The Hyosung GT250R uses 5008 and 232 bulb sizes for both front and rear turn signal applications. The replacement chart covers 2007 through 2017 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 most frequently specified bulb across both the front and rear turn signal positions of the Hyosung GT250R, appearing across the majority of model years from 2007-2017.
The 5008 operates at 12 volts and uses a BA15s single-contact bayonet base, which is a single-filament configuration suited to dedicated turn signal circuits that require only one lighting function per bulb.
As a lower wattage variant of the 1156, the 5008 shares the same BA15s base type but draws less power, meaning the two bulbs are not directly interchangeable despite their physical similarity.
The 232 is a festoon-type bulb with an SV8.5 base, rated at 12 volts and 3 watts. Its cylindrical form factor and end-cap contacts differ fundamentally from the bayonet base of the 5008, making the two types physically incompatible with each other.
Both the 5008 and 232 are classified under ANSI standards applicable to the United States and Canada.
The front turn signal position on the Hyosung GT250R uses the 232 bulb for the 2010-2011 model years, while all other listed years for that position use the 5008.
The rear turn signal position specifies the 232 bulb exclusively for the 2013 model year, with the 5008 specified for all other listed years in that position.
The 232 and 5008 specifications appear at different model years depending on whether the front or rear position is referenced, indicating the two positions do not always share the same bulb type within a given year.
