Hi - Are you sure this is the proper bulb type? I can't find the base listing or type listed by Kymco and haven't pulled the front apart to check the base and size. As for pumping the wattage up ... these small bikes / scooters have pretty small batteries, alternators and wattage output. If the battery gets low on a ride, you could have a real problem getting it going again.
The 35w / 35w bulb seems more than adequate for the speed this bike is capable of. If you want more light / visibility, you might want to look into putting some low drain (wattage use) bulbs in the original turn signal holders (the ones built into the body).
Has anyone got the actual size and bulb number for the headlights?
Even Candlepower doesn't list it ...
