i actually changed my lights and bought some phillips one for about 30 bucks each, beacuse my lights use to be yellow and dull. by changing them, it made it very noticable and you could tell the difference at night. i own a 97 teg. and had the same prob. may be try changing the lights, that might work. but if you change them, get good ones. the one i got are just legal. but there are two models above the ones i got. try looking at any Autobahn shop.
Good luck, hope i ve helped.
