The Yamaha YZF-R3 headlight bulb uses an H7 size for both high beam and low beam functions. The replacement chart covers 2015 to 2018 model 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 H7 is the sole bulb type specified for the Yamaha YZF-R3 across all listed model years and positions, serving both the high beam and low beam headlight functions in the 2015-2018 model range.
The H7 is a single-filament halogen bulb, meaning each unit produces only one light output mode. Separate H7 bulbs are therefore required for the high beam and low beam circuits rather than a single dual-filament unit handling both functions.
H7 bulbs operate on a 12-volt electrical system and carry a 55-watt power rating, figures that reflect the standard halogen output level used across a wide range of road vehicles and motorcycles worldwide.
The H7 uses a PX26d base, a two-pin connector with a specific keyed orientation that prevents incorrect installation. Bulbs with a different base type are not physically compatible with H7 sockets regardless of voltage or wattage similarity.
The H7 is an ECE-rated bulb, a designation indicating compliance with the United Nations Economic Commission for Europe lighting regulations. The specification also notes approval for use in the United States and Japan, making it a globally accepted standard.
Because the same H7 specification applies to both the high beam and low beam positions across all four listed model years, a single replacement bulb type covers either headlight function on the 2015-2018 YZF-R3.
