Additional Notes

The 9003 bulb is a dual-filament halogen type operating at 12 volts, with a high-beam filament rated at 60 watts and a low-beam filament rated at 55 watts. It uses a P43t base and conforms to the ANSI standard applicable in the United States and Canada.
The KTM 200 Duke uses the 9003 bulb for its low beam headlight across the 2021 and 2023 model years.
The 9003 and H4 bulb types share the same P43t base and identical wattage ratings, making them electrically and physically equivalent. Either designation refers to the same physical component, with 9003 being the ANSI designation and H4 being the ECE designation used outside North America.
Because the 9003 houses both the high and low beam filaments within a single bulb, replacing the low beam headlight on the 200 Duke involves a bulb that also carries the high beam function.
