I am hoping somebody can help me. I just bought a 2 D cell Maglite. I am trying to make it as bright as the ones that the police use but I dont know what I need to do to it. Some people tell me that I need a conversion bulb for LEDS. Would any of the following of these work or does anyone have any other suggestions. Dont want to be spending alot of money as well. Just want to make it like a police Maglite. Would any of these bulbs work?
