Review on Premium 3mm PMMA Optic Fiber Cable Side Glow Kit with 12V 1.5W LED Aluminum Light Source - Ideal for Home, Car DIY (Red) by Gaurav Ansong

Some time and effort; You can really do a lot with this PMMA fiber optic. I use mine specifically with RC cars; This was the largest diameter I could find for making miniature light whips. The supplied LED is very bright; but I noticed (when disassembling) that it includes a small lens which you assumed would make the LED more focused. I have tested the light transmission through the cable with and without the lens and I personally find that the light is brighter without the small lens. Excellent value for money and quality; The outer cable shield made of PMMA is slightly detached in some places, but you won't notice anything unless you look very closely.
