Optronics ILL46 LED Opti Brite RV Dome Light - Submersible - 9 Diode - Rectangle - Clear Lens - Diagram

Need extra light over your RV kitchen sink for when you do the dishes? Or perhaps you need to upgrade the dim, old lights in your travel trailer? This dome light has cool white LEDs that give you brighter light underneath a kitchen cabinet, in a walkway, in a closet, or inside your enclosed trailer. And the sonically sealed housing is waterproof so water won't leak in and damage the LEDs.

Optronics Dome Light LEDs

LEDs are more energy efficient, last longer, and burn brighter than lights with incandescent bulbs. You won't have to worry about replacing bulbs that have brittle filaments. And because LEDs draw minimal power, the light won't drain your battery, overload your circuits, or produce too much heat.

LED Circuit Board Has Surface-Mount Technology

Unlike other LED lights, this dome light has an LED circuit board with durable, surface-mount technology. This technology will better resist the shock and vibration that happens when you drive over rough roads. And it improves heat distribution, which means that you won't burn your fingers when you need to do maintenance.

Raw Lumens vs. Effective Lumens

Lumens are utilized to measure the actual amount of light that you can see and use from a light source. If you need a super bright light for a workspace, you will want to go with a light that has a higher lumen count. If you want a softer glow in an RV living space, you should go with a light that has a lower lumen count.

Light sources typically have 2 different kinds of lumens: raw and effective. Raw lumens represent the natural amount of light that a manufacturer says their light fixtures can produce. Effective lumens, on the other hand, represent the usable brightness of the entire light assembly, including the drive method or any lenses or reflectors.

Surface-Mount, Bolt-On Installation is Easy

Optronics Dome Light Installed

This surface-mount dome light is incredibly easy to install as an upgrade or direct replacement of your existing light. Using hardware (not included), bolt the housing onto the ceiling, wall, or cabinet. The light wires to a switch inside your RV and hooks up to ground (white wire) and power (black wire).

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..

Exactly what I was looking for and needed.Replaced a dim incandescent light with an LED.



Still working and just as bright as the day I installed it.


Added 4 of these during a rustic hunting cabin lighting project. These are for the shed and provide awesome lighting. I didn't realize the back side of the shed door was cream colored because we never closed the door before due to needing all the light we could get. Because it is a shed and we run these off of batteries I used a standard bathroom fan timer switch to make sure the lights don't get left on forever.


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.



The lights are great. I’ve had absolutely zero issues with them. So much brighter than the ones they replaced and easy to install.


Bright easy to install and very good pr ice


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!


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.



The light still works like the day I installed it so would say it is a dependable light. It produces quite a bit of light and really helps when rooting through gear at night. This was a very good purchase.


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

Thanks in advance

Love it super bright, installed as kitchen exhaust vent light now I can see what Im cooking, will send picture later, trailer is in storage


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


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!!




they were ok, a couple have tapped out since I installed them but they were very affordable and bright enough

Excellent LED light. No complaints, easy to install and run off of battery.


Great item. Used it for cab light for my side by side. It is super bright and works very well.


These lights are the brightest for a small light. Works amazing.


Should work great on my 12V system in my off grid camp.


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


Just as I had hoped it would be. It makes good light and is simple and clean.
