New to me boat has a toggle switch to power Fuel guage, Volt meter and Tach in dash. Keep forgeting to turn it off and have run down cranking battery a couple of times. Went to radio Shack and found 12V sealed led lamp and installed between tach and speedo, wired to toggle to be on with switch in on position. Now maybe even a Geezer can remember to turn off switch:yikesAttachment 80369
