Here is a set of nutz where the LED light source is at the top of the nutz pointing down. This gives the nutz a very cool glow because the nutz act like a large fiber optic and, I think, are the best looking way to light them up. 

Only one pair of LED lights can be used. The default LED color for these is WHITE. The other colors available are Red, Blue, Green, Orange, Yellow, White, Pink, or U.V. Black Light. In the comments section of the order form please indicate if you would like use a different color of LED.
Due to the way the LED’s are installed into the nutz the tall balls and stubby nutz mounting system are not available for this product.
