Cub Cadet Challenger 500/700/750 Turn Signal Bulb Size
Cub Cadet Challenger 500/700/750 models utilize 5008 bulb size for both front and rear turn signal applications. The replacement chart covers 2017 through 2019 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 5008 is the sole bulb type specified for the Cub Cadet Challenger 500/700/750 across all listed model years and positions, covering both front and rear turn signals for 2017-2019.
The 5008 is an ANSI-standardized bulb recognized in the United States and Canada, operating on a 12-volt electrical system.
The 5008 uses a BA15s bayonet base, which is a single-contact fitting that locks into the socket with a twist.
As a single-filament bulb, the 5008 serves one lighting function per socket, meaning it does not combine turn signal and brake or running light duties within the same bulb.
The 5008 is a lower-wattage variant of the 1156 bulb. While both share the BA15s bayonet base, the wattage difference means the two types are not electrically interchangeable without potential effects on circuit load and turn signal flash rate.
