Headlight question

[MChick]

OK, at 27,000 miles, one of my headlights finally went away. Rather than paying BMW lots of $$ for their branded bulbs, what aftermarket bulb do I use in the ST?

The maintenance manual call for H4 55w for the low beam, and H4 60W for the high beam. Are these available aftermarket?

Any auto store has them,,Napa and so on,,,,,

[MChick]

Cool. Thanks, just wasn't sure.

[10ovr]

One thing to remember,Dont touch the glass with your fingers,The oil from your fingers well shorten the life of the bulb,,,

[MChick]

That much I know. I'm going to replace both today, since one is out, the other is probably soon to follow.

[10ovr]

Dont forget the 200 mile test ride to make sure all is OK,,

[MChick]

Yeah, a little over 200 miles, up to Legget, down hwy 1 to Mendocino, then Comptche Rd. back home to Navarro. Lots of twisties to make sure the bulbs are in correctly, too.

Powerbulbs.com............ Philips X-Treme Power H4, great bulbs, much brighter. I just installed the H7's.

I've found the stock bulbs at the BMW dealership to be either the standard issue Sylvania or Phllips at so near the same price as an auto parts store that its not worth the difference to go one place over another. There are three auto parts stores near my home so that's where I go.

Also consider this if you're thinking of the "super", "ultra", whatever bulbs. I bought a set of Sylvania's that were top of the line (and priced that way). They appeared nice and bright at mile 0. At around mile 2000, then 3000, they were very very dark (as in burned out). Brightness can affect longevity.
