Review on Super Bright T10 921 922 912 LED Bulbs - Soft White Light for 12V RV Ceiling Dome Light - RV Interior Lighting for Trailer, Camper, Boat - 600 Lumens - Pack of 10 by Ryan Koser

This fixture doesn't look like a lightbulb but looks solid enough. This isn't the easiest of installs as the socket seems to be too small and requires a lot of pressure to install. You have to swing the LED from side to side and it will slowly enter. Do not force it up or down as it may break (move sideways only). As for life, time will tell. All 10 LEDs shine very bright white. Brighter than the standard bulbs it replaced. The hood in the van had the same outlet, so I installed it. It really helps to see what's burning in your pan :) I needed 14 LEDs but there were 10 in the package. After a reasonable testing time if all goes well I will order 10 more and keep the rest for spares.
