Puck light designs make swaps simple in RV ceilings, and installation can be easy. With a no switch style, match your measurements to common sizes like 3-1/2" or 4-1/2" for a snug fit in recessed or surface mounts. These can be brighter than the originals and work well in 12V setups.
Yes, they've been used as direct replacements and reported brighter than the originals. Check that your opening, depth, and hole spacing match for an easy install. These run on 12V and can swap in where your old recessed can or OEM puck was. If you're changing several, confirm one fit first, then do the rest.
Match the new light to your existing cutout and mounting. Pull the old light and measure overall diameter, cutout size, depth, and the mounting hole pattern. Confirm whether you need recessed or surface mount. Choose the color you prefer—warm white or a lower Kelvin option if you want a softer look. When the sizes match, these slide in and fit perfectly.
Connect the black wire to the 12V power wire from your existing fixture. If the light doesn't come on, reverse the polarity and you'll be up and running. Some lights arrive without wiring instructions, so double-check connections. If the lens uses a twist-lock cover, align the tabs carefully—forcing it can snap a tab.
Lens covers may not be offered separately, and you might need to replace the entire light. Measure the inside diameter of your recessed light before choosing a full replacement. If you're matching others in your RV, check the diameter and mount type so the new one looks the same.
