasionally did not work because of a poor connection inside the light housing. These are brighter with an improved connection to the harness.

Review from a similar ONE in Trailer Lights


I have used many of the Optronics LED lights. Good brightness, good prices, seem fairly durable. These were going on the back corners of a hitch cargo carrier. Just be aware that this is called a surface mount, but has the wires out the back. You will need a hole in the panel to route wires, or a spacer to lift off the surface. I wanted a true surface mount with wires out the side of the light. I made it work. No issues with the light, just need the catalog listing edited to be clear.

I like these LED taillights for the "older" look I have with my 1958 CJ-6 Jeep. They are not blind the person behind you bright, but they are a great replacement for old incandescent type taillights, with less amp draw and long life span. I would recommend them for an old style build with new LED technology.

  • Comparing Optronics # ST40RB and Optronics # STL003RFLB Trailer Lights
    Aside from the Optronics # ST40RB having an incandescent bulb and the Optronics # STL003RFLB being LED the only other big difference is that the first part grounds through the mounting hardware while the LED version grounds through a wire. This is why one unit has 2 wires and the other has 3. We have 2 pigtail options for the LED verison for you to use. Part # A45PB has the wires coming straight out of the plug while part # A47PB has a right angle for tight spacing where your lights...

  • 4 Inch Diameter Trailer Tail Light Options
    We do have a number of options for trailer tail lights that are 4 inches in diameter, although the standard for these lights is a 3-wire system: ground, turn signal, and tail light. Your lights may have grounded through the mounting hardware, but these lights will use a wire for that. The options I recommend are LED because they are going to last much, much longer and have a lesser power draw than incandescent lights - Peterson LumenX LED Trailer Tail Light - Stop, Tail, Turn # M824R-7...
