Optronics Dome Light Dimensional 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.

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

Optronics Dome Light Dimensional Diagram

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

Using hardware (not included), bolt the housing onto the ceiling, wall, or cabinet. The included trim flange covers the bolt holes to provide a clean, finished look.

Video Transcript for Opti-Brite LED Dome Light Review and Installation - Enclosed Trailer

Hey guys, Kevin here at etrailer, and today we'll be showing you how to install the Optronics Opti-Brite LED Dome Light. So our neighbor has to pull his race car in to his trailer every now and then. Depending on the race track that he's on because he doesn't always had the space. Pulling into this trailer before we put our lights in, it was very dim, he couldn't really see anything. So working on his car was gonna be really hard to do. So, instead we installed these LED dome lights that are gonna give him a much brighter visibility than any incandescent bulb and it's gonna last a whole lot longer.

They're very low profile dome lights. So these really only losing about 1/4-inch of space from the ceiling. So he doesn't have to worry about knocking into it. It's not like those bigger bulky ones that you'd see inside of a camper. These LED dome lights are actually compatible with both 12V and 24V systems as well.

So this installation is fairly simple. Your LED dome light is only gonna have two wires, your positive and your neutral. So, hooking that up to your wires is gonna be super simple. If you're just replacing in an existing light, it's gonna be straightforward. All you're gonna do is just remove your old light, hook this up to the wires that you already had ran.

If it's like our case, where I had to run separate lights all the, or wiring all the way through our trailer up to get to our switch, it's gonna take a little bit more time and be a little bit more invasive. But all in all, still a fairly simple installation. So what we're gonna do is we're going to mount our light up in the ceiling, closer to the edge. So I already got directions that he wanted it to be 6 inches from the wall cause' we actually have a little metal panel that sits right here. And then also, I kind of wanted to center it because we're gonna be running eight lights throughout our trailer here.

So I got this in the center of this patch because it's gonna be more appealing to the eye, and then 6 inches out. What I did so that I wouldn't mark up our ceiling here was just use some tape. Made my measurements exactly where I wanted it and drew the lines. So now we're gonna go ahead and we're gonna drill this out. You gotta be very careful, especially on these enclosed trailers because the ceiling here is really only an inch or two from this ceiling to the actual metal roof. So I'm using a hole saw with the center bit that's barely past that. And we're just gonna kind of rock it back and forth, that way I can cut through this ceiling without actually puncturing up into our metal roof. Now with that lose, we can just break that off and we have our hole. From there, I'm gonna be running my wiring down to a different light, so that every light's gonna work of with the same switch. So I'm gonna drill another hole back here, that's gonna be hidden behind our metal flashing that we have, that way I can wire this up to each of the other lights. So with my light, I'm gonna strip back my casing. Do it a little bit further than normal. Just because I'm gonna fold this, wire gauge is so small, I'm gonna fold the end over just a bit and then twist it up, just so, I can stick in it up a bit before sticking it in the butt connector. Go ahead and do the same thing to our other wire. And we can put two butt connectors on and crimp 'em down. And then we can run some wiring from our hole that's gonna be running to our light over to that hidden hole. That way I can wire this into all the other lights. While we're down here, I'm gonna go ahead and crimp on our wiring that we're gonna run over to our power and use red for my positive and yellow for my neutral. And now we can go ahead and stick this up in our ceiling. So I'm gonna stick my two wires through and I'm gonna try and get 'em over to that other hole. With it being so close, I'm not gonna bother taping these up and trying to use a fishing rod or anything to pull it through. All right, now we got that we can pull our light up into our spot. Get it how we want it and then screw it in place. Once they have it evenly placed, I'm gonna put one screw in to start and then I'm gonna get down and just double check that I got both sides straight. I don't want it looking crooked later on. All right. And now we can snap on our cover and then we can run our power wire over into our next light. All right. So now that we have our other side done and all of our wiring tucked up I'm gonna put our cover back in place and then we can make our connections to our power wire. So because I'm only putting a lot of wires together, I'm gonna split up what's gonna be going in one end of the butt connector. I got one side of our lights that I'm gonna hook up with our power and our neutral wire and before you go ahead and do any of this make sure that you have your power off. I'm already gone ahead and tested with our multimeter making sure we're good to go but I'm gonna twist up my power, on my butt connector, crimp that on and now, for our other side of our lights, I'm gonna hook this into the light where there originally was mounted to our ceiling here and we're gonna hook that into our other side here. To do that, I can strip back my casing on my wire now. All right. So same thing, we're gonna hook up our powers and our neutral wires and then we're gonna run those into our butt connectors. We'll crimp 'em down and we can go ahead and shove all of our wiring back up in the ceiling. And as we're going, I'm gonna start screwing in my light panel here. So now we have all of our wiring in place. I closed the toy hauler door back up so we can get a good little view here of how the lights are now. As you can see, way brighter. And now our neighbor's gonna have way better visibility when he's trying to work on his race car in between laps. Well, I think that about does it here for our installation of the Optronics Opti-Brite LED Dome Light. My name's Kevin, thanks for watching..

