Video Transcript for Optronics Trailer Lights - Tail Lights - ST20RS Review

Today we'll be reviewing part number ST20RS. This is the Optronics Trailer Light for the passenger side. The round trailer light is going to serve as your brake light, turn signal, and tail light. It's got the red acrylic lens that's simple to replace. It's going to attach with the two included screws. Very easy to change incandescent bulb that's going to offer a bright light.

It's going to sit in a shock-proof socket for a long bulb life. It's also going to feature the black enamel-coated steel housing that's very durable and strong, as well as corrosion resistant. Here on the rear, it's going to have the two lead wires exposed. These are the wires needed to connect your light, and then the unit's going to ground through the mounting hardware. This is a surface mount design so it's going to mount using the two studs on the back of a housing. Those are included.

They simply just slide into the channels and then you can adjust them as needed to best suit your towing application. It is Department of Transportation compliant so it meets FMVSS108 and CMVSS requirements for automotive lighting. Again, this is for the passenger side. If you need one for the driver's side, you can find that here at etrailer.com using part number ST21RS. This 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. It's a double filament. Power draw is at 12.8 volts so when using the brake light that's going to be 2.3 amps, turn signal is 2.3 amps, and the tail light is 0.9 amps. Again, the installation is going to use those two studs that are included, and once those are installed they're going to measure 2" center on center apart from one another. We're going to go and connect this to our external power source so that we can see what the light looks like with power running to it and with our overhead lights turned off. So go ahead and make all of our connections.

The red wire's going to be for the tail light function, so we'll get that connected. Then the black wire on the back of the housing is going to be for our stopper 00:01:59 and turn signal. You can see here it sends out a nice, consistent signal. This is going to be the tail light function. It's going to brighten up when we apply the brakes, and it's going to do that same thing when we apply our turn signal. That's going to do it for today's review of part number ST20RS. This is the Optronics Trailer Light for the passenger side of your trailer. .

Not the first time I have ordered from etrailer. Good products, good prices and always shipped quick 656862

Well, the UPS man was NOT happy. He chewed on me for not having my name on the package. I reminded him that I didn't send the package. The address, minus the name, would have gotten to me with no fuss; by USPS. Not so with UPS. They need a physical address, not a post office box number. I happen to winter in a mobile home park which has private streets not recognized by USPS. Hence his problem. He had no name to look up and only a PO box #. However, the tail lamps were just what I wanted and they arrived in good shape. 611232

Product Review:I had these type lights on an old Toyota rust-bucket with a wooden bed which still is my most loveable vehicle; can't find these lights locally (N/W NC mountains); found your ad online and hoped these would match those already on the Toy and replace some damaged and rusty; couldn't believe I could get exact replacements, but I sure did; order date March 29 early AM, mailman handed them to me April 31 at 1 PM at my house "in the same year!" They had traveled, according to map, across from the edge of Missouri through the southern edge of Indiana, across the length E-W of Kentucky, SW Virginia to Greensboro, NC, then backtracked on land back to my home via USPS to me. Put them to your ear and you could still hear the Mississippi!! Give it a big 5 stars! 362155
