I found these bike LEDs for $2.00 at an overstock store. I was able to dismantle them easily and bend the lights to aim the right direction.
I found a chunk of vinyl plastic. I was able to cut and sand them to the right shape. Also, I drilled hole for the lights.
The plastic diffuses the light nicely to get the whole disc to glow.
The whole thing fits nicely into my glove (zabana's). The on/off button face outward and can be easily pressed.
