Best bang for the buck?

Perfect, those H4's are just what I have been looking for, more light for less money! Thanks tjts1

Ok, so next question, what wattage bulb can I use on the stock lighting harness? I have been searching but don’t have much time due to work.

H4 all the way up to 100 watts and same for the H1's. I think that is the highest power that is widely available, and I believe that is what is on my car along with independant fogs. All 6 lights on at the same time is absolutly stunning ;)

Same here. 90/100 H4 and 100w H1 on stock wiring harness with those autopal lights. I think I had to up the high beam fuse by 5a.
I'm actually thinking about upgrading to the multi surface reflector version of these lights.

130/110W H4 are out there but would suggest relaying at that wattage.

Blue bulbs = ricer crap.

BMW uses headlight relays. Unless you are planning on running 300 watt low beams, you are OK with whatever bulbs you wanna run.

I think bulb life goes down a lot once you get past 100w.

I know. Thats why you scroll down and and get the 90/100w white bulbs for $6.

Ah. I see.

BMW does use relays, but the weak point is the harness. If your sticking bigger fuses in, or getting excessive voltage drop, an additional relay with a dedicated power feed might not be a bad idea. Check control will throw a shit fit though.
