The Chevrolet LCF uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers vehicle production years spanning 2016 to 2019 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 Chevrolet LCF uses the 9003 bulb for both high beam and low beam headlights across the 2016-2019 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments to serve both the high and low beam functions within one housing.
The 9003 operates at 12 volts and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange and three positioning lugs that orient the bulb correctly within the headlight assembly.
The 9003 designation follows the ANSI standard used in the United States and Canada, making it distinct from the physically similar H4 bulb used under European ECE standards, despite the two types sharing comparable electrical ratings.
Because the high beam and low beam positions on the Chevrolet LCF share the same 9003 specification, a single replacement bulb type services both functions, and no separate bulb is required for each beam.
The ANSI and ECE versions of this bulb type are not considered interchangeable in all applications, as base tolerances and beam pattern certifications differ between the two standards.
