I bought this on Amazon and it fits and works good:
"MZS H4 LED Headlight Bulb Single for Motorcycle,9003 HB2 Mini Conversion Kit - CREE Chips - 6500K 5000Lm Extremely Bright " $25
https://smile.amazon.com/gp/product/B07BFPQMGH/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1It has a much needed fan on the back as it gets hot in seconds when I tested it before reinstalling the plastic scooter fairing.
It is a HUGE improvement but like GrumpyOldMan said its still not quite enough for "good" car-like lighting like a friends 2014 Toyota camery with stock factory lighting.
Also, the are adjustable if the small plastic trim is removed just under the windshield as for with a screwdriver **HOWEVER** it never worked even when I first got the scooter - plastic components? Stuck in place? Also, I don't think there are any screws to adjust as the manual claims.
The best way is on the Honda ST motorcycles where you can adjust the aim while driving by turning a dial - to compensate for different stiffness of the suspension & sag due to rider weight.
