Today on our enclosed trailer, we're going to be installing the Optronics Ear Mount Trailer License Plate Light with the plastic housing and gray in color, Part Number LP51CB. Depending on your trailer will depend on how much of the interior you may need to take apart to gain access to the wiring to install the new trailer license plate light. We've also gone ahead and removed any of the old license plate light that was still on the trailer. Now that we have our surface ready to install our new license plate light, we'll go ahead and feed the wire through the hole so that the wire goes into the trailer itself. We'll go ahead and hold our light up into place and then mark the two holes. We'll then set the light aside for now. Next we're going to take two self tapping screws and pre-drill the holes into the trailer.
We'll then back each of the screws out and then put the light up into place, feeding the wire through a center hole allowing it to go into the internal part of the trailer. Then we'll go ahead and take our ratchet and put our screws back in, holding the light in place. Now in our case we needed to remove a couple pieces of internal trim to gain access to the wiring to install the new light. Now that the trim is out of the way, you could see here that we have our wire hanging down. It's part of the running light circuit. Now that that's done, we can go ahead and connect our wiring.
We use a simple butt connector here to connect our running light wire in with the wire coming out of the back of the license plate light. The butt connector that we'll be using today is Part Number DW05714. Once our connection's made, we'll go ahead and wrap it with some electrical tape to give it a little more protection. Now we'll go ahead and test the light before we put our interior back together. As you can see here, with our running light circuit on on the trailer, our license plate light comes on. Now that we've tested it, you can go ahead and put your interior back together.
Again depending on your exact model of trailer will determine what you have to reinstall. In our case, it's a couple pieces of trim. Once our trim is back in place, we can go ahead and close the door up and that'll complete the installation of the Optronics Ear Mount Trailer License Plate Light, Part Number LP51CB. .

So far so good. Thanks for the follow up.
works great
Worked ok. It's not an exact fit like the other lights I bought from etrailer. My old light fixture had a metal frame that went around the whole license plate area; this one didn't fit exactly. Nothing wrong with this light, just a slightly different design. I made it work rather than returning it.
I'm in the process of bringing my '84 tilt bed trailer back to decent condition and needed lights, etc. I went to the website and was able to find everything I was looking for. Ordering was easy and shipping was scheduled to arrive on July 6th. To my surprise, it showed up on the 2nd, in good condition and was exactly what I was looking for. Thank you for the excellent service.
I have a 2010 mission trailer for my snowmobile and noticed recently my marker plate light was out,the unit needed to be replaced,ended up findind an exact match here on ETRAILER.COM Thanks.. you guys never disappoint
I just bought a 2006 goose neck trailer that needed some minor repair. Wanted to match existing good parts. This was an exact replacement on this old LONGHORN trailer.

Got the parts I ordered in Excellent condition. Installed the Roof Vent with ease. I did have one little challenge. I disposed of the box the Roof Vent came in. It is now time to mount the license plate light. I could not find find the light anywhere. Well, I was getting ready to call E-trailers about the missing light, when I decided to get the box out of the trash. Well, it was wrapped up in the paper. Next time I will look a little closer.
Very pleased with with the products from E-trailer. They got my business and will tell my friends about E-trailer.
