Found good place to look for LEDs for interior Map / Dome Lights.
I recently bought and installed Blue LEDs and found them on 2 different sites. www.NS-FX.com www.Motoringmax.com
I found both of these web sites through EBAY MOTORS and search truck parts, interior lighting... Also narrow search down by selecting Ford F-150... Very happy with Dome Lights, still waiting on Map Lights...
I have the same truck as you with a bulb out on the overhead map light. I tried getting my fingers in between the console and the head liner to pull it down but was afraid of breaking the console. You mention a video, do you have a link to it? I would like to see it. Thanks
