Obviously they are different sizes but I was wondering why the base model has the H1 as the high-beam and the HID equiped have the H7 as the high-beam. Does the H1 put out more light than the H7? Or vise-versa? Or does have nothing to do with light output at all. If not is it beam pattern? Reply 0 0 Kaitain View Public Profile Visit Kaitain's homepage!

Why would the car with the worst low beams also have the worst high beams and the car with the best low beams have the best high beams? If anything the HID's should have the H1's as they are already super bright. Or they should just adjust the shield so the light projects farther.

I have the HID low-beams and swapped my 50W highbeams for 100W Halogens with a nice white color. Edited to add: beware that you can smoke your wiring harness by swapping higher wattage lights for lower ones, they're illegal, and violate DOT regulations.

They are claim to be 4000k but I don't think so. It looks like they just painted a bit of color on them to filter the light comming off them to look closer to white which is decreasing their light output. I think I might start looking for a 70W or 75W bulb for those high beams. What I really want are some aircraft lights on the front to lightup those jerks that drive in the passing lane at 10 miles under the speed limit...

H7 is a more efficient bulb design than H1, and so it emits more light. The H1's high beams are on the halogen-spec headlamps, the hid-spec use H7. One good thing about the halogen spec lamps, atleast they use H7 for the low beam. You can increase wattage, but you will need a relay harness for the increased wattage draw. We dont recommend this route. You're better off going with some high output bulbs, more light without consuming more current.

What would you recommend as a more efficient H1 high beam over the Sylvania Silverstars? <edit> Or has anyone replaced their H1 highbeam with an H7? Last edited by Kaitain; Aug 9, 2005 at 07:44 PM.
