Video Transcript for Trailer Tail Light Spec Review

Today, we're going to be reviewing Part Number ST25RB. This is the 4-3/8" Round Trailer Tail and License Plate Light for the left hand side of your trailer. You can see down here, it's got a nice, clear part of the housing that's going to allow lights come through, so it's going to send some light down to the license plate area. The red, round trailer light is going to serve four functions. It's going to provide your stop and turn signals, your tail light signal, and your license plate illuminator. It's got a black, polymer housing that's made out of a durable plastic material. It's also going to feature replaceable lens and bulb that is an incandescent bulb.

Here on the rear of the housing, you can see that it has the stud mounts on it. It's also going to include the nuts that are on there, that way, you can get it fully installed. If we take a measurement to distance between those two studs, center on center, it's going to be right on 2". The wiring design is going to have the two lead wires for power, and then it's going to ground through the mounting hardware. If we take a look at the overall diameter, it's going to give us a diameter of 4-5/16", with a depth, just going to the back of the housing, of about 3-5/8". Now, we're going to go and connect this 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 brown wire is going to be for the tail light function, and then the red wire is going to be for our brakes and turn signal. You can see here, it's going to send out a nice, consistent signal. This is going to be the tail light function. You can see that that 00:01:54 allows the light to come through here at the bottom. That's going to be our license plate illuminator.

Then, when we apply our breaks, you can see how it brightens up, sends out a stronger signal. It's going to be the same thing when we activate our turn signals as well. That's going to do it for today's review of Part Number ST25RB. This is the Round Trailer Tail and License Plate Light for the left hand side of your trailer from Optronics. If you need one for the right hand side, you can find that right here at etrailer.com with Part Number ST24RB. .
