It's an H7. I'm currently trying one of PIAA's higher output.
It is brighter, but they claim life will be shorter.
Osram's Hyper H7 clear 65 watt bulb (bigger H9 burner on H7 base) from their high-wattage rally and professional offroad bulb line offers 2100 lumens (brightness) and a 500 hour life, compared to:
1780 lumens, 340 hours for the Osram Night Breaker with slight blue tint.
1750 lumens, 350 hours for the Osram Silverstar (not Sylvania) also with slight blue tint.
1620 lumens, 200 hours for Philips X-treme Power H7.
