Thanks for finding that battery pack for me! The bulb is automotive type and I think it only comes in one wattage unfortunately...but I'll double-triple check. I need a light that will not be washed out by car lights on wet pavement w/o street lighting.
Is anyone else on the thread still runnning an automotive bulb solution? What sort of battery tips do you have?
