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 bright white LEDs that give you brighter light underneath a kitchen cabinet, in a walkway, by a workbench, or inside your enclosed trailer.

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 or overload your circuits.

Surface-Mount, Bolt-On Installation is Easy

Installing Gustafson Lighting RV Dome Light

This surface-mount dome light is incredibly easy to install either as an upgrade or a direct replacement of your existing light. To access the bolt holes, snap the lenses off the housing. Then, using hardware (not included), bolt the housing onto the ceiling, wall, or cabinet before snapping the lens back on. The light has a 2-wire design that hooks up to ground (white wire) and power (black wire). Once you're finished, you can then turn the light on and off using the integrated switch on the base.

Total fail on this order. Tire was back ordered. I decided to wait for it. The date code on the tire is 5/21, the new tire is 14 months old. The order was shipped in a box 2.5 times the size of the order. The halogen light I purchased was unprotected in the box with a tire rolling around on it from MO to VA. Sorry guys, big fail on this one.

I am so sorry that this happened to you! Was your light damaged in any way?

Light was scratched, and cover had rubber marks on it from the tire. I was replacing an identical light. My old cover was fine, so I used what I had. I made it work. Thanks

Super quality, excellent range of light. I went through 2 different lights before finding a good quality light that performs. Had my purchase one year now and extremely satisfied with this purchase.

Etrailer provides great quality products and stands behind what they sell. Product and customer service is excellent.


The replacement lights matched the existing lights nicely. Easy installation. All five were in place well under half an hour. I will order more of these as needed or even ahead of time

Still shining. My trailer lights were simple to install and are working great.

Great, super bright light that is compact and does the job. Wish it had switch to dim down a bit, but great value for the price.


The light output is great. t has an attractive streamline appearance. Although I should never have t, my only complaint is that once the cover is snapped into place, it is almost impossible to remove it without fear of breaking it.


Pulled the old incandescent fixture and installed the RV LED dome light - 10 minutes. had to us the drill for new holes and find some small fasteners in the shop.

The mounting holes of this assembly are separated by 2.5 inches vertically and 4.375 inches horizontally.

These are the best RV lights I've ever seen!. Worth the price.
I've been buying led replacement RV ceiling lights to replace incandescent car type bulbs for my RV since 2018. I have had several older RV's. Most of them burn out after about 6 months or so because of poor design early in RV led lighting.4 years later, these lights are much better design with bigger heat sinks which keep the electronic parts cooler so they don't overheat and fail. I reccomend these for your RV.


Perfect match for the lights my Palomino truck camper uses, clean bright light, 4 mount screw holes align with original holes making for a quick & easy install. I have now replaced most of the factory lights that started flashing after a week of use. These replacements have not failed yet after a 4 week trip. Happy camper!


great light, easy to install, nice switch. Just bought more to replace all incandescent fixtures in RV


Beautiful! Crisp white light (not blue!) perfect for the kitchen area where it replaced the factory incandescent light. The slim shape is also a big improvement for an under-cabinet mount. In addition, it looks sleek and stylish.

sold the trailer a few months after having the light installed. The buyer liked it and noted how unobtrusive it is.

Looks perfect can’t wait till I got time to install it


Exactly as described on the website. Nice upgrade to the original lights.


Arrived quickly and exactly what I needed. Perfect match. Easy instillation. In the beginning God said, “Let there be light.” And with etrailer, there was! You are definitely on my go to list!

Couldnt be more perfect. Probably need to order the smaller one to put in storage in case I need one or two of those.
JAMES W - 10/25/2021

Fit perfectly,while my local camper store couldn't even find one,I found it at bad ya have to replace the whole light/ was only 4 years old..will do all my light needs at etrailer

Nathan J - 08/08/2021


Great products, fast shipping and arrived safe and sound


Exact light I needed. But, came with no mounting screws. Other than that, a good buying experience.


Perfect replacement


Easy install


Great fit for my Flagstaff hardside A-Frame. Easy install & works great so far


The interior light that I purchased is exactly what I wanted. It matches my other lights perfectly. I have had nothing but good experiences dealing with etrailer for my past purchases. THANKS


Just got around to replacing the light in my camper. Works fine, nice and bright. Happy.


I received my light exactly as promised. etrailer was the only supplier I could find that perfectly matched the light I needed for my travel trailer. Great service and price!!!


Great product. Have ordered several and all work well


The R V Dome light was an identical replacement for all of the dome lights in my Georgetown R V. I searched all over and finally found the replacement lights at etrailer! I could not be more satisfied.
