stoplight

I posted this a while back when I was dissatisfied with my headlights. I made the conversion to all 9005 bulbs (GE superblues) and have been very happy ever since.


Here is a link showing to how to modify 9005 bulbs to fit in the 9006 sockets.

http://www.bmwe34.net/E34main/Upgrade/More_light.htm

The OEM low beam 9006 bulbs and high beam 9005 bulbs are governed by DOT specifications. The low beams are allowed to produce 1000 lumens plus or minus 15% while consuming 55w and the high beams are allowed to produce 1700 lumens plus or minus 15% while consuming 65w. Any bulb that claims to be “up to 30% brighter than standard” may be, if it is operating at the top of the range (ie 1000 + 15% or 1150 lumens) as compared to a bulb operating at the bottom of the range (ie 1000 – 15% or 850 lumens).
If the high beams are allowed to produce 1700 lumens plus or minus 15% (1445-1955 lumens), in theory, good (“30% brighter”) 9005 high beam bulbs have the potential to be over twice as bright as mediocre 9006 low beam bulbs (1955 compared to 850 lumens). The nice thing is the availability, low cost, and ease of modification of the 9005 bulbs to fit the 9006 sockets.

Good luck

whoa, so ANY 9006 low beams will fit on my SC headlights?

Great, i thought there were more specs. I already have an extra HID bulbs 9006 80 watts. I think it'll be fine =)
