3mm 5meters/16ft PMMA Optic Fiber Cable Side Glow with 12V 1.5W LED Aluminum Illuminator Light Source for Home Car DIY (Blue)

This 3mm side glow cable was just the right size. It is brighter and costs less than the side glow cable I have bought in the past. The 1.5W illuminator lights it up great. I upgraded to a 3W illuminator and it looked amazing. It's all about the light source. Any bad reviews are because they did not use a proper light source. If you're looking for a comparison between this and el wire I would definitely go with side glow. It's superior in every way. It's brighter, more durable and comes in any color you want. This seller has gained a customer for life. Thank you Huaxi!

With a little time and effort; you can really do a lot with this PMMA fiber optic. I'm using mine specifically with RC cars; this was the largest diameter I could find for making miniature light whips. The included LED is very bright; but I noticed (upon disassembly) that it included a small lens that you would assume would make the led more focused. I tested the transmission of light through the cable with and without the lens, and personally I think it is brighter without the small lens installed.Great value for what it is; the outer shield of the pmma cable is mildly separated in some parts, but nothing you will notice unless you look very closely.

The intended use was to light up the cup holders in my car. That was going to be a tedious job so I tested it first. I wired the light to a 12volt 1.5watt transformer. Only the first 3 feet of the fiber cable lit up. I played with it, but there isn't much you can do as far as adjustments go. Okay, maybe the transformer is on the fritz. I took it outside and hooked it to my car battery. 3 feet of cable lit up. I went in the house, logged on to Amazon and set up a return. Maybe the one I got was defective, but I'm not going to take a chance and will be getting something else to light the cup holders.

Works great in low light conditions. A little brighter near illuminator, then constant color the rest of the way.

I give it 4 stars because the seller should have included some kind of instructions..but nothing. Also if the seller knows of a way to attach this cable to a wall, ceiling, etc; they should have stated how. I know about 12volt wiring so I just touched the red wire to the positive side of a 12 volt battery and the black to the negative. Wow, Beautiful bright blue. It would also have been nice to know what wire gauge size the B&R wires were.ALSO, I would not order the white color because it is so DIM was not worth installing. What a shame, Looked forward to installing it but I returned it instead. Maybe the mm size was too small.
