2010 E350 head light H7 white bulb?
It's just hard installing into the driver side. I removed a bracket with 2-10mm plastic nut to gain more room.
I can definitely see better at night.
Philips X-Treme Power H7s are my favorite Halogen H7 though. They are a tiny bit whiter, but also much brighter. You can get them on Ebay. They are made in Germany.
