I am thinking about having all my car interior map lights, dome lights, step courtesy lights changed to White LEDs.
I have checked the Osram Guide but still a little bit confused about the bulb sizes I need. Can someone who has did this help me out, thanks a bunch!

 

there is thread called LED swap made by member called crab I guess.

if u didnt find it just inform me

 

Go here -----> LED Vehicle Bulb Finder

put in your make/model/year, it tells you all the bulb sized needed for an LED conversion. I just did mine. They ship in like 2 days.
