Honda Motorcycle CH150 Elite uses a 9003 bulb size for both high beam and low beam headlight applications. The replacement chart covers 1985 to 1987 model production 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 bulb is the sole bulb type specified for the Honda Motorcycle CH150 Elite across all listed model years and lighting positions.
The 9003 is a dual-filament halogen bulb, meaning a single unit contains two separate filaments: one rated at 60W for high beam operation and one rated at 55W for low beam operation.
This construction explains why the 9003 serves both the high beam and low beam positions on the CH150 Elite rather than requiring two distinct bulb types.
The 9003 operates on a 12V electrical system and carries the P43t base designation, which refers to the physical base type and pin configuration that must match the socket in the headlight housing.
The 9003 is classified under the ANSI standard, which governs bulb specifications in the United States and Canada, distinguishing it from the functionally similar H4 bulb used under European ECE standards.
The CH150 Elite (1985-1987) uses the 9003 specification consistently across all three model years for both beam positions, indicating no variation in headlight bulb fitment within this production range.
Although the 9003 and H4 share the same dual-filament halogen design and wattage ratings, they are governed by different standards bodies, and substitution between them warrants attention to base compatibility before installation.
