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.

I bought these lights because the original started failing. I've had no problems with these and the color and brightness is perfect.

I have a 2020 MPG 33RV. After about a year the original ceiling lights started to fail one after another by blinking and half the row of LEDs not working. I bought a few of these lights just to see if they are designed any better. The old lights has a half inch by 34 heatsink, yours is a heatsink covering the entire fixture. Just to be sure I removed the circuit board and found little heatsink compound so I added a little more because most early versions of LED lights would overheat and fail as evident by the brow discoloration under the driver chip. After several months of perfect operation and cool running, I bought enough to replace all my ceiling lights. I have not had any problems and the are as bright as when I bought them. I am completely satisfied and would recommend them to all RVers and boats. One thing I would like to recommend is you give brightness in lumins and whiteness color like home led lamps from cool white, to warm white and K rating for geeks like me so people who buy them know how bright, or not they will be. I like a more white light on my dining table as I use it also as my office. I am completely satisfied with your product and would like to thank you for engineering an led lamp that actually works. I have been buying led lights since around 2015 and most were so poorly designed that Ive thrown out so many early attempts at led lighting. I would recommend that if you can, advertise in rv and boating magazines with some of your reviews. Have a good day, and thanks again for a solid product. You can shorten this review for printing if you like, most people arent as technical as I am.

We are very happy with the Gustafson 12V LED dome light for our RV. It was shipped out promptly and we got it in just a couple of days. It was easy to install and is working great above the dinette tablet.

The dome light was exactly what I needed worked perfect We will definitely be using you again. You have a very satisfied customer. Than you !!

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.

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

The light is still working fine. As a matter of fact, I use it more often than I thought I would in lieu of other countertop lights at night.

More great service and good prices from etrailer!



by:

I’ve ordered a couple of things from each etrailer now, and they continue to surprise me with superb quality. I purchased LED interior lights and a nice exterior porch light for an old trailer and the upgrades have really improved. The old giggle box shipping was fast and their service was very trouble. Free would definitely order from them again.

Have been replacing one of my original camper lights each yr as they die. So far these replacements are working fine and match my original mount holes. puts out a clean bright white light. Using bullet wire connectors make for an easy future replacement when needed

Nice low profile and easy to install. I just wish it came with the mounting hardware and wire nuts.

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

Exact match. Easy to replace

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.

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.

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.



by:

Excellent replacement lights.



by:

It was an exact match with other lights for my trailer. It seems like a more durable product than the original. It was easy to install.



by:

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!

  • Recommended Replacement For A Sunlink Lighting Star Series # RSBF-4N-008 Dome Light
    From what I can find of the Sunlink Lighting Star Series RSBF-4N-008 it is a 10"x 4" dome light with a button. Our closest option to this is the Gustafson RV LED Dome Light w/ Button # 277-000492. This light is slightly smaller at 9" x 4" so it's not an exact replacement but is is very similar in design. This 12v light has a simple two wire installation that can easily replace your old Sunlink light.

  • How To Remove The Translucent Dome To Access The Mounting Holes On Item # 277-000492
    I can see where that would be frustrating. The dome cover and white ring on the Gustafson RV LED Dome Light Item # 277-000492 can be removed together. Right along the bottom edge of the white cover there are two small slots on each side. The white ring snaps into those slots. The dome can be removed by simply taking something flat like a paint scrape and sliding it in between one of the long edges of the white ring and the dome and lightly separating them. The dome has a tab that slides...

  • Compatibility of Gustafson RV LED Dome Light 277-000492 With 2018 Georgetown 36B Class A Motorhome
    If the existing lamps in your Georgetown Class A motorhome are 12 volt (which they should be), the Gustafson # 277-000492 would work great for you. If you're asking if these would be an exact replacement for the existing lamps in your motorhome, it would be very difficult to determine that. The RV industry doesn't operate like the auto industry where every 2018 Ford F150 with the 5.0L engine would use the same part number spark plug wires. The OEM equipment used in a given RV or motorhome...

