Triumph Sprint Headlight Bulb Size

Triumph Sprint headlight bulbs utilize H7 and 9003 bulb sizes for both high and low beam applications. The replacement chart covers vehicle production spanning 1996 to 2012 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.

Additional Notes

The two bulb types specified across the Triumph Sprint headlight fitment data are the H7 and the 9003, both halogen and both rated at 12 volts.
The H7 is a single-filament halogen bulb operating at 55 watts and uses a PX26d base. It conforms to ECE standards, which govern lighting equipment across Europe and much of the world, though it also carries approval in the United States and Japan.
The 9003 is a dual-filament halogen bulb with a P43t base, rated at 60 watts on the high beam filament and 55 watts on the low beam filament. It follows the ANSI standard used in the United States and Canada.
Because the H7 carries a single filament and the 9003 carries two, the two types are not interchangeable. Their base configurations, PX26d versus P43t, are physically incompatible with each other's housings.
For the Triumph Sprint, both the high beam and low beam positions use the same bulb type within any given model year, meaning a single bulb type covers both functions for each year listed.
The 9003 type is specified for both headlight positions across the 1996-2006 model years of the Triumph Sprint.
The H7 type is specified for both headlight positions across the 2007-2012 model years, reflecting a change in bulb standard from the earlier 9003 fitment.
The base change from P43t to PX26d between the 9003 and H7 generations means that housings designed for one type will not physically accept the other without modification.
