Low beam light went out on my 2009 MB E320 and before buy a new one I decided to remove the old one to buy similar bulb or replace both of them.
The old one removed from the car was an Osram 64210S 12V 55W H7U made in Germany as engraved on the body of the bulb.
Not paying too much attention to the Wattage I bought two Hella H7 12V 100W
Should I use these bulbs of 100W to replace my old ones of 55W ?
Will be there any problem using these lights?
Thanks

I'd imagine running a 100W bulb in place of a 55W bulb will blow a fuse. Not to mention all the oncoming traffic you'll be blinding. Go back and get the correct bulb.

MB wiring in the modern era leaves much to be desired. 100w bulbs might melt insulation and connectors which is more work to repair than a blown fuse.

Thanks for your reply. Two other replies have almost the same answer.

You will melt the wires at the bulb socket and the fuse will blow if you're lucky. Otherwise, expect to ruin your housing. I've done this before with a pair of 100w H3 that I did not pay attention to when ordering.

Thanks for your help. It was very useful.

It's not just modern era cars, headlight wiring on the US lights even back in the 80s was pretty piss poor.

That being said, I'd recommend going back to 55w or look for some LED bulbs if you want something brighter. I can vouch for The Retrofit Source (they're only 5 minutes from my house, never had a bad experience), they sell H7 LEDs by Morimoto and Profile Performance.
