Vin, how do I know if mine is direct drive or still has modes (yes I know, sounds like a stupid question)? I think the factory settings has high medium and low, when I twist the head, I get from high to a medium but no low, or was I not meant to twist the head after this mod??
Low mode is sometimes lost due to a mechanical pin not protruding back in place. This is a commom Eagletac issue that I can't do anything about. Your light has more than one mode so its not direct drive for sure.
