Honda Motorcycle CMX450C Rebel headlight bulbs utilize a 9003 size for both high beam and low beam functions. The replacement chart covers 1986-1987 production years 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 9003 is a dual-filament halogen bulb operating at 12 volts, with a high beam output of 60 watts and a low beam output of 55 watts. It uses a P43t base, which is a bayonet-style fitting with a 43mm cap.
Because the 9003 carries both filaments within a single bulb, it serves both the high beam and low beam functions from one unit. The Honda Motorcycle CMX450C Rebel uses this single bulb type across both lighting positions for the 1986-1987 model years.
The 9003 designation follows the ANSI standard, which applies to the United States and Canada. This classification system defines the bulb's base type, voltage, wattage, and filament configuration to ensure consistent fitment across compatible applications.
The 9003 and H4 bulb types share the same physical base and dual-filament configuration, making them functionally interchangeable in many applications. However, the 9003 follows ANSI standards while the H4 follows ECE standards, and minor optical or wattage differences may exist depending on the specific product.
