    Video Transcript for Optronics Trailer Lights ST8RB Review

    Today we are going to review part number ST8RB. This is the Optronics trailer stop, turn and taillight. This is a six function light for the right hand side of the trailer. This multifunction stop, turn and taillight. This will serve six functions for trailer that are less than 80 inches wide of the stop, turn, the tail, a rear reflex, a side marker and a side reflex. This is corrosion resistant lights.

    The molded plastic housing and durable lens will provide all-weather protection against corrosion. The light features a screw down replaceable lens and easy to place incandescent bulbs. The part number for the bulb that is using this is 1157. The light socket is shock proof so it guarantees long bulb life. The light is a universal mount with two studs on the back and these stud are on a two-inch center and this light is grounded through the mounting studs so when this is installed your grounding point would be the studs.

    A few dimensions on the slide. The overall length from side marker to edge will be 5-17/64. The depth will be 2-7/8 and then on the light itself will be 4-9/16 by 4-9/16. And this uses on the back, it will use the quick connect wiring and what you would do there is basically just strip your wire and insert it into the hole and it will hold in there and then to release it theres a little hole right under it. You just push like a paper clip in there and you can remove the wire.

    So I have a power supply here. Im going to try to give you an idea of the brightness of here and it is marked on the back, the color and the function of that. So I put in the brown for the taillights. So if I use the white and ground it to the stud, that will give you the taillight brightness and then I a green wire which will be for our stop and turn. I push that in and again I ground it.

    Then this will give you the brightness of the stop and turn. Then what Im going to go ahead and do is turn off the overhead lights and then I will show you the brightness. This will be the taillight, and that will be the stop and turn and that should do it for part number ST8RB.

    This multi-function light fixture replaced the one that came with the new 18-ft. standard car hauler I bought from the Carson Trailer Co. located in Gardena, CA near Los Angeles in 2008. The trailer's mandatory lighting and warning devices consisted of the same fixture as shown. It's nearly unbelievable that this fixture can be manufactured, even in China, and peddled in the U.S. for $5.50! plus sales tax and shipping costs of course. I opened the fixture to discover the failure point and found that the ground wire inside the fixture had broken loose from its soldered position due to negligent soldering technique. I'm keeping it as a reserve unit. Etrailer performed as promised. US mail delivery was slow since their trucks do not go on a private road. The unit sat in a communal mailbox about a mile away for several days. Suggest that the seller use UPS, FedEx, etc depending on cost and how fast you need the unit. The 4 small screws that hold the red lens onto the plastic housing look pretty when new. But they will rust badly exposed to the outdoor elements. Also, threading multi-wire conductors into the hookup retention holes is a sweat. I finally had to install 16 gauge solid-wire conductors for stiffness in order to get them into the retention holes. Unless you have 3 hands it is very frustrating to use a paper clip to pry open the retention slots via the holes. The way the fixture is designed is very unique. Ken 154268

    I bought this because I broke one just like it on a neighbor's trailer. It is the same as the original and fit perfectly. 122016

    The lights arrived in a timely fashion at a very good price. Upon opening the box, I was initially puzzled by the lack of wiring pigtails. Darn, I guess I need to order a plug; OK, it's been a long time since I changed my trailer lights. Oh, but after a little research, such was not so. The trailer wires simply pressed into the rear of the light housing and self tapped - how simple. Maybe, a sliver of paper instructions enclosed would have been in order. Maybe not..... Overall, I am most pleased with my dealings with eTrailer. 335670

    I am 72 and have never done this before. It couldn't have been any easier. Even though this was a small item, the service you gave me couldn't have been better. The light came today and I went right out and put it on. [I backed my car into the original one.] You made this so easy for me to order. The girl on the phone was easy to understand, and very helpful. Also, I did look at all the info you give on your sight. Why would anybody buy from anyone else. Thanks for the great service. Sincerely, Pat 107152

    Item arrived quickly and was well packaged. It is an easy install, simply strip the end of your trailer wires and feed them into the appropriately labeled spring contact (Stop / Turn or Tail ) that will automatically seat the wire in place. Removal of wire is done by using something like a toothpick to push on the spring contact thru a small hole below the wire to relieve tension and slip the wire back out. Like some speaker connections. Both lights worked first time. 143423

