The Daihatsu Charade high beam and low beam headlight bulbs both utilize a 9004 bulb size. The replacement chart covers vehicle production spanning 1988 to 1992.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 9004 bulb is the sole headlight bulb type listed across all model years of the Daihatsu Charade covered in these specifications, applying to both high beam and low beam functions from 1988-1992.
The 9004 is a dual-filament halogen bulb, meaning a single bulb unit contains two separate filaments: one rated at 65W for high beam output and one rated at 45W for low beam output.
Because both the high beam and low beam positions share the same 9004 bulb type, the Charade uses a single-bulb headlight system rather than a separate-bulb arrangement where distinct bulb types handle each function independently.
The 9004 operates on a 12V electrical system, which is standard for passenger vehicles of this era.
The 9004 bulb uses a P29t base, a specific connector and mounting configuration that is not interchangeable with other common halogen base types such as H4 or 9007, despite those bulbs also being dual-filament designs.
The 9004 is an ANSI-standardized bulb type recognized in the United States and Canada, meaning its electrical and physical specifications conform to a defined North American standard.
The 9004 and 9007 bulbs are frequently confused due to their similar appearance, but their wiring polarity is reversed, making them physically non-interchangeable without modification.
