Smile 08 X3 High Beam Halogen Upgrade

Wasn't happy with the high beams so I installed 2 PIAA H-218 H7's that burn at 4000K. Result is much "whiter" beam with 20-30% longer reach; they're expensive (~$75 a pair) but well worth the results. The process is a real PITA and the vague instructions in the owner's manual for doing so are laughable. Removing the originals is no problem once you shrink your hands down to half-size, remove the plastic housing cover, press down on the bulb socket and remove the socket/bulb assembly. I had to remove the w/s washer tank and air intake duct/air filter top to gain enough clearance for the job.
The super PITA is installing the new bulb assembly into the headlight housing cause you can't see what you're doing since your hand obstructs a decent view so carefully eyeball the thing first then proceed cautiously being certain that the tang on the bulb flange is exactly at 12 o'clock high, otherwise the bulb flange will not snap home in the headlight housing .
Words of caution:
1. Wear safety goggles since bulbs are under high pressure and are very fragile.
2. Don't touch the bulb with bare skin.
3. Expect to skin some knuckles in the process; no room for gloves.

Cheers,
bobkap

Just a waste of money--they look cool but provide no more usable light than stock bulbs

http://www.danielsternlighting.com/t...good/good.html

I installed a set of the Ostram silverstars in my Z4--they work good but anytime you replace older ( mine is a '04) bulbs with new it will be brighter as headlight bulbs loose output over time. I read the tests run by "Daniel Stern Lighting" that did a real world test with many bulbs and the stock halogens outpreformed most all others especially the PIAA brand. Something to keep in mind when they burn out.

dug,
Did my own test with L stock and R PIAA, didn't have a photometer but the H-218's definitely threw more light on the target 500' distant.
Regarding longevity, will just have to wait and see and keep the oem bulbs at hand.

Just like rolling tubes in my high-fi equipment.
