All of this sounds good to me.
Thanks for the help.
Will do that anytime soon, and post pics.
Here is the list I found after some researches for 3rd Gen:
"THIRD GEN LEDS
Reverse - 3rd Gens from 02-06 use 3057/3157, 07-08 use 921
Third Brake Light-921
Dome Light/Map Lights-578/212-2 (I found one that is MUCH brighter that fits both festoon style map lights and the dome light, it is a 4210-HP6 bulb, I used 'cool white', so as described above a '4210-CWHP6' bulb. It's like daylight in the cab.)
*Note* Some trucks also have the map light bulb listed as a 194.*
License Plate-168
Tail Lights/Brake Lights-3157 *Use a RED bulb for this*
Front Turn Signal-3157
INSTRUMENT CLUSTERS
Speedometer/gauge cluster-B8.5
(Will update with additional bulbs, HVAC, overhead console, ect)
Also, many of the miniature wedge base bulbs (921, 194, 168,) can often interchange, allowing you to use a brighter bulb, IF it will fit in the lens as far as the dimensions go concerning height, width, ect."
