Jialing GY2 150 dual-sport: LED head/tail light bulbs?

[John Smallberries]

Hi all!
I'm heading to Zambia this Friday for my moto trip with my son on two Jialing 150 GY2 dual-sports. I would like to use the electrical system of the bike to charge my GPS and cell phone. I know these little bikes typically don't have much excess electrical capacity. One strategy I used on another dirt bike was to replace the head and tail light with a drop-in LED replacement. This cuts the current draw dramatically over an incandescent bulb and frees up some current for gadgets.

Does anyone know the style of head and tail light bulbs these Jialing's use? Anyone got any pics? I'm sure I can find an LED replacement for just about any near-standard bulb.

Or turn off the lights when possible
I had a large unit fitted but I'm in China
It cuts power usage down
Not a bulb but a complete inner thing
