The original post indicated these are who knows LED units so they may or may not have built in voltage regulators designed to handle the voltage range our coaches see - from 10+ vdc to as much as 15vdc. A lot of the LED bulbs designed for use with a 120vac wall wart will fail quickly in our coach applications, some will live for a long time. The replacement bulbs from the really good suppliers will have a quality voltage regulator and those will last nearly for ever in our applications. M4LED.com was one of our Coos Bay rally sponsors. I have found their products to be universally great. Mention that you heard about them because of there sponsorship of the GMC Coos Bay rally and who knows, they might even offer a discount. I have never had one of their products fail in a GMC application.

Interesting about the diode. The LED no longer works so perhaps there was a fault with that unit. I am using the same socket and the new LED works
fine. It could be that the insulation on those tiny wires is paper thin and I will have to be more careful when handling them.
