Features to know about

Simple Light for Plate Visibility: Compact Incandescent Design

Keeping your plate visible is easy with this compact 2-5/8" long by 1-5/8" wide light. It’s built with a clear lens and incandescent bulb that give off clean, even light for plate illumination. The gray-coated housing looks neat and low-profile once mounted, making it a simple way to stay compliant and visible at night.

Optronics LP56CB adhesive-mount license plate light with gray-coated rectangular housing and clear lens, shown for trailer or vehicle installation.

Quick Mounting Where You Need It: Adhesive Surface Setup

Perfect for tight or tricky spots, this light mounts using an adhesive base—no need for drilling or brackets. It sticks securely to the surface and stays put, keeping the install smooth and straightforward. It’s a good option when you want a clean look without extra hardware showing.

Easy Maintenance: Replaceable #168 Bulb

When it’s time for a new bulb, you won’t have to replace the whole light. It uses a common #168 replaceable bulb, so upkeep is quick and inexpensive. Just swap the bulb and you’re good to go again, no complicated wiring changes needed.

Reliable Basics: DOT Approved and Backed Warranty

You can count on this light to meet visibility standards—it’s fully DOT approved. The single-wire design keeps wiring simple (power only; grounds through the mount), and the housing carries a limited 3-year warranty that excludes bulbs. Straightforward, durable, and ready for the job.

Video Transcript for Review of the License Plate Trailer Light

Ellen: Hey, everyone. I'm Ellen here at etrailer.com, and today we're taking a look at the License-Plate Light with Gray Housing.Now this is going to help you to illuminate your license plate on your trailer so that you can stay compliant with any local and state laws, so it is DOT-approved. And it's just going to have a little incandescent bulb inside there to illuminate that license plate for you, so I'm going to undo the wire here and we'll take a look at what that looks like whenever you have it installed.It does have a little grommet here to provide a little cushion for your light against your trailer, but our power connection will be made with this black wire, and then our ground is actually going to be made through the hardware. So, whenever you put your hardware through, it makes contact with the ground tab on the inside there. I'm just going to put my little alligator clamp through, try to grab on so we can get that connection made, and turn it on there. You can see our light comes on.

Not super bright but enough to give us some light to illuminate that plate.I'm going to get this situated and then I'll shut off the lights in the studio so you can get a better idea of what that's going to look like. Whenever you go to mount this up, you will need to remove the housing so that you can get your hardware in place. I'll show you that in a minute, but just wanted to give you an idea of how bright that is. Yep. My connection going there.

So it gives us enough light to get us moving.I'll turn the lights back on and I'll show you how to take that cover off. The easiest way to do it is really just to grab a flat blade screwdriver, sort of pry out along the edge. You just want to be careful that you don't mar it up too much, so it's something that's got a fairly flat or thinner edge so you can get some good leverage against that edge. You might have to start on one side and then move to another until you get it pried up.The bulb inside here is a 168 or 168 wedge-style bulb, so pretty easy to find a replacement for that if you ever need to change it out. Once you have that cover off, now you can mount this in place.

You will need to provide your own hardware. It does not come with anything, any hardware to get this attached. And as you can see there's that our ground connection there. So once that screw goes through, it'll create our ground. Once it's mounted, put the cover back over, pop that into place.

I don't think it matters which way you put it as far as the housing goes. There we go.So let's go over some measurements. As far as the outside width side to side, it's about 2-1/2" at the front end. If we go over here, it's about 2-3/4" or 2-5/8. The total height is about 1-3/4, and the length is about 2". The distance between our mounting holes, center to center, it's about 1-3/4", and the diameter on those holes is about 3/16. The lead coming off for our power wire, you get about 5-1/2" of wire to work with there, so this will get you on the road with your license plate lit up. It is, again, DOT-approved and it does come with a limited three-year warranty on the housing, but not on the bulb.But that's going to do it for our look at the License-Plate Light with Gray Housing.

Broken trailer license light. New one from etrailer was inexpensive , easy to install and works great.
Can't ask for more



by:

I received the package on the exact day that you said it would arrive. However, I have not gotten the items installed yet due to other projects under construction. The items purchased look exZActly like the old items, so if they all work, it will be great. They were ordered to replace items not working on an older Karavan snowmobile trailer, so as I said as long as the function, everything should be great. This goes for all of the lighjts ordered at this time.



by:

These lights are a good replacements for trailers.I also use them on military CUCVs that I restore.Military trucks never had license plates.
Easy to install and comes with bulb too.



by:
