Review on 🚐 AutoEC 12V RV Ceiling Double Dome Light Fixture - 2 Color Mode Interior Lighting with ON/OFF Switch 1000Lumen for Car Trailer Camper Boat Yacht (Warm/Natural White 3000-6500K) by Brian Faxon

They have 'natural' white and warm white but no memory. When you first turn them on (either with the built in switch or with a wall switch) they start out a whiter 'natural' bright white, when you turn them off and back on quickly and quickly they become a warm white . After the shutdown, start over. So if you just want warm white you have to flip the switch twice EVERY time. Because they're so cheap I've modified them to only work with warm white, but I'm sure this will void your warranty. Let's see how long the LED lasts.
