Yesterday driving on the interstate back from New York some kid in a Toyota Highlander was following us all the way with his super blue Aftermarket HID's (they weren't halogen bulbs.. way too bright)

those were the most annoying headlights i have ever seen. We managed to lose him for a bit (my friend was driving his C230). As he caught up slowly the annoying beam of blue light came back again, we just let him pass and drove behind him instead.

I've driven in front of ML's and X5's with their appropriate xenons and they weren't annoying..
