The Hyosung TE450S uses H7 bulb size for both high beam and low beam headlight applications. The replacement chart covers 2008 to 2010 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 H7 is a single-filament halogen bulb operating at 12 volts and 55 watts, fitted with a PX26d base, which is a two-pin bayonet-style connector designed to lock the bulb securely into the housing.
The H7 bulb is rated under the ECE standard, meaning it meets European and international regulatory requirements, and it also holds approval for use in the United States and Japan.
The Hyosung TE450S uses the H7 bulb size for both the high beam and low beam headlight positions across the 2008-2010 model years.
Because the high beam and low beam positions share the same H7 specification, the TE450S headlight system relies on separate bulbs for each function rather than a dual-filament unit handling both beams from a single lamp.
The PX26d base is not universally interchangeable with other common halogen bases such as H1, H4, or H11, so substituting a bulb with a different base type would result in an incompatible fit in the TE450S headlight housing.
