headlight upgrades
#2
Lots of headlight upgrade options out there but many are crappy Chinese parts. I'm in the process of upgrading the halogens in my 2010 E350 with XenonPro upgrades. Not sure what headlights and/or bulbs you have but https://www.xenonpro.com/ sells both LED and Xexon HID upgrades. The LED upgrades work best in a reflector housing, whereas the Xenon HIDs work best in a projector housing. The site has lots of other helpful info. as well.
