I have a 48 with a HF predator engine.
Of course the bummer is no lighting coil.
I might have found a good solution.
On my other mini bike with a predator engine I installed a Harbor Freight off road light ($10). It has a H3 bulb. I replace the halogen bulb with a LED H3 7watt replacement ($7.00). I made a temporary wire harness and connected to my 18 volt (1.5amp hour) drill battery. A freshly recharged battery went an hour and half before the light started to dim. It was fairly bright.
I just need to replace the sealed beam bulb on my Simplex with reflector and lens setup.
