The Kawasaki EX300 Ninja 300 headlight bulb uses an H7 size for both high and low beam functions. The replacement chart covers vehicle production spanning 2013 to 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Kawasaki EX300 Ninja 300 uses the H7 bulb for both the high beam and low beam headlight positions across the 2013-2017 model years.
The H7 is a single-filament halogen bulb, meaning each lamp housing serves only one lighting function, which is why separate H7 bulbs are required for the high beam and low beam positions.
H7 bulbs operate on a 12-volt electrical system and draw 55 watts, figures that fall within the standard range for halogen headlight applications on motorcycles.
The H7 bulb uses a PX26d base, a two-pin bayonet-style fitting that is specific to this bulb type and is not interchangeable with other common bases such as the P43t used on H4 bulbs.
The H7 is an ECE-rated bulb, a designation that reflects compliance with European lighting regulations, and it also carries approval for use in the United States and Japan.
Because both the high beam and low beam positions share the same H7 specification, a single bulb type covers both functions, though the two housings remain physically separate installations.
