I am thinking of buying depo headlights for a 1997 e300d. I have searched all the previous posts about how bad the light quality. It seems that unless you spend about $1,000 for replacement projectors and ballasts the lighting is not that good. If I use h7 bulbs and h1 bulbs in the fog lights, am I going to be Hellen Keller driving down the road at night? Is the light quality really that bad? Thanks for any help. Chris.
