The Pontiac Vibe high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers 2003 to 2008 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9003 is an ANSI-standard dual-filament halogen bulb rated at 12 volts, with a higher-wattage filament at 60W for high beam and a lower-wattage filament at 55W for low beam, both housed within a single bulb unit.
The Pontiac Vibe uses the 9003 bulb for both high beam and low beam headlights across the 2003-2008 model years, meaning a single bulb type serves both lighting functions in each headlight assembly.
The 9003 bulb uses a P43t base, which is a standardized bayonet-style fitting. Only bulbs with this specific base type are physically compatible with the socket.
Because the 9003 is a dual-filament design, replacing it with a single-filament bulb of similar wattage would not restore both high and low beam functions from the same socket.
The 9003 designation follows ANSI standards recognized in the United States and Canada. It is electrically equivalent to the international H4 bulb, though housing and base tolerances between the two types can affect fitment depending on the fixture design.
At 60W on the high beam filament, the 9003 draws a moderate current load on the vehicle's electrical system, which is a relevant consideration when evaluating aftermarket replacements with different wattage ratings.
