The Chevrolet Aveo high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production spanning 2007 to 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chevrolet Aveo uses the 9003 bulb size for both high beam and low beam headlights across the 2007-2011 model years.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both the high beam and low beam functions within one unit.
Because the 9003 handles both beam functions in the Chevrolet Aveo, the high beam and low beam headlight positions share the same bulb specification rather than requiring separate bulb types.
The 9003 operates at 12 volts and carries a wattage rating of 60W for the high beam filament and 55W for the low beam filament.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing.
The 9003 designation follows the ANSI standard as used in the United States and Canada. It is electrically and functionally equivalent to the H4 bulb used under international IEC standards, though the two designations originate from different standardization bodies.
The H4 and 9003 share the same physical base and electrical ratings, but substitution between the two should account for any regional certification requirements that may apply to a specific vehicle or market.
