My left head lamp just went out and I figured "Why not just upgrade to a nicer bulb". Which is best for this car. Those same bulbs work for the high beams as well, correct. I dont know too much about lights so could someone point me in the right direction? Thanks!

 

PIAA bulbs, Hoen fogs

 

do you have a link? Also, what type of bulb does the A4 use for head lights, high beams, and fogs. thanks!

 

H7 bulbs

 

See above for bulb size.

 

If you are in a hurry to get new bulbs you could try silverstar, they are a little better than normal bulbs.

 

make sure to replace them in pairs though cuz itll look funny if you dont.

 

use only the same 35w h7 bulb specs, dont use 100w bulb or 75w becase you can carbonize the lamp, i do this and then i have to replace the etire unit

 

Yeah you can fry the wiring too, it's not designed to handle that kinda current.
