We have collected the lighting that fits the Suzuki Gsx-R 600 U2 2001 to 2007. Depending on the version, the Gsx-R 600 U2 uses H4 or H7. Here we list the right choice for each position, along with additional lights and ballast.
The Gsx-R 600 U2 uses H4 (halogen) in the low beam.
H4 is the same bulb for low and high beam, so one pair is enough. If you choose Luxtar HERO, adjust the headlights down slightly after installation so that you do not dazzle oncoming traffic.
