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

Optronics Dome 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 (SMT). 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.

Recessed, Bolt-On Installation is Easy

Optronics Dome Light Installed

This dome light is incredibly easy to install as an upgrade or direct replacement of your existing light. Because it has a low-profile, recessed design, you will need to cut out a 4-1/2" diameter hole if you're not directly replacing a light. Then using the built-in flange and hardware (not included), bolt the housing into 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).

i order on the 21st you said in stock ready to ship. then i get more messages saying will ship on 7-1. so it took you 10 days to figure out how to ship it?


They were a prefect match to the ones i replaced


These lights are bright and well made. Easy to install.

I’m buying 1 more to put in the ceiling above the shelves in the V Nose.


Lights were easy to install and are very bright. I install 4 inside my 36 ft. horse trailer and I can load and unload horses well illuminated. I replace my old bulb lights with the LED's and couldn't be happier. I would recommend to anyone that needs a light of this design.


Great product, simple replacement, nice bright white light, instead of dim faded light





GREAT! No problems.


Looks great and is exactly what I needed









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.

  • Can Opti-Brite LED RV Dome Light # ILL29CFB be Used with Dimmer Switch
    If your RV had an LED compatible dimmer switch you could dim the Opti-Brite LED RV Dome Light # ILL29CFB but a standard dimmer switch would not work with it.

  • 6,000K Color Temperature Light Recommendation
    For a 6,000K light, I recommend the Opti-Brite LED RV Dome Light - 500 Lumens - Flange Mount # ILL29CFB. This light is 5-1/2" tall, 5-1/2" wide, and 7/8" deep with a a lens diameter of 4".

  • Can Diodes of LED Puck Light be Replaced
    If the LED diodes are going out on a puck light like the Opti-Brite LED RV Dome Light # ILL29CFB or Glantastic Dome Light # 328-K-58L349 then you'll unfortunately have to replace the entire puck light itself. Lights that use LED diodes are meant to survive a really long time so the bulbs, or diodes in this case, aren't designed to be replaced like what we see with traditional incandescent bulbs. If you can give me the specs of your current puck lights I can see if we have something that...

  • Does Glantastic Make An LED Dome Light With A Bright White Color Option?
    Unfortunately, Glantastic does not have a bright white version of that LED Dome Light # 328-K-58L349 but I do have the closest light we do carry. It will not match your Glantastic LED RV, but it is as close as I can find. The Opti-Brite LED RV Dome Light # ILL29CFB is a recessed mount with a bit bigger diameter tan your lights but not by much. only about an inch or so. This light will give you 500 lumens which is quite a lot compared to the 197 lumens on the Glantastic. This is the closest...

  • Recommended Replacement LED Puck Lights For A 2018 Tiffin Allegro Motorhome
    Based on the pictures you provided it looks like you have a 4-1/4" surface mounted puck light. We don't have replacement PCB LED boards I do still have two replacement options for you: Option 1: Glantastic 12V RV LED Puck Light # 328-K-58L34P9. This light has is 4-1/4" in diameter but requires a cutout hole approximately 3-1/4" in diameter. You could trim the current hole a bit more to make this fit. Option 2: Gustafson 12V RV LED Puck Light # 277-000341. This light is 5" in diameter...
