i am working on cyberpunk inspired mantis blades, and i have recently bought some light blue plexiglass to get the glowing blue blade effect. i am stuck trying to figure how to get the edge of the blade to glow because i would like to buy leds that are not highly intensive and not very noticeable. i plan to run the led lights on a 3.7v lipo battery so if i can get any suggestions or feedback, that would be awesome!
