LED modified rear insert for Halo Helmet

Note this part has now been added directly to base model Size A Helmet - consider this thing deprecated.

This is a LED mount for the rear insert in this full size A Halo Helmet.

This insert takes two 5mm Leds into the bottom of the piece.

The body is deeper to take the leds and diffuse the light slightly.
