Optronics Trailer Lights STL8RB Review

Video Transcript for Optronics Trailer Lights STL8RB Review

Today were going to review part number STL8RB. This is the Optronics LED submersible trailer stop and turn taillight. This is 6-function light. It has 11 LEDs and it is for the right-hand side of the trailer. This versatile light will serve 6 functions for trailers that are less than 80 inches wide. Functions will be stop, turn, tail, rear reflex, side marker and side reflex.

This is a submersible corrosion resistant light. The molded plastic housing and durable lens will provide all weather protection against corrosion. This light has 11 LEDs diodes which will draw .259 amps at 12.8 volts when the stop and turn lights are on and it will draw .062 amps at 12.8 volts when the taillight is on. This light also features a screw-down replaceable lens. It is a universal mount with 2 studs on the back.

The distance between the studs will be 2 inches and it does connect by a 3-wire design which will be the white wire for ground, the brown wire for taillights and the green for stop and turn. And a couple of quick dimensions for this light. The overall length from side to the side marker will be 5 3/16. The depth of the light will be 2 11/16. The size of the light itself will be 4 by 4 .

Now I want to give you an example of what the brightness of the light will be. I have a power supply here. Well hook the white to the ground and well hook the brown up to give you an idea. There is the taillight. And then well hook up the green wire for the stop and turn.

And now Ill turn off the overhead lights to give you an idea in the dark. This will be the taillight brightness and that would be the stop and turn. And that should do it for part number STL8RB.

Expert Answers about LED Submersible Trailer Stop, Turn and Tail Light, 6-Function, 11 Diode, Right Hand - STL8RB Do you have a question about this Trailer Lights?

How Do I Convert My Incandescent Trailer Lights to LED Lights
Yes, you just have to remove the old lights, match the wires and mount the new ones. Please note, that it is usually not a good idea to mix LEDs and incandescent lights, so if you have have side markers or other lights on the trailer, make sure you switch those to LEDs as well. Incandescent lights draw much more amperage than LEDs do, and if they pull that current through the LED fixtures, the LEDs will burn up. We have LED side markers and clearance lights like part # MCL36AB and part # MCL

Not Getting Turn Signal Function When Using LED Bulbs On A Trailer
LED bulbs have little resistance on their own, so when used with turn signals they can create a hyper flash situation, which is a fast flashing of the bulb. To determine if you will need a load-resistor kit like the Putco LED Light Bulb Load-Resistor Kit - Ceramic, # P230004C, you will install the bulbs and when the turn signals are activated, if the bulbs hyper flash you will need to install the load-resistor kit. This kit will prevent the turn signals from hyper flashing. You will need one kit

Troubleshooting 5th Wheel Trailer Clearance Lights Blinking with the Turn Signals
When using the brake and turn signal at the same time, you are drawing more power then just with running lights. Since some of the LEDs blink, they may inadvertently be attached to the turn signal wire on the trailer. Most trailers have one wire that carries both turn signal and brake light functions and one wire that carries running lights. I would check to make sure the correct wire is run to the new clearance lights. An LED clearance light like # MC65RB will have two terminals or wires. One f

Can Trailer Tail Lights be Grounded to the Towing Vehicle Instead of the Trailer Frame
When installing the LED Submersible Trailer Stop, Turn and Tail Light, # STL8RB, you will want to ground it to the trailer. Having a ground that is attached to the tow vehicle would be so long it could make the ground ineffective. Also, you would have to disconnect it every time you disconnected the trailer. The movement of the trailer could also pull the ground loose if it were attached to the tow vehicle. If corrosion is a problem, you will need to find the best place you can near the mounting

These types of lights will also need to be attached to a clean and corrosion free metal surface. A bad or absent ground could be ca

Can a Passenger Side Tail Light Be Used on the Driver Side of a Trailer
Left side tail lights have a clear lens on the bottom to light up the license plate. Right hand side tail lights do not. If you were to use the right hand side light, # STL8RB, you would need a separate light to illuminate the license plate. The left hand side light that matches is # STL9RB.

LED Marker Lights on Trailer Stopped Working After 5 Years
Since you have checked the ground connection and tried a different grounding point. I would check to make sure the lights are getting power by using a circuit tester like part # 3808. You will want to inspect the power wires going to the the lights to make sure there is not any frayed or shorted wiring in the system. Then, I would inspect the vehicle and trailer side connector for corrosion. Corrosion in the connector could be causing a bad connection and preventing the lights from getting po

Difficulty Replacing Lens on Optronics LED Tail Lights
I contacted our representative at Optronics about replacing the tail light lens on your Optronics LED tail light lens. Optronics has made a change in the way the # STL8RB and # STL9RB LED Lights are made, now the lens and the LED diodes are all one piece. You would need to replace the entire light assembly as you can no longer replace the lens. The smaller sidemarker lens on the tail light assembly is replaceable, but the main tail light lens is not.

