Spinlock Lume On Life Jacket illumination light

Currently exclusive to Force 4 Chandlery. These unique, flashing LED lights illuminate the inflated lifejacket bladder, using it as a diffuser, to dramatically increase visibility and aid location.

I have a 5D, bought in 2017. I can confirm that Lume-on most definitely ISN'T a standard feature.

The Lume-On lights are a seperate product.
