Hmm that’s strange.

If its H4 fitting, then yes it must be 55w type  (The headlight plastic shell inside will tell you bulb size & watts)

Then while its apart ==> Reach the headlight 3-Pin Plug ==> Get a meter “red probe inside the YELLOW pin”   and “black probe on the grey or black wire”   (ignore the white wire)  ==> You will know if 12V is actually going there, because Yellow wire is high beam

Report back and let us know.

35w bulbs use totally different fittings, so it wouldn’t go inside the headlight and they are for the 5 inch headlight from the early 200os era GV125s

Nowadays hyosung uses 7.6 inch headlight shells with H4 fittings since 2005 for the carb models