    The trailer lights I received were very good quality and an exceptional value. I am installing them on a motorcycle sidecar that I fabricated for my motorcycle. The tail lamps sold by Harley-Davidson range in cost from $79 to $130 each and do not offer as much functionality (don't provide a side marker lamp feature) as the e-trailer lights. The H-D lamps also require a special wire harness at another high cost. I am extremely satisfied with my purchase. 98701

    Could not believe how inexpensive part was, figured have problems else where,,,but they shipped faster than any other store, great follow up (I have had 4 emails confirming order and checking in!) and exactly what I needed. I had problems with other companies that week, and etrailer came through, and proved they truly believe in customer service! BTW this is a $5.95 part, and treated this like a big order! 127652

    I purchased these lights to replace a pair of weathered, beat up lights on my cargo trailer. Everything was just as advertised and they were a snap to install. The quality is good. The lights are plenty bright and they have stood up to the harsh Arizona sun and heat extremely well. Paint faded just a bit, but they still look nice. I'll be back to etrailer again if I ever need to replace them. 349448

    I ordered two trailer lights for my utility trailer. The lights I received and your prompt service were both outstanding! I would really appreciated the follow-up emails telling me the process of when my order was shipped I when I would be receiving my order. You guys exceeded my expectations. I highly recommend your company and look forward to doing business with you again in the future. 48475

    Quality product, easy to replace, and has excellent visibility when lit. I break these periodically because of the harsh terrain and poor roads where I frequently use my 16 ft. trailer and these work as a quick, economical replacement for trailer taillights exposed to regular use in these conditions. Sooner or later most trailers will suffer breakage of taillights with regular use. 134205



    - ST8RB

    by: Gary Geddie10/11/2012


    The lights arrived in perfect condition and in a timely manner. However, I assumed wrongly that there would be pigtail wires already soldered to the lights so I could attach the existing trailer wires with connectors without having to disassemble the light. I'm afraid I might have to return the lights I received and reorder the lights described above. 56993

    The light fit perfectly but I'm having trouble with the bulb staying in place. It wants to slowly rotate when driving down bumpy roads and I end up taking the lens off and manually turning the bulb slightly to get it working again. It's not bad enough to send back I just have to figure out a way to keep it from turning. 443166

    Liked the way the wires attached to back, but no protection from outdoor elements, filled wire attachment area with RTV after wires pushed in. The Ground is one of the attachment studs, nothing to tell you that. So if you attach to a plastic fender you need to run a ground wire to one of the studs. 31100

    Quality light, fast shipping, easy to install. I had not seen the quick wiring prior to these and it was very simple to strip the wire and insert into the light.

    they work good. but im not crazy about the wiring connection. the wires just push into the housing, their is no plug or sealing of the connection of any kind. once its on the trailer, I am going to coat the connection with rtv. but outer than that, they work good. 248915

    A good inexpensive incandescent stop/turn/tail light with extra bulb that illuminates sire marker. I did not need a license light function, so I used 2 of these lamps, & easily mounted one upside down on the left side of the trailer. Easy stab wiring. 426676

    This unit was physically identical to the original installed on my trailer which made installation a snap. Wiring on both units was via spring clamps on the bare, stripped wire. Function so far has been fine and the price was right. 15650

    Quite happy. Ordered trailer lights. However the supplied wireing was to short end after installation came apart requiering takedown and 're do If your supplier could add 1 or 2 inches to the wires would make a great difference 355650

    Great product, fast delivery, I really like the "tracking map" as you are the first people I have seen use it. The light bolted right up to the mating holes on the trailer, and even came with bulbs. What's not to like? 210773

    The light itself is great. I was expecting some leader wire and some epoxy or something to hold them in place though. One things for sure though, when I back the trailer into a pole next time I'll be buying this again. 166665

    Loved the product and it shipped quickly and safely. Used it as a replacement for a used trailer I purchased. Worked out great and would purchase it again if I needed another one. 359243

    • Utility Trailer Light Wiring Diagram and Required Parts
    • I have attached two basic trailer light wiring diagrams of utility trailers for you to check out. The difference between the two diagrams is the type of wiring harness that is being used. Diagram 1 shows a traditional wiring layout with jumper wires to provide running light functions for both sides of the trailer and Diagram 2 shows a wishbone harness. The wishbone harness has two running light wires, one for each side of the trailer. Diagram 2 is the preferred method and it is more common...

