Somes scoots run ac to the lights and dc for the other accessories (battery charging, choke solenoid,etc.)
A wiring schematic for your machine will tell you. The alternator output is ac, wiring going to a regulator- Rectifier (changes ac to dc) trace those out. Some alternators are split to provide ac to the ac circuits and a/c to the reg-rectifier.

We see Briggs & Stratton engines on lawn tractors doing this too. Especially if they have manual blade engagement.
Those will be very low amp unregulated dc (straight of a dc winding with another leg for a/c to run the lights.

You just need to follow the wiring to see what you have.

If the lights come on when the engine starts and dim and brighter with RPM changes , then it is AC powered by the stator as most are . My Echarm the lights come on with a turn of the key and stay the same level of brightness and never dim .

On my Magnum it has dual headlights as it has a handsome boy body like the Peace VIPs and others use . It has twin 35watt bulbs and I can see great with it . The tail bulb burned out so I replaced it with a 1157 LED which is brighter and uses less power , plus does not have a filament that burns out like a bulb . I could tell a lil diff at idle since the rear uses 5 watts on average where the brake circuit can be 25 watts . I could see the headlights dim when the brakes were applied unless I had the RPMs screaming . I had a TaoTao ATMa with a single head light , but man if was just above a candle as I could not see good enough to drive at night in the country or where there was no lights on poles .

In most cases you may go up to a bulb that is 10 watts more , but do not over 25 watts . I have read and seen in person where some tried a 55 watt bulb an it would over heat the bulb housing and put a drain on the stator and limit it being able to charge the battery up .

Keep the headlight lens clean and streak free . I use Scotts Antifog on mine like I use for my face shield , mirrors and eyeglasses . If it has haze get some of the rubbing compound made for lenses as I did on a clients van and really made an improvement after the haze was gone .

If you have the money and skills there is HID option . They look cool but the blueish hue blinds me and is worse in the rain at night to me . I have buddies that have HIDs on their cars . My scooter dealer did a HID upgrade and replaced the running lights , dash and blinkers with LEDs . LED turn signals will require a diff relay where the others you install just like a bulb with no mods needed