Troubleshooting Left Blinker Not Working on a Trailer
It really sounds like the ground is not making good enough contact on the left turn signal/tail light and because of that it is able to draw enough amperage to illuminate the blinker function of your bulb. There is a chance the converter box of your setup could be wrong, in order to test that you will need to test for voltage coming into the box and then for voltage coming out of the box with circuit tester like part # 3808. If you find that there is voltage going into the box on the left tur

Troubleshooting Right Turn and Running Lights on Trailer Towed by 2007 Ford F150
I would recommend starting at the 7-way connector at the rear bumper of your truck. Use a circuit tester like part # 40376, and activate the right turn signal. Test the pin in the 3:00 position. The tester should flash with the turn signals. When the brake pedal is pressed, this pin should light up the tester as well. Repeat the test on the pin in the 9:00 position which is the left turn/brake and the pin in the 11:00 position, which is the running/ marker lights. Check the pins for excessive

Trailer Lights Malfunction on 2007 Ford F-150 Towing a S and H Horse Trailer
The first part of the problem sounds like a bad ground. A bad ground usually shows up when the system is under load. Start by checking the trailer and vehicle side connectors. Clean out any dirt or corrosion built up inside and in the backs of the connectors. Next check the ground on the vehicle side connector. It should be attached to a clean, bare metal surface on the vehicle frame. Also check the trailer side main ground. It should be attached to a clean, bare metal surface on the trailer

Troubleshooting why an S and H Trailers Brakes Will Not Disengage
It sounds like the issue is somewhere in the wiring of the connector that was lost and had to be replaced. It sounds like you may have the 12-volt power source swapped with the brake output circuit on the trailer connector. That would explain why your brakes are on all the time. The first thing I would check would be the brake output circuit on the trailer side of the connection. I would check for voltage on the brake output circuit on the truck side of the connector first to see if the volta

Right Side Trailer Brake and Turn Signal are Not Working but All Other Lights Work
This is a classic ground problem, especially since everything else is working. It could be at the trailer connector, vehicle or trailer side, or at the light itself. Start with the vehicle side connector and make sure it is properly grounded and that any corrosion or dirt is cleaned out of the connector. Then do the same with the trailer side connector and the main ground for the trailer. Some lights ground through a wire and others ground through the mounting studs. In both cases the grounds

Trailer Wiring Harness and Installation for a 2006 Ford Mustang GT
If you are trying to install lights like # STL8RB to your 2006 Ford Mustang the problem could be that the car has separate turn signal and brake lights while trailer lights have a combined turn signal and brake light circuit. On light # STL8RB, the white wire is ground, the green wire is stop and turn lights, and the brown wire is running lights. If you need to add trailer wiring to the car so that it can tow a trailer, you will need to use # 119176KIT. I have included a link to the inst

Wiring Replacement Taillight on 2006 Crossroad 5th Wheel Trailer
Typically, the black wire on the 5th wheel would carry the running light circuit, the white wire would be ground and the red wire would be for the turn signal/brake lamp. The best practice would be to confirm this by using a circuit tester like part # 40376. You can test the wires exiting the 5th wheel as each taillight function is activated in order to confirm which color wire serves which function. The brown or black wire on the # STL8RB carries the running lights, the white wire is the gro

Turn Signals and Tail Lights Blink on Trailer After Installing LED Bulbs
It sounds to me that when you activate the left turn signal, the tail light signal (lower intensity signal) on the right tail light blinks. My first thought is there is a wiring or ground issue somewhere on the trailer. It may have not been immediately evident with the incandescent bulbs because they require more power to function than LED bulbs. LED bulbs require only a fraction of power to function and any type of power issue could trigger other lights to function. To troubleshoot this iss

Will the LED Submersible Trailer Stop, Turn and Tail Light # STL8RB work on a EZ Load Boat Trailer
It sounds like the two wires on your trailer wiring are for the stop/turn and tail light functions and the ground is through the mounting hardware of the light assemblies. The # STL9RB and the # STL8RB should still work well for you. You will just need to ground the white wire so that everything will function.
