i have been trying and trying and trying to build me a 20 volt rechargable light for hunting. i have the batteries and charger and every thing else i need. but i can not wire a brightness control switch. can anyone help me please. ive been told i need a rheostat switch. but i dont know what size or where to get one. or how its wired up. to buy a light like this in the stores is about 300+ dollars. i hate to pay that much for a light. thats just rediculous.
could someone tell me how to do it please.
