LED Dome Light Bulb Conundrum

[Stingray]

Like SpudRacer & JTSVP mentioned, you need more of a load on the circuits that have the LED's. The load resistors Spud mentioned should work. I installed LED's for the interior of my 07 Vette and they would not turn all the way off. All I had to do was wire into the factory harness one stock bulb hidden behind a panel for the rest of the LED's to work properly. That bulb gave me enough load. That is something simple you could try on your trucks.

I had a similar problem when I went to high output driving and fog lights.They would only come on IF you remembered to turn the low beams on first THEN the fogs.Any other way (turn them on in the HIGH BEAM position,turn fogs on first) would result in a LAMP OUT message light and you had to turn the truck off and start over to clear it.
