The Yamaha MT-07 high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers vehicle production years spanning 2018 to 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
The 9003 uses a P43t base, which is a three-pronged bayonet-style mount that physically locks the bulb into the housing and maintains correct filament alignment.
The 9003 operates on a 12V electrical system, which is standard for motorcycle applications.
The Yamaha MT-07 uses the 9003 bulb for both the high beam and low beam headlight positions across the 2018-2019 model years, with a single bulb type serving both functions due to its dual-filament design.
The 9003 designation is an ANSI standard classification recognized in the United States and Canada. It is electrically and mechanically equivalent to the H4 bulb used under international IEC standards, though the designations differ by market.
Because the 9003 and H4 share the same P43t base and electrical ratings, bulbs sold under either designation are generally interchangeable, though the applicable standard depends on the market of sale.
