After ‘do not crash’, our one golden rule of riding a bike is that you can never have too many lights. That’s what inspired Kevr102 to design and build this auxiliary bike light for when his existing front light runs out of battery. It’s a 3D-printed enclosure for a Kitronik 5 V LED lamp kit, with the addition of a buck converter to drop the 6 V from the AA batteries down to the 5 V required by the LEDs. And as the maker notes, the square version “looks a bit like the weapon the Predator has on its shoulder”.
