The KTM 620 Duke front and rear turn signal bulbs both utilize a 5008 size bulb for proper illumination. The replacement chart covers 1994 to 1997 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 bulb type specified for both the front and rear turn signals of the KTM 620 Duke across all listed model years, 1994-1997.
The 5008 is an ANSI-standardized bulb type recognized in the United States and Canada.
It operates on a 12-volt electrical system, consistent with standard automotive and motorcycle low-voltage circuits.
The 5008 uses a BA15s bayonet base, which is a single-contact bayonet mount with a 15mm collar width.
As a single-filament bulb, the 5008 serves one lighting function per socket, which aligns with dedicated turn signal applications.
The 5008 is a lower wattage variant of the 1156 bulb. While both share the BA15s base, the difference in wattage means the two types are not directly interchangeable without potential effects on circuit load and flash rate.
The uniform use of the 5008 across both front and rear positions for all four listed model years indicates a consistent socket specification throughout the 620 Duke production run covered by these records.
