Streamlight SL-SideSaddle USB Rechargeable Hat Light 400 Lumens

The SL-SideSaddle USB clamps to the brim or shell of a ball cap, hard hat, or safety helmet and puts 400 lumens where you are already looking. Two front LEDs give you a spot beam for distance, a flood for close work, and both together when you want the whole picture at once.

The rear facing blue taillight is the part people overlook. It makes you visible from behind on a road shoulder, in a parking lot, or walking out in the dark. Front and rear are both programmable, so you can set which modes are in the rotation instead of cycling past ones you never use. It recharges over USB, sits light enough that a cap holds it without sagging, and the hat mount is in the box. The hat is not.
