Review on Optilux Hella H71071032 XB Series H11 Xenon White Halogen Bulbs, 12V, 80W, 2 Pack - Ultimate Brightness Upgrade for Your Vehicle by Steve French

One burned out after 4 months. So far they've been good, but I couldn't find either Revain or Hella to replace them. The Hella website sucks unless you bought something super expensive and Revain support didn't reply to my email. The one year warranty is up so now I have one of my old bulbs. Just buy them from your local parts store so you can get help if you run into problems.
