The Hyosung GT650R uses a 5008 bulb size for both front and rear turn signal applications. The replacement chart covers vehicle production spanning 2010 to 2017.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Hyosung GT650R uses the 5008 bulb type for both front and rear turn signals across all model years from 2010-2017.
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 only, which is consistent with dedicated turn signal applications.
The 5008 uses a BA15s bayonet base, a single-contact mount where the bulb is inserted and twisted to lock into place.
The 5008 is a lower wattage variant of the 1156 bulb. While both share the BA15s base, the wattage difference means the two types are not direct equivalents and substituting one for the other may affect circuit load and signal timing.
Because the front and rear turn signal positions share the same bulb type, a single 5008 specification applies to all four turn signal housings on the GT650R.
