Yamaha YW125 Zuma 125 Headlight Bulb Size

The Yamaha YW125 Zuma 125 uses an H1 bulb size for both high beam and low beam headlight applications, with 9003 as an alternative bulb size designation. The replacement chart covers vehicle production years spanning 2009 to 2021 with corresponding bulb specifications.

Additional Notes

The Yamaha YW125 Zuma 125 uses two distinct high beam bulb types across its model years: the H1 for 2016-2021 and the 9003 for 2009-2015.
The H1 is a single-filament halogen bulb operating at 12V and 55W, built to the ECE standard and recognized in Europe, the US, Japan, and other markets worldwide. It uses a P14.5s base.
The 9003 is a dual-filament halogen bulb operating at 12V with a 60W high beam filament and a 55W low beam filament. It follows the ANSI standard used in the US and Canada, and it uses a P43t base.
Because the H1 carries a single filament and the 9003 carries two filaments, the two types are not interchangeable despite both being halogen bulbs rated at 12V.
The P14.5s base of the H1 and the P43t base of the 9003 are physically different, which means a bulb of one type cannot be seated in a socket designed for the other.
For the low beam headlight, the Yamaha YW125 Zuma 125 follows the same type split: H1 for 2016-2021 and 9003 for 2009-2015.
In model years where the 9003 is specified, a single bulb serves both the high and low beam functions through its dual-filament construction, whereas H1-equipped years require a dedicated single-filament bulb for each beam position.
The low beam specification includes a 2019 entry using the H1, a year that does not appear in the high beam data.
