Petzl Noctilight

It might be a proven strategy to blind your opponents in the face with your headlamp so you can get a sneaky glance at their cards, but that's not the nicest way to treat fellow campers in your tent.

Instead, slip your headlamp into Petzl's Noctilight and illuminate the tent so everyone can see their hand.

This secure case also protects your headlamp from impacts and turning on and off when you have it packed away.
