I would like to replace my 5 reading lamps and 3 dome lamps with LED. All 8 have the same bulb but I don't see a number, just 12v 10w. They have round bases like car or trailer brake lights. 2 pins to hold them in the sockets and 2 contact posts. I want some bulbs that project straight for reading and some that flood the compartment. Has anyone done theirs already?
