We love do it yourself projects and found a great mod idea for a lighted Tenga 3D. Not much skills is needed other than drilling a hole and a little gluing.
The middle rod of Tenga 3D can be taken off as pictured here.

Drill through the hole (Always take care when using any tools and wear protection) and glue a simple tube light like the one pictured below to replace the original rod.

The end effect is very nice.
