one downside to a light on your head is if you try to speak to anybody you blind them. you can have a second light on the handlebar using same logic - light head is on the bar and battery is elsewhere on the frame. lights with integrated battery are heavy and tend to slide and not maintain where you aimed them. the handlebar light can illuminate the ground directly in front of the bike while the helmet light should be the more expensive one and can illuminate further and be aimed in different directions. @Prince Aleph @HERMETICVM
