not hard at all. i am pretty sure 745s use H3 for foglights, but double check in your manual. my 750 uses 9006 though.KA3AX said:Yan, I wanted to change those bulbs from the first day I got this car,
but never had time to do it. How hard is it to install them? Also which
bulbs(H3, 7 etc) do I need to get from this web site?
I hear the HID H3 retrofit is a good one and a nice match for my new 6k HID headlights. I will be having üm•nitza inc. install mine this coming week and will post my feedback (and pics) when they are installed.I'm in the process of putting HID fogs in my 7. Has anyone else done this? They use the same factory bumper and light shields but are hyper white and bright as hell.
