Optronics LPL58CB License Plate Light with Stud Mount Diagram

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

Surface-Mount Light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.

Video Transcript for Optronics LED License Plate Light Review and Installation

Randy: Hey guys, it's Randy here at We get inquiries from customers all the time about different lights and how to get their trailer set up. Today we're going to be taking a look at a license plate light. This is required in most areas to illuminate your license plate so it can be seen.The one we have here today is from Optronics. This is going to be an LED light, so it gives us cleaner and brighter light, and they tend to last a lot longer than your incandescent lights. You're going to see mainly in trailers nowadays when people go to rebuild them they start switching these lights out so they can get good, nice, clean, bright looking and fresh lights when comparing those to the incandescent type.This one in particular is going to be one of the better looking license plate lights that we have here on offer at etrailer.

You can see it has a really nice streamline look, but it also has that fully chromed face.Now this is going to be a polycarbonate case, so it's going to be pretty resilient, and it's sonically sealed, so we don't have to worry about any moisture getting in there. Without moisture getting in there our lens is going to stay nice and clear, and you see it gives us that nice, bright light that we're used to out of most LEDs.Also they use surface mount technology on this light. Essentially that's just a very rugged design. It helps us to insure that as we bounce down the road.. You know trailers bounce and move a lot, that we're not going to have any problems with the connections located inside.Now this is going to be available in two different mounting configurations.

You can see either the studded type here, where you'll pass that through your item and secure it on the back with nuts, or with a surface mount type like this. Now this is a very, very common one, but on a lot of utility trailers they'll often mount this to a flat piece of steel. Then you can simply pass that through and secure it on the back side.Now as far as dimensions go, the light is going to be about 4-1/8" wide. It's going to be about 2-3/4" long, about how far it sticks up off of the base that you mount it to. And it's going to be 1-7/8" thick.All in all, I really like light.

I like that it's got the polycarbonate lens that sealed up. I think it'll be a great addition. I think on just standard utility trailers you might go with something steel, because those tend to encounter a lot more stuff getting near them or wanting to bounce into them. But I think in a lot of situations where it's a camper, a nice enclosed trailer, car hauler, things like this, having this on there can really add a nice little touch.Now on the stud mount style you can see we're going to have about 1-3/4" from center to center on those mounts, so you'll just want to insure that that's the spacing you have and insure that that'll work on that plate.When we look at the bolt mount we're looking at 3-1/4" from center to center there. That's going to work out really well with kind of most of the older styles here.

We're going to pull this off and it should be a direct bolt on replacement for us. Ours happens to use a square bit, but sometimes these are 8-point. You just never really know. They might just be self-tapping screws, so use whatever bit you need to get that removed.Now we're going to trim our wire here. We're going to go around to the back side and gain access there so we can find our connection. Now in some cases if you have an enclosed trailer like this your hole may be large enough here where that'll pass in and out. If that's the case just pull it out. You can do it that way as well. Of course on the stud mount you're going to be going through a thinner piece of metal, so that shouldn't give you any issues at all at finding where that wire is.Now we found our wire on the back side that we're going to be tying into. I'm going to take our two wires here, we'll pass them through. Now we just need to line up our holes there and we'll get our original screws installed.Now as far as our inside connections go, start with our ground. Now if you have a ground wire you're going to connect it with a butt connector, just like what we will our next wire there. This one does not have a ground wire. It's a single line system, so we're just going to add a ring terminal on here. Get that nice and secure. We're going to use one of our self-tapping screws and we're just going to self-tap it right down there to the frame. That'll give us all the ground we need.Now for our power wire we're going to go to our running light signal here. It'll be the same one that yours was connected to. I just had to add extra wire in here. It's pretty rough looking, so we'll have some fresh wire to work with.I'm going to take these two and strip them back equally. I'm going to twist these together and we're going to use a butt connector to make our splice so we don't have to use any kind of quick connectors or wire nuts or anything like that. So they're both twisted together. They both go in one side of that butt connector and I'll crimp it down, make sure they're both in there really well, and that's just going to go to the other side.Now this is inside. I'm still going to use a heat shrink butt connector on it. It generally gives us our best bet about having a good corrosion-free connection. You can use a heat gun or a mini-torch to get this shrank down. Generally when I just do one I just use a lighter. The key is not to melt it. You just want to warm it up so it starts to shrink.Now at that point just want to test it out. As long as it comes on and works you're going to be ready to put this trailer back together.

LED License Plate Light - Submersible - 1 Diode - Chrome Housing - Clear Lens - LPL58CB

Average Customer Rating:  4.8 out of 5 stars   (5 Customer Reviews)

2-7/8" x 2-9/16" x 1-1/2". Waterproof trailer light illuminates your license plate. Clear lens under ploycarbonate housing. Stud mount to trailer. 2-Wire pigtail with power and ground.


First, a "kudos" to etrailer. Always good, always fast, always VERY informative. The LED license light solved a problem for me, and I'm sure others. There are several lights that one can obtain but this one has length to it. For me, this is the only one that would work on my tear drop trailer. The rear is round and my chrome license plate holder is a bit thick. Thus, the top and bottom of the plate holder are a bit out from the shell. This light will overcome that problem. Also, the quality of this light and it's chrome (plastic) plating is excellent. Just more good words about etrailer. You guys ROCK!


One year out, it still looks good and lights my plate.


Exactly what I was looking for, fast se rvice
