The Hyosung GT650 front and rear turn signal bulbs both utilize a 5008 bulb size for this motorcycle model. The replacement chart covers vehicle production spanning 2010 to 2017 with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyosung GT650 uses the 5008 bulb type across all listed model years (2010-2017) for both front and rear turn signals.
The 5008 is an ANSI-standardized bulb recognized in the US and Canadian markets, operating at 12 volts.
It is a single-filament bulb, meaning it serves one lighting function rather than combining two, such as stop and tail duties, into a single unit.
The 5008 uses a BA15s bayonet base, a single-contact fitting where the bulb locks into its socket with a twist, distinguished from double-contact variants by the single pin alignment.
The 5008 is a lower wattage variant of the 1156 bulb, sharing the same BA15s base type but drawing less power, which is a relevant factor when assessing socket and circuit compatibility.
Because the 5008 and 1156 share the same BA15s base, the 1156 is physically interchangeable in terms of fitment, though its higher wattage output differs from the factory specification for the GT650.
