Don't waste bulbs on US lights...go euro
I upgraded my 300E from the US to Bosch euros. I put in the regular 55W bulbs, nothing fancy. The difference is incredible. Worth every penny. IMO, you don't need to mod anything else once you've installed the euros. They're plenty bright if aimed properly. Turn on the fog lights as well and you've got instant daylight.
If you need any advice or part nos just ask ebennz (Peter). He's the guru. Just don't ask him whether you should buy OEM or aftermarket.