Totally lights up every corner of my 6x6. Easy install, everything I need.


Worked great.



This light is great. Very bright, and easy to install. Huge upgrade over the dome light that Pace put in.


Thank you!


Very bright, easy to install, happy with the product.




No issues at all. Was a good up grade to my car hauler.







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


I will be using these to replace 4' fluorescent in a 28' enclosed trailer. I have not yet installed them, however I connected them to 12-volt power and they are very bright. The flush mount design will make it very easy to install without any retrofitting or needing to do cut outs.


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+.


this was a great product, and an easy swap out. We have had it nearly a year now with no problems.
Great service, quick response time, I will work with etrailers in the future!


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 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.


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.




Great light output. I used them in my enclosed racecar trailer - lots of light and very little battery draw.


I cant say enough good things about these excellent lighting fixtures! I have (2) of these fictures install in my 20' Box - they are low profile, sensor operated and absolutely make it a pleasure and also very safe to work in this space. Make the investment, you will not regret it! Also, the etrailer customer service is absolutely outstanding, with excellent communication and follow up!


Dimmable option is a great plus, have had no problems, will probably replace more fixtures in my trailer with these 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.


Simple to install. Very bright. Capacitive touch on/off works well.


very bright . happy with low profile


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.

  • Recommended Interior Lights For A 20' Enclosed Trailer
    For an enclosed trailer one of my favorite options is the Opti-Brite 12V/24V LED RV Dome Light # OPT98FR. These surface mount LED lights provide a bright white light to illuminate your trailer. They run on 12v DC power and only 0.74 amps for a more efficient light source compared to incandescent options. I've installed a ton of these in various enclosed trailers and it's a night and day difference once the installation is complete. We offer another version of these lights # OPT48FR that...

  • Recommended Interior Lights For An Enclosed Trailer Hauling Band Equipment
    Since the Peterson Great White LED Trailer Interior Cove Light # 359-1 only has a 300 lumen rating you would most likely need 24 or more to properly light up your 24' enclosed trailer. The mounting brackets on these lights would also require you to mount them in the corner where the walls meet the ceilings. Instead I recommend the Opti-Brite LED Dome Light # OPT98FR. These offer a 1,040 Lumen rating, which will provide a much brighter light for your trailer. They are a surface mount design...

  • Replacement Dome Light Recommendation for a Command Dome Light K-1030WSM2
    Thanks for reaching out! Your Command Dome Light K-1030WSM2 was discontinued back in 2020 and while we do have some replacement options for you, unfortunately none of them are going to be an exact replacement. The Command light you have measures 8-3/16" long x 4-7/8" wide x 3/4" deep overall and the closest options we have for that are the Opti-Brite # OPT98FR which measures 6-3/4" long x 3-15/16" wide x 3/8" deep overall, and the Opti-Brite # ILL06COB which measures 11" long x 4" wide...

  • Does The MaxxAir MaxxFan Deluxe Lid Allow Daylight Through
    Due to the design of the lid on the MaxxFan Deluxe Roof Vent w/ 12V Fan and Thermostat # MA00-05100K you really won't get much light passing through if any on your trailer. If you're looking for an option that comes with a light then we also have the MaxxFan Mini Plus Manual RV Roof Vent w/ 12V Fan # MA00-03801 (white) or # MA00-03851 (black), which comes with an LED light ring to help illuminate your trailer. It's not as powerful of a fan as the deluxe, but kills two birds with one stone....
