The Triumph Daytona 900 front turn signal bulb size measures 5008 while the rear turn signal bulb size measures 232. The replacement chart covers 1994 to 1996 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 Triumph Daytona 900 uses the 5008 bulb for its front turn signals across the 1994-1996 model years. This is an ANSI-standard bulb rated for use in the US and Canada, operating at 12V with a BA15s single-contact bayonet base.
The 5008 is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as turn signaling and braking, into a shared unit. It is a lower-wattage variant of the more widely known 1156 bulb, sharing the same BA15s base type.
Because the 5008 and 1156 share the same BA15s bayonet base, physical fitment between the two is possible, but their wattage difference means they are not direct electrical equivalents. Substituting one for the other without accounting for wattage can affect circuit load and signal behavior.
The rear turn signals on the Daytona 900 across the 1994-1996 model years use the 232 bulb, which is also an ANSI-standard type rated for the US and Canadian markets.
The 232 is a festoon-style bulb with an SV8.5 base, rated at 12V and 3W. Festoon bulbs are cylindrical in form and make contact at both ends rather than through a base socket, which is a distinct fitment type from the bayonet-style 5008 used at the front.
The front and rear turn signal positions on the Daytona 900 require two entirely different bulb types with incompatible base designs, making cross-position substitution physically impossible without modification.
