Are you frustrated with the flashlight you're holding?
With this hack, a headlamp is used in lieu of the flashlight. You may now work with your hands free!
You may still utilize functional flashlights, such as the "Speed Of Light" bulbs, but you must switch to them like a tool.
Cosmetic mod flashlights allow you to change the headlamp's brightness. Simply choose the one you want and turn it on once.
