FYI,
The ring on these bulbs is key to the headlight frame but the bulb is NOT keyed to the ring. If you remove the bulb from the ring to install the dust cover, like I did, be sure to keep track of the orientation between them. If the bulb is installed 180 degrees out, it will aim high on low beams and the sharp cutoff will be on the bottom. Once I removed the bulb, turned it 180 degrees and reinstalled, the beam aliment was identical to the H4 (9003) it replaced. No adjustment required.
Thanks for the tip on these bulbs. Picked up a pair for $33 off ebay.
