The Suzuki Motorcycle RMX450Z uses an H8 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2017 to 2019 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H8 is a single-filament halogen bulb operating at 12 volts and 35 watts, fitted with a PGJ19-1 base. Single-filament construction means the bulb serves one lighting function per unit rather than combining two functions in one envelope.
The H8 bulb type is built to ECE standards, the regulatory framework used across Europe and much of the world, and also carries approval for use in the United States.
The Suzuki Motorcycle RMX450Z uses the H8 bulb in both its high beam and low beam headlight positions, meaning both circuits draw on the same bulb type despite serving distinct lighting functions.
Because the high beam and low beam positions share the same H8 specification, a single bulb type covers both sockets on the vehicle.
The low beam headlight on the RMX450Z carries the H8 specification across the 2017-2019 model years, while the high beam headlight carries the same specification for 2018-2019.
The PGJ19-1 base is a keyed locating base specific to the H8 and a small number of related halogen types. Bulbs with physically similar but differently keyed bases in the PGJ19 family, such as the PGJ19-2 used by the H11, are not interchangeable with H8 sockets despite their outward resemblance.