    • How to Wire Optronics Right-Hand Trailer Stop, Turn and Tail Light, Part # ST8RB
    • The Optronics Right-Hand Trailer Stop, Turn and Tail Light, Part # ST8RB, connects with two wires. On the rear of the housing are holes to accept bare wire and underneath each one is a smaller hole that serves as a wire release; just insert a small pin (or something like a paper clip) to release the wires. The left-hand matching light is part # ST9RB. If you refer to the included photo illustrating a trailer-side 7-way connector you will be able to see which two wires from the connector...

    • Testing Trailer Wiring for Function to Troubleshoot Both Blinkers Turning on at the Same Time
    • On the Trailer Stop, Turn and Tail Light, 6-Function, Right Hand, # ST8RB, the back is labled, the brake light and turn signal wire (usually green) goes in the left connectors. The taillight wire (usually brown) goes in the right connectors. It sounds like the right turn signal wire is somehow connected to both turn signals. If your trailer wires have different colors, or the colors do not match the functions described above, you will need to use a circuit tester, like the Quickee #...

    • How To Connect Optronics Trailer Lights # ST8RB and # ST9RB To a Trailer
    • The quick connect feature on the Optronics Light, part # ST8RB, and part # ST9RB, means that you can connect the wires by inserting them into the four holes on the back of the light. It is not referring to a separate part. The wires would be stripped about 1/4 inch and pushed into the correct hole on the back of the trailer light. The holes are marked with the tail light function that the hole provides. The wire when pushed in the hole will automatically lock in place and give you a...

    • Can the Optronics Tail Light # ST8RB Be Used on the Left and Right Side of a Trailer
    • You should not have a problem using the Trailer Stop, Turn and Tail Light, 6-Function, Right Hand # ST8RB on the left and right hand sides of your trailer. It would be just a matter of wiring up the lights accordingly. On the # ST8RB there is an arrow that points to a wiring hole with the word Green. On the right side of your trailer this will be correct, but on the left side of the trailer you would need to install the yellow wire there.

    • Can Redline Light Guard be Used with Optronics ST8RB and ST9RB Tail Light Assemblies
    • The Redline Light Guard # LG440NP referenced in your question is designed to fit the Peterson Square Trailer Tail Light # 432400 and # 432200, however it can also fit other tail light assemblies. The Optronics Tail Lights # ST8RB and # ST9RB that you also mentioned feature very similar dimensions to the above Peterson assemblies and will absolutely work with the Redline Light Guard. The guard itself has an inside dimension of 5-1/2 inches wide, 5 inches high and 3 inches deep. This will...

    • Recommended Replacement Trailer Lights With Side Lights For Small Utility Trailer
    • We have just what you are looking for. I recommend the LED Submersible Trailer Stop, Turn and Tail Light, part # STL8RB. This is for the right side of the trailer and is a stud mounted LED light. It has the side marker light that illuminates when the running lights are powered. For the left side of the trailer you will want part # STL9RB. I have attached a product review video and have also attached a drawing that shows the dimension for these lights you can take a look at.

    • Troubleshooting Trailer Running Lamp Circuit on 2005 Ford F Series
    • I am assuming you are speaking of the 7-way trailer connector. Use a circuit tester like part # 40376 on the pin in the 11:00 position on the trailer connector. If you do not have voltage on that pin while the headlights or running lights are on, you most likely have a blown fuse. The lid of your fuse box should have a legend showing which fuses protect which circuit. This information should also be provided in your owners manual. The fuses might not necessarily be located in the...

    • Can the Bulb in Trailer Stop, Turn and Tail Light ST8RB Be Easily Replaced
    • The bulb # ST8RB trailer tail light can definitely be replaced, and to do so is not difficult. The face of the light taken off by removing four small screws, and once this is done you have access to the bulb socket and can proceed with changing the bulb. The replacement bulb for this light would be part # A1157B.

