Review on Powerful 5 Pack Leisure LED RV LED Ceiling Double Dome Light Fixture for Car/RV/Trailer/Camper/Boat with ON/OFF Switch Interior Lighting - DC 12V Natural White 4000-4500K, 48X2835SMD by Jeremy Keller

This is better than expected. Although the upper fits snugly, I think it's actually a positive in the long run. I used them (also a single version of this brand) to replace all the headlights on our 1990 coach. This came very close to the actual original profile. The only difference was that the hole pattern was different from the old holes by 1/4" on each side. The outer shell has been slightly enlarged over the original, but again I find that to be a plus when upgrading an old camper. Hides any discoloration lines from the previous position. I chose this brand for the variety of light shades. I was originally going to go for the warm tone of 2700k and chose the whitest option instead. I would recommend it if you have a small camper van. It really brought the room to life and made it seem bigger.I was concerned that it would feel like a hospital light, instead it would be clean and refreshing.
