I did the old 9005 mod, and im using 9005SU Silverstar ULTRA for Ultra Night Vision - The Whitest and Brightest Halogen

 

Are there any aftermarket bulbs w/ color for the parking lights (186)? I've been looking to add a blue tint in my reflectors, but I've had no luck lately.

 

Pretty sure the parking lights are 194. Ive had some blue leds I bought from pep boys in there for about a year and a half, never burnt out!

 

Where can I get the specs for an 08 tc?

 

mostly the same, except the low beams are H11. i THINK that's the only difference
