The ZERO Zero S high beam and low beam headlight bulbs both utilize a 9003 bulb size. The replacement chart covers 2013 through 2018 vehicle 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 Zero S uses the 9003 bulb for both high beam and low beam headlight positions across the 2013-2018 model years covered in the specifications.
The 9003 is an ANSI-standard bulb designation recognized in the United States and Canada, making it a widely available halogen type in the North American market.
As a dual-filament bulb, the 9003 houses two separate tungsten filaments within a single glass envelope, one dedicated to high beam output and one to low beam output.
The 9003 operates at 12 volts and draws 60 watts on the high beam filament and 55 watts on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange, and this base type determines physical fitment into the headlight housing.
Because the same bulb number applies to both the high beam and low beam positions on the Zero S, a single replacement bulb type serves both functions in the headlight assembly.
The 9003 shares its filament wattage ratings and P43t base with the H4 bulb, and the two are functionally interchangeable in many applications, though the 9003 designation is specific to the ANSI classification system while H4 follows the ECE standard used in Europe.
