I've recently replaced the headlights on my Jonway YY250T and would like to share the experience.
I have previously worked on replacing the bulbs on my scooter with LED bulbs. I've replaced the Taillight, License Plate Light, Running Lights, and Instrument Cluster lights with LEDs that are very bright but use less power than the original incandescent bulbs. This left me with a surplus on the charging system to use toward "Other Upgrades". In this case, brighter headlights! The factory 35W BA20D-style headlight bulbs are poor. Brightness is low which reduces visibility to other drivers, while the reduced brightness makes morning/evening/night driving impossible. One of my bulbs had the low-beam element broken and it needed to be replaced anyway. I purchased a pair of replacement compatible bulbs from an overseas dealer, but they had manufacturing defects that rendered them useless for this application.
On tearing the front end down previously, I noted that the headlight buckets were keyed for automotive style H4 bulbs. Keeping this in mind, I researched online and found that H4 bulbs could be purchased in 35W, 45W, and much higher wattages. After calculating the power I had available from the LED bulb replacements, I selected the 45W, also partially due to my concern that any higher might melt the plastics.
Parts - 45W H4 bulb, H4 plugs to splice into the wiring harness, and factory bulb for comparison:

H4 bulb mounted in same socket:
Splicing H4 plug into factory wiring harness with heat shrink ready to cover the joint:

The finished product:
I haven't driven in low-light conditions yet to observe a difference, but can verify that the beam is much brighter than with the factory bulbs when projected against the garage wall. The beam is focused perfectly for both high and low beams. The only issue is that my scooter doesn't follow normal headlight wiring color code and now the high and low are reversed. Not an issue, I'll live with it until I tear the front end down again. Overall, I'm happy so far; I want to take it for a ride around the neighborhood after dark sometime to see just how much difference it makes.
