These leather bracers are set with brass studs. One of the pair also features a lens-and-dial contraption.

When you turn the dial to the left, both bracers appear normal. When you turn the dial to the middle position, a beam of light emerges from the lens, illuminating your surroundings as a bullseye lantern would.
Turning the dial to the left or back to the middle is a move action.
Four times per day, you can turn the dial to the right position as a standard action and aim the lens at a target, unleashing a searing light effect (as the spell). The dial automatically returns to the middle position after each use of this ability.
Even though only one bracer is equipped with the lens-and-dial apparatus, both must be worn for the magic to be effective.

Prerequisites: Craft Wondrous Item, searing light.
