Well I have tried to buy the brightest bulb for each size that I can find without upping the wattage.
Fullbeam:
H1 - Philips Vision Plus 50%
Main headlights (dipped):
H7 - Philips X-treme 80%
Side lights:
W5W - PHILIPS BLUEVISION W5W (got these free with the H7's is there anything brighter then these??)
Fog lights:
H3 - Philips Vision Plus 50% (these ones seem to be pretty rare)
I looked at the Philips DiamondVision bulbs, they will look bright when your looking at the car, but don't project light as much as the X-treme and VisionPlus series, which you will see more with.
If anyone knows of brighter bulbs with same wattage, please post
