Gustafson Lighting RV Light Fixtures for easy upgrades
Swap in Gustafson Lighting RV light fixtures to refresh dining, galley, or bath spaces on 12V systems. Measure your current cutout and mounting-hole spacing to match sizes, choose replaceable-bulb styles (912 or 921 T-5 wedge, or LED in warm white or cool white) or go with integrated-LED designs, and note that some options dim and use a center push-button switch.
They can be easy to install and dim just like existing lights. Confirm your RV's dimmer works with your 12V LEDs and verify ceiling screw-hole size before mounting. If a bulb or LED board doesn't lock securely into the socket, test fit before final install to avoid rework.
Yes, Gustafson Lighting fixtures can use LED bulbs, and 912 and 921 bulbs are interchangeable with the same T-5 wedge base. The 921 draws more power and burns brighter than the 912. With LED, pick the lumens and color you want, like warm white or cool white, since power draw is low.
Choose warm white if you want the new light to blend with existing warm fixtures. If you need more task light, pick a brighter option; some installs ended up brighter than the originals and worked well as reading or island lighting. LED fixtures help reduce battery draw while improving interior lighting.
Measure your current light and compare the diameter and the mounting holes center to center. Several shoppers reported Gustafson Lighting pieces as perfect replacements, but sizes can differ slightly. If the new fixture's screw holes are larger than your old hardware, plan to swap screws or use adapters to speed up install.
