Clamp-on Hardhat Flashlight Clip
This is a customizable clip based on my snap-in flashlight clip. It allows you to attach a small flashlight to your hardhat to use as a head lamp. Two screws clamp the clip securely to the brim of a hardhat.
Not all hardhats have the accessory slots, so I made this one so my slot-less brethren will still be able to see the light.
