These cars do not like headlight upgrades. Very sensitive electrical system.
If you put an LED in it, it will burn out your windshield wiper motors and mess up other electrics.
You either need to add a custom wiring harness (called SKBOWE) or use the usual methods of cleaning the headlamps and making them work better.
Dang, they are really dim and only thing I know what to do to make them better is upgrade the bulbs
I already sanded and polished the outside of the headlight
didnt do much there, and now I am going to get bulbs and see if that makes a difference
Get halogen bulbs or whatever type it already has.
what worked for me was taking out the projector lens and removing dust from it. Was quite a thick layer on it
that might work for me too, but I just know that taking apart a headlight is hard to do
eh not really
I dont want to mess anything up and cant put it back together
but I might just risk it lol, if the new bulbs dont work
thanks btw
+1 to new bulbs of whatever is in there - they dim over time. Taking apart headlights, I’ve had success baking them in oven at its lowest setting for 5-10 minutes to soften the sealer, pull them apart, clean the inside of the lenses, put back together. Good luck!
