Gustafson Lighting RV Puck Light

Need extra light on your kitchen counter for when you need to prep meals for the family? Or perhaps you need a light in the hallway so you can see where you're going when walking to the bathroom in the middle of the night? This puck light has yellow LEDs that give you a softer, accented light underneath a kitchen cabinet, in a closet, over a reading nook or chair, or in a walkway inside your RV or camper.

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.

Recessed, Bolt-On Installation is Easy

Installing Gustafson Lighting RV Puck Light

This puck light is incredibly easy to install as an upgrade or a direct replacement of your existing light. Because it has a low-profile, recessed design, you will need to cut out a 2-1/8" diameter hole if you're not directly replacing a light. To access the bolt holes, twist and pull the lens off the housing. Then, using the included screws, bolt the housing into 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). And if you want to be able to control the brightness of the light, you can connect it to a dimmer switch (not included).

The Gustafson RV recessed LED Puck Lights are an excellent addition or replacement to any RV. I replaced all my existing 10W Halogen recessed can lights with these 3W puck lights. The installation was quick and easy as they are the exact same size.
I would have giving 5-stars, but the video said the mounting screws were included and I found no screws in the shipment. I had to scramble to find some screws.


Replaces all halogen lights in my Lakota with the 3" model. Absolutely love them. Have placed a couple of dimmers on some. No longer have to deal with HOT lamps and high current draw. The light spectrum on this model is very warm and looks great!
Highly recommend to replace halogen warm white.


Exactly as advertised. Work great


Wonderful lights, we replaced old fluorescent tube type ceiling fixtures. These 3 watt led lights give much more lighting. Easy to install. Used 3 each. To replace a 2 tube
Fixture. I made a wood base that they fit into. Very happy. Makes a older motorhome come alive.


These LED lights were the perfect selection for bathroom lights on our toy hauler build. They are low profile, look really good and provide plenty of light.


Quick delivery! the light fits perfect! matches my existing lights perfectly!


If you are looking to replace a puck light in a quality A Class RV then this is most likely not the same as the manufacturers OEM light. I have a 2018 Tiffin Phaeton and the light housing (plastic) was an 1/8" to large in diameter and the plastic cover was not the same color. However the led light disc was comparable in size and brightness. So instead of returning the light I retro fitted the led light disc into the OEM metal housing and reinstalled. Worked and the light emitted was of the same intensity as the OEM light. So instead of spending $70 on an OEM replacement I was able to have a replacement and a spare led disc for later if necessary.


This light fit to replace the ones that died. I purchased 4 units two had screws two did not


These are they best replacements I've found for the faulty factory ones. And, of course, etrailer is the best.


See my review of the 4" model. Same thing different size. I have a 2014 Winnebago View that uses 3" and 4" puck lights. I ordered a couple of replacements from Winnebago parts and they were about $30 each. One of the replacements failed after about 6 months. I spotted these from etrailer and ordered both the 3" and the 4" as replacements. I've only installed the 3" but it looks great. The color is a warm white and bright. It matches the original View model almost perfectly. The cover on the etrailer is plastic and snaps on where the Winnebago is heavy glass and twists on the reflector. All and all I'm happy. Saved the glass cover in case I break on of the original glass covers.

These things work great, thinking about putting some on my sailboat.
John S - 12/04/2018


Easy replacement. Works as described.


A very nice product. Bought to replace the Puck Lights in my 07 Motorhome that were broken and used halogen bulbs. The new lights fit the existing holes in the ceiling without having to cut or drill. Just have to connect the new wires to old wires and you are done. Light uses LEDs and seems to work with a dimmer. Great price. The light with LED was less than buying an LED bulb for the old light. etrailer site was easy to use and shipping was fast, Very pleased and will buy from etrailer again.

