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.

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
