Michael,
I agree that if you were to upgrade your headlights, that the eruos are your best bet. I have them on my 190E 16valve and love them.

A note on merely uping the wattage: I did so on a previous set of headlights (on my 240-D). I think typical wattage is 55 low and 65 high. I ran 80 low and 100 high beams! Yeah, they were really bright, but like others have mentioned, they also reflected a lot of light back into my eyes. Street signgs became beacons of light that I could see a half mile away! A bit too much.

I wear glasses and am near sighted, though not more than a typical eyeglass wearer. A trick I have learned to dramaticaly reduce glare when driving in the rain is to wear polarized sunglasses. Mine are tinted brown and are also not very dark. The difference they make when driving in hard rain is great! Just make sure:

1. they are polarized
2. they are not too dark since it obviously gets darker outside when it's raining.

Hope this helps.