Lights work great. I just bought 6 more to replace all the puck lights so they all match.
Harry R - 05/01/2019


This is the first time I ordered anything from, and I'm very happy with their prompt delivery of my order. I received exactly what I ordered :)


These lights are great so far. I needed to replace 12 lights with LED. I have a 2009 Winnebago Tour and these lights were exact replacements with the exception of the exterior which was a white lens, looks great. Only 3W each, old ones were 10W and cool. The old halogen were HOT! The lighting is bright.

Still working!
Ronnie - 12/20/2020


I love these. They fit perfectly where the old ones came out. Very easy installation. Much brighter than original pucks.


Used a pair of these lights to replace incandescent halogen lamps in the cabinets over a sofa. They were a perfect fit and matched the original housing dimensions down to the mounting screw holes. These lights are not only brighter than the halogen lamps but the color is very natural not blueish or too white like many LED lamps. I would guess the color temp is between 3500-4500K. I am very happy with the appearance and functionality of these lights.

After a year lights still working like new
Mike - 03/27/2020


Overall easy and quick processing. Have not installed yet, tomorrow maybe.


A perfect replacement for lights in the slide ceilings of our 2017 Heartland Bighorn 3970RD. Only place on the internet that had them. Reasonable price and multiple options for shipping, which is super convenient. SATISFIED CUSTOMER!

Light is still functioning properly. VERY SATISFIED!
Grace - 02/23/2019


Lights work really well and are a direct replacement for original lights. Only problem is that they look so good you will want to replace all the lights in the room!


Ordered 3 items: Replacement converter for RV, Replacement LED light for RV, 12" receiver extension for UTV. All shipped together and received about noon. Had the two replacement parts installed by 12:40. Everything is as expected.
Very good communication by this company on order, shipping/receiving and follow-up.


Quick delivery! Product seems good so f ar.


I have used etrailer twice in the last to
Months, both times the items have been
Exactly how they advertised them , and
Shipping was very fast , the puck lights I bought
Where exact replacements for my DRV RV
So glad I found this company , will be using
Them again for anything I need


arrived when promised. very easy to install. Bathroom light was much brighter than before. Wife said she could now see to do make up. Yes I will and have recommended to friends.. Best price I found. Even beat other stores

Product was very easy to install and we have had no problems. Enjoy the much better and brighter light
Anthony - 05/08/2019

  • Is Gustafson RV Puck Light # 277-000343 Dimmable?
    The Gustafson RV Puck Light - 3" - Recessed - 3 Watt # 277-000343 is a dimmable LED Light when used with a compatible dimmer switch. We don't carry the dimmer switch, but according to my contact at Gustafson it will be compatible. They said the switch will dictate how well it dims.

  • Replacement 3 Inch Recessed Lights For 2011 DRV Elite Suites 5th Wheel Trailer
    We don't have just the glass, but we do have the 3 inch recessed lights with LED like # 277-000343 you mentioned which would be nice replacement options for the entire fixture. We don't have a 3 inch halogen fixture option, only a 2 inch halogen option that wouldn't fit your application. My recommendation is to upgrade your fixtures to the LED fixtures that draw less power and fit your recessed cavity. I've attached videos of these options for you.

  • Spacing for the Gustafson RV Puck Light # 277-000343
    The Gustafson RV Puck Light # 277-000343 measures 200 lumens which is pretty decent for it's small size. When we tested these lights we were surprised how bright they were. If you went with one over 3-4 feet you'd have a solid amount of light in your dark galley.

  • Is Gustafson RV Puck Light Cool White?
    The Gustafson RV Puck Light # 277-000343 has a color temperature of 3,200 K, so it will fit in the cool white motif you have going in your coach. I've added a link to a video review for you to take a look at as well.

  • Can the Gustafson RV Puck Light # 277-000343 be Used to Replace QAI RSBF3NN-008 Lights
    I tried looking up info on your model light but I couldn't find anything online. The Gustafson RV Puck Light # 277-000343 has an overall diameter of 3-1/2" and it is 1-1/4" tall. The base dimensions are 2-1/8" diameter x 3/4" tall while the 3 mounting holes are spaced 2-1/4" apart on center. If you remove your current light and it has the same specs then this light will work great as a replacement! Simply wire the black wire to 12V power and then the white wire to ground and you are good...

