Hella 7" round H4 conversion
If you have any care in the world about headlight output, definitely go with this conversion. I initially ran this conversion with the 55/60w h4 hella high performance xenon blue bulbs. I now run the Osram 80/85w h4's. The xenon blues look cool and produce 4000k light, but the blue tint hinder light output and lumens. (Even the Osram are 3000k, so they are still very white). Don't waste time with silverstars and go with the osram. Check out rallylights.com if you need a place to purchase.
The light cut off is sharp (about 6ft off the ground and straight across) so high wattage bulbs are controlled even better than stock headlights and you will NOT blind other drivers.
