Optronics ILL46 LED Opti Brite RV Dome Light - Submersible - 9 Diode - Rectangle - Clear Lens - 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 internal components.

Raw Lumens vs. Effective Lumens

Lumens are used to measure the amount of usable light that is put out by a light source. Raw lumens represent the number of lumens that the manufacturer claims the LEDs are capable of producing. It does not include the light's drive method or the amount of light lost from the lens or reflector. Effective lumens take these factors into account and represent the number of lumens that are actually produced by the complete light assembly, not just the amount of light that the diodes are capable of producing. This light has a 540 raw lumen capacity and produces 380 effective lumens.

Video Transcript for Optronics Opti-Brite LED RV Dome Light Review and Installation

What's going on everybody Adam here with etrailer. Today, we're gonna be taking a look at the Opti-bright LED RV light. This LED light can be used in your RV, your camper, or your enclosed trailer like we have here. It doesn't have to be inside. It is a waterproof housing, so you can put it on the inside or on the outside, and you don't have to worry about the elements and getting to it. And it is gonna be for your 12 volt DC systems.

And it's gonna draw about 0.33 amps. This is gonna be a lot less drawl than some of the incandescent bulbs that we carry here. I always recommend going LED just because you can put two times as many LED lights up and draw the same amount as one incandescent bulb. And these are gonna last a lot longer than the standard incandescent bulbs. This light's extremely bright, and we have 1, 2, 3, 4, 5, 6, 7, 8, 9 diodes.

And it's kind of crazy that it doesn't have a whole lot of diodes, but it's really, really bright. It's about 380 lumens. The dimensions of the light are gonna be about 5 3/4" long by 2 3/4" tall. And it's only gonna sit out from the wall about 11/16 of an inch. The mounting holes are gonna be about 4 11/16" apart.

Now that we went over all the specs and stuff, the only thing that we haven't showed you is how to install it. So if you stick around, we're gonna show you. First things first, we want to figure out exactly where we want our light. I'm gonna replace the light that used to be here. If you have wires ran already, great.

We can skip that step. If not, we are gonna have to run a negative and a positive wire to where we're going. And it's always smart if there are wires already there, or when you're running them, make sure you figure out which one's gonna be positive and which ones are negative. So we connect them correctly. So what I like to do is just take the light, put that to the side for now, and I'm gonna be using heat shrink butt connectors. If you don't have any of these, definitely grab them. We do have them here at etrailer, and these are just gonna give us the best connection whenever connecting the wires. So strip them back, give them a twist and whatever direction you're twisting them kind of twist it as they go through there. So it's nice and secure. And then we can go ahead and clamp them down. We want to make sure they're nice and tight, especially if you are going to do what I'm doing and put the wires inside the wall. We really don't want these connections to be loose or come undone in the wall because we will lose the wires. And that's not fun. Give it a good tug, make sure it's nice and snug. And we'll do the same exact thing for other wire. Now we can grab our light, do the same thing. And of course, go to the ground side, and then to the positive side, squeeze them down and . we are pretty much ready to go. Before I heat these up and completely secure them. I'm gonna go ahead and kind of just let this light sit here, and I'm gonna flip the switch and hopefully we'll get some lights. And if it works, we can proceed. So, it works. So we will proceed. All you need is a little bit of heat to shrink these up. I'm using a heat gun, which is really fast, but if you don't have a heat gun, just use a hairdryer or something like that, and it will get the job done. It'll just take a little bit longer, but I really liked these connectors as they will feel it. So, if you're worried about moisture getting in there. Sometimes on trailers like this moisture gets in between the outside panels and our wood in here. And that's where these wires are gonna live. And it's nice to have a nice seal around the wires. So we don't have to worry about the moisture getting in there. And if we don't strip them down perfectly, this will help hold those wires in place so they won't come undone as easily. So that's always nice. We do have these at etrailer. So once that's done, cool down for a second or two, and then we can go ahead and start hiding our wires in the back where they belong. Where they're out of the way so it looks nice and clean, just like that. Then go ahead and position it to where we want. The hardware is not included, but you do want to use a Phillips head because we're not gonna be able to get a socket in this little hole. So, let's go ahead. And I'm gonna use a preexisting hole that we had before like that. And then we will, I'm gonna use a power tool. You pre drill the holes, you can probably get away with just using a Phillips screwdriver and do it by hand. But, I just had this thing laying here in the shop. So we're gonna use this. Just don't screw it down too tight because we don't want to crack the housing. All right, that's good. We want to make sure it's nice and level. Once that is good, we could do the second one, and we are done. And that'll do it for a look at the Opti-bright LED RV light..

Opti-Brite LED RV Dome Light - 380 Lumens - Surface Mount - Rectangle - Clear Lens - ILL46CB

Average Customer Rating:  4.8 out of 5 stars   (144 Customer Reviews)

5-3/4" x 2-3/4" x 11/16". Low-profile dome light illuminates an RV's interior with bright white light. Durable polycarbonate lens and housing. Surface mount with built-in flange - hardware not included. Accepts 2-Wire pigtail.


These lights are outstanding. They are slim design and bright. Easy to install. You do have to provide your own screws and wire connections, which does allow you the ability to choose what works best. Great product and highly recommended. The brightness is amazing for such a small thin light.


My led light arrived today, however not the screws for fixation, are they part of the lights? should have 2 per set. Thanks in advance

I have contacted the manufacturer and they the mounting holes measured at .16 inches.
-- Etrailer Expert Katrina B - 05/06/2022


I installed as a cargo light in the bed topper on my truck. It was wired into existing bed lights and comes on when they do. It has added a significant amount of additional light and is working great.


I've been looking for some time now for a dome light to put in my 1966 F100 Ford that was bright, looked good, easy to mount, and was affordable. This light met all. Thanks for a great product!


Prices were good, delivery was fast and customer service was great!


This light went into a small wet bath in an older RV. It was easy to install and provides an amazing amount of light. Great for shaving etc. but in the middle of the night when you are half asleep, it is almost too bright!!




Excellent light. Worked well for interior lighting of my cargo trailer.


Honestly it was a real simple install, the wires sealed nicely in the light assembly. After connecting it I turned it on for the first time and the light was perfect. It’s super bright and the leds aren’t blinding due to the opaque lens. Best cab light I’ve put in

The light is still working and still super bright! No problems so far

Review from a similar Opti-Brite Interior in RV Interior Lights

These are fantastic. Replaced two main lights, both controlled by a wall mounted switch, in our 21' travel trailer. The additional light from these is amazing. We can now see inside the cupboards and closets without needing a flashlight. Installation was easy and straightforward, just remember that LEDs are polarity specific. Also keep in mind that these do not have a switch in them, which is why I only replaced the two main lights. We like them so well we just ordered another to replace the bathroom light, also controlled by a wall switch. I would replace all the lights with these if they had internal switches.


Review from a similar Opti-Brite Interior in RV Interior Lights

I installed 4 of these lights low on the wall to assist in lighting the tie down anchors and straps in my car hauler trailer. They are very bright and easy to mount with 4 screws. These 4 lights and the 3 ceiling lights that I purchased from work great in making an enclosed trailer very bright inside. The surface mount makes these lights AAA+.


Review from a similar Opti-Brite Interior in RV Interior Lights

The lighting in my cargo trailer contained 4 incandescent fixtures that had burned out bulbs most of the time. They never were really bright even when all worked. I took this pair of photos at night so you can see the difference. The LED lights burn cooler, use less of my storage battery charge, and the bouncing of the highway won't harm them. Well worth the price and an easy installation.