  • Can 6 Gustafson LED Puck Lights be Wired Together on a Dimmer Switch
    You'll want to find a dimmer switch that is compatible with LED lights, but the Gustafson RV Puck Light # 277-000343 that you referenced is dimmable. Running 6 of these on one circuit is possible too. You could wire them in series as well. This means you'd run the power wire to the power wire of one light, and then connect the ground of the first light to the power of the next until all of the lights are wired in and then run the last wire back to the ground of the switch.

  • Can Dimmer be Used with Gustafson RV Puck Light # 277-000343
    The Gustafson RV Puck Light # 277-000343 can be used with a dimmer switch but the dimmer switch needs to be designed for use with LEDs. Otherwise if you use a non-LED dimmer when you go to dim the lights they might flash and make a weird noise at the dimmer switch.

  • Replacement for Gustafson # 277-000343 Puck Light That Has a Switch
    You are correct, the Gustafson # 277-000343 Puck Light does not have a power switch built into it now. The closest product we have that has a switch at the light is the Gustafson # 277000488 Surface Mount Puck Light. It's overall diameter is 3-5/8" and would probably just cover up the old lighting location when screw mounted to your ceiling.

  • Replacement Lens for RV Puck Light
    The lens # 277-000393 is the replacement for Gustafson RV Puck Light # 277-000343 and # 277-000342. I can't tell you if this is the type of light you have because RV manufacturers rarely document the specific parts that are used. If you can find a model number on the light itself it might be helpful.

  • Recommendation for 3 Inch Diameter Puck Light with Switch
    I recommend taking a look at the Interior LED Puck Light # DG52508VP from Diamond. This 3 inch diameter puck light does not feature a traditional switch, but is instead turned off and on by simply clicking/pushing on the light itself. We do not currently have a 3 inch diameter puck light available that includes a traditional switch. This is a recessed or surface mount light that provides a nice, daylight white color.

  • Options for RV Ceiling Lights That Provide More Yellow-Toned Light than LED Lights
    Typically, lights that use incandescent bulbs, rather than LED bulbs, will offer the more yellow-tinged light you are describing. We offer a number of different ceiling light styles with incandescent bulbs. If you are looking for a dome light, we offer lights such as the Trailer Dome Light with Stainless Steel Base # IL91CB. This light measures 6-7/16 inches in diameter and has a 2-wire design. If you're looking for a smaller puck light, one option is the Gustafson RV Puck Light # 277-000343....

  • Solutions for Creating Brighter Interior with Existing Gustafson Dome Lights
    Most of the Gustafson Lighting assemblies that we have available that have replaceable bulbs do use the LED # 291-GSB7038 that you referenced. You won't be able to replace this with a different bulb type as the plug-in/fitting won't install correctly. If you want to add more light to your living areas then your best option will be to either add some additional assemblies, even something like a couple small puck lights like # 277-000343 will make a big difference, or replace what you currently...

  • Recommended Puck Light For A 3" Wide x 1" Deep Cutout Hole
    The closest option we have to the # 277-000343 with a 3" W x 1" D housing dimensions would be the Glantastic LED RV Puck Light # 328-K-58L34P9 with it's 3-3/8" W x 3/4" housing dimensions. This means you would need to trim out the cutout hole an extra 3/8" for the light to properly fit. If you don't want to cut the hole larger you could just stick with the # 277-000343 since it will fit within your cutout and still cover it since the cover has a 3-1/2" diameter.

On the above 7-Way the green wire is running lights, brown is right turn and brake lights, black is 12 volt that you will run to the battery on the trailer, red is left turn/brake lights, and white is ground.