    The Gustafson Interior light part # 277-000492 certainly could be used as a replacement assembly for what you have now but it might be slightly different. Either way it will fit pretty easily but you might have to drill new mounting holes. The mounting holes of this assembly are separated by 2-1/2 inches vertically and 4-3/8 inches horizontally.

  • Why isn't LED Strip of Gustafson RV LED Dome Light # 277-000492 Replaceable
    The LED strip of the Gustafson RV LED Dome Light # 277-000492 that you referenced is not replaceable as it's permanently fixed to the base of the light and even if it wasn't the panel is not a standard type of replaceable light. Also LEDs rarely fail so if you are worried that you'd install it and be stuck with a broken assembly you should note that failure of the light would be incredibly unlikely.

  • Recommended Replacement RV LED Dome Light With Switch
    Depending on the type of light you have whether incandescent or LED you could have a variety of reasons for why your current light isn't working correctly. Incandescent bulbs have a typical lifespan of 750 - 2,000 hours while LED's have a typical lifespan of 50,000 hours. Voltage drops typically are the cause of flicker so if you have other appliances or items running on the same circuit they could be causing the flicker. Loose connections could also be the cause, which would either be...

  • How Does Lens of Gustafson 12V LED RV Dome Light # 277-000492 Come Off
    The outer ring of the Gustafson 12V LED RV Dome Light # 277-000492 comes off by prying off. There are four tabs around the ring that need to be pried off. Two on top and two on the bottom. You'd need to use a small slot screwdriver to pry them off.

  • What Color Of Light Does the Gustafson RV LED Dome Light with Button Produce
    The Gustafson RV LED Dome Light w/ Button part # 277-000492 produces a soft white light which will be around 2000K to 3000K on the Kelvin Scale. That said, the manufacturer does not specify this but you can use the video I have attached for you to get a better feel for the color.

  • Will Gustafson RV LED Dome Light Survive Power Fluctuations in RV
    The Gustafson RV LED Dome Light # 277-000492 that you referenced is designed specifically for RV/trailer applications so it will absolutely survive the common voltage fluctuations/spikes it will go through in this setting. Just by its nature being an LED instead of an incandescent bulb it's also going to last much longer and require much less power to illuminate. I have attached a short video review that you can check out as well.

  • Recommended Replacement Dome Light For A 1990 Sea Ray Express Cruiser
    The closest options that we currently offer for an overhead light would be the Optronics 12V LED RV Dome Light - 10-5/16" Long x 4-3/16" Wide # RVILL34 and Gustafson 12V LED RV Dome Light - 9-1/4" Long x 3-3/4" Wide # 277-000492. Both run off of 12v DC power, which should be how the lights in your 1990 Sea Ray Express Cruiser should be powered. Both come with a switch to turn the lights on and off and are a surface mount design. If I were to choose between the two I would have to go with...

  • LaSalle Bristol Interior RV LED Light Was Flickering But Now Doesnt Work
    It could be a number of reasons why your LaSalle Bristol RV LED Dome Light # 344410PCDS010008RT, which is no longer offered from the manufacturer, started flickering and now does not work. On average LED bulbs typically have a lifespan of 50,000 hours and there may be a chance that it is burnt out. Voltage drops also will cause flicker, so if you have multiple appliances running at once, it may cause your lights to flicker. Finally, I would check the wiring to the unit itself. You can...

    Sorry to hear your Gustafson RV LED Dome Light w/ Button # 277-000492 aren't working properly! Since the LED strip in # 277-000492 is permanent to the unit, the only way to get a new LED strip is to purchase an entire assembly, unfortunately. But, before you do that, if you haven't already I recommend checking your ground connections for these lights as this is the most common reason LEDs don't function as intended. I know it's not ideal, but if you've verified that all of your lights...
