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.

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

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

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

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 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. I agree with others to silicon the area after installation to prevent water intrusion. Great service! Highly recommend etrailer!33542

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

  • 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 # 3808, to

  • 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 cont

  • 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 also carr

  • 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 main fus

  • 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 provi

  • 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.
