I think the wattage of the bulbs is a problem as well. The h7's in my newer model car are alot brighter and the wiring is more substantial.

I'm sure if you upgraded the wiring, and were able to conver to h7 bulbs, then you'd be in business.

or as said, get HID's.

Are HID's even legal to change to if you didn't have them as stock/option?
