i wanna change all the lights on the interior to leds what do i need and how many for the gauges headlight switch 4x4 switch and hvac map light and door switchesi want just replacement bulbs i dont really wanna solder anything the truck is a 07 fx4
most of them are 194 bulbs, they are all t10 based. go to superbrightleds.com, personally the 5smd leds are the best. the 4x4 and head light switch are different tho. i have not found a drop in unit yet.
