Video Transcript for Ultimate Overview of the Optronics Trailer Tail Light

Today, we're going to be reviewing Part Number ST21RS. This is the Optronics Trailer Light for the driver side. The round trailer light is going to serve as your brake light, turn signal, and tail light. It's got the built-in license plate light as well. It's got the red, acrylic lens. It's very simple to replace.

It attaches with the two included screws. It's going to feature the easy-to-change incandescent bulb that's going to sit in a shockproof socket for a long bulb life. It's got the black, enamel-coated steel housing. It's very durable and strong, as well as corrosion resistant. Here on the back, it's going to expose the two lead wires to connect your light, and it's going to ground through the mounting hardware. The mounting hardware is included.

It's going to surface mount using those two studs on the back of the housing. They just slide into the channels here, and then you can adjust them as needed to fit your application. This light is designed to extend out from the trailer. It is Department of Transportation compliant. Again, it's for the driver side. If you need a light for the passenger side, you can use Part Number ST20RS, and you can find that right here at etrailer.com.

This light is going to give us an overall diameter of 3-7/8", with an overall depth of 3-1/16". The bulb type is 1157 double filament. The power draw is at 12.8 volts, so for the brake light, it's going to use 2.3 amps, for the turn signal, it's going to use 2.3 amps, and for the tail light function, it's going to use 0.9 amps. When installed, those two studs here on the back are going to give us a measurement, center on center, 2" apart from one another. We're going to go and hook this up to our external power source, that way, you can see what it looks like with power running to it, and with our overhead lights turned off. The red wire is going to be for the tail function, so we'll go ahead and connect that.

Then the black wire is going to be for our stop and turn signal. You can see here that it's going to send out a nice, consistent signal. You got the license plate illuminator here at the base, and then when we apply there brakes, it's going to illuminate for a more consistent, even brighter signal. It's going to have that same function for the turn signal as well. That's going to do it for our review of Part Number ST21RS. This is the Optronics Trailer Light for the driver side. .