    • Availability of Replacement Lens for Do-Ray 169
    • I was not able to find any specifics about lighting products from Do-Ray, nor one for a lens with the reference number 169. If you can submit a photo of the part you need along with measurements I'll be glad to check for a replacement. If you prefer you can choose a new light fixture using the link provided.

    • Using a Circuit Tester to Find Taillight Functions on a 1985 Ford F-250
    • I actually do have a diagram that you can look over to help with wiring trailer lights and the 4-Way wiring harness. I have included a link to the page below. The best way to find the functions of the wires on the 1985 Ford F-250 is to use a circuit tester like the Quickee # 3808. You will need to test the wires behind each taillight for function. Behind the left taillight, the wire that carries a signal in unison with the blinker connects to the yellow wire on a 4-Way harness. This...

    • Preferred Method of Grounding Trailer Lighting Circuits
    • Running a direct ground up to the trailer tongue or junction box would certainly work, but the only time I'd see that as being necessary is if the lamps were connected to a non metallic structure or a metallic structure that wasn't directly connected to the trailer frame. If the lamps aren't connected to a metal structure in direct contact with the trailer frame, you can use a short length of # DW02359-1 wire with a # DW05702-1 ring terminal on each end to serve as a jumper wire that joins...

    • How to Connect Trailer Wiring to Optronics # ST8RB and # ST9RB Trailer Tailllights
    • If you have the Optronics # ST8RB and # ST9RB, no connector is needed. On the back of the taillight, there is a hole for the stop/turn and a hole for the running light wire. Each of these holes will have a smaller hole directly below it. Strip back the insulation on the wire by about a 1/4 inch, twist the copper strands of each wire tightly and push it into the hole in the back of the lamp as you're pushing a small screwdriver into the smaller hole. Once the wire is fully inserted, remove...

    • Installation Method for Optronics 6-Function Trailer Stop, Turn and Tail Light # ST8RB
    • The Optronics 6-Function Trailer Stop, Turn and Tail Light # ST8RB that you referenced does not require a bracket for installation. This light is of the type that uses the two threaded mounting studs, spaced 2-inches apart, to attach to your trailer. These mounting studs also serve a second purpose; they provide the ground connection to complete the electrical circuit. Please refer to the linked video. Certainly if you wanted to mount these with a bracket you could use a simple L-bracket...

    • Comparing the Power Draw of LED Trailer Tail Light STL8RB and Incandescent Version ST8RB
    • LED lights draw considerably less amperage than incandescent lights. They also run much cooler. These 2 features are why LED lights last so long. The incandescent version of # STL8RB is # ST8RB and it draws 2.5 amps for the stop/turn signal functions and 1 amp for the running light functions. And the LED version draws 0.259 amps for stop/turn functions and 0.062 amps for running light functions.

    • Running Lights Function but Brake and Turn Do Not on a 2006 Carlson Utility Trailer
    • It could definitely be a ground issue. Since you were able to duplicate the same result with the same trailer on two different vehicles, than it is pretty safe to say the problem is somewhere on the trailer. I would start with the trailer connector and work back. Trace the ground wire, usually white, back from the connector. Make sure it has a good clean connection to the metal of the trailer frame. Paint, rust and corrosion can insulate connections so make sure it is good metal to metal...

    • When Should My Trailer Lights Be Working
    • When the vehicle is not running and the key is in the off position, the only functions that should be working on your vehicle and trailer will be the headlights and tail lights as they are not tied into the vehicle's ignition system. If you vehicle's brake lights come on when the brake is applied, then your trailer brake lights should come on as well. It is likely the turn signals will not function while the vehicle is not running and the key is in the off position. When the vehicle is...

    • Is There More than One Bulb in Optronics ST8RB and ST9RB Trailer Lights
    • For the trailer lights # ST8RB and # ST9RB there is only one bulb inside the housing and it is a 1157 like you mentioned. For a replacement you would want the part # A1157B. The light from the one bulb lights up the side and the front of the assembly.
