I thought I'd just copy in my reply to Rob when he PM'ed me regarding headlights:
Although the halogen projectors are better than halogen reflectors, they're still not that great. I've gone from having quad xenons on my ZT to halogen projectors which I currently have on my recently acquired ZT-T and had forgotten how poor the halogen headlights are, in the rain or when the road it wet it looks like I don't even have my headlights on.
If you want the best light output possible, the bi-xenon quad xenon projector upgrade I offer is the best performing option. This is where I fit an additional xenon projector to each headlight which gives you 4 x xenon dipped beams when you switch your headlights on, doubling your light output compared to standard xenons.
The next best option is the halogen quad projector option I offer, which is the same as the xenon option above except the projectors run halogen bulbs rather than xenon burners.
The next best option after that are factory xenons, followed by halogen projectors and then lastly reflector headlamps which are the worst.
Prices for my headlight upgrades are here:
