The KTM 1290 Super Duke R uses 5008 bulb size for both front and rear turn signal applications. The replacement chart covers 2017 to 2018 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 KTM 1290 Super Duke R across all listed positions and years, covering both front and rear turn signals for the 2017-2018 model years.
The 5008 is an ANSI-standardized bulb recognized in the US and Canadian markets, operating on a 12-volt electrical system.
It uses a BA15s bayonet base, which is a single-contact fitting where the bulb locks into the socket with a twist after two small pins on the base engage their corresponding slots.
The 5008 is a single-filament bulb, meaning it serves one lighting function only, which is consistent with its application in dedicated turn signal housings rather than combination stop/turn assemblies.
The 5008 is a lower wattage variant of the 1156 bulb. Both share the BA15s base, but their wattage ratings differ, making them physically interchangeable in the socket while not being electrically equivalent.
Because the 5008 and 1156 share the same BA15s base type, substituting a 1156 in a circuit calibrated for the 5008 would alter the current draw, which can affect turn signal flash rate on vehicles using load-sensitive flasher relays.
