This is the VestLED safety vest.  This product is designed for anyone who is looking for maximum visibility at night. The red or blue LEDs set in a reflective strip and covered with plastic. Here is  the specs.

Hottywin makes the VestLED in medium and XX large sizes and in orange and lime green colors.  All have bright red or Blue LED's.  This one  is called "lime green" (it's as much yellow as it is green) with silver reflective stripes and blue LED's.  If you're a bicyclist, road worker, traffic officer or have any other reason to be out in traffic, this is the vest for you.  It has 9 very bright blue LED's in the front and another 11 in the back.  The LED's are contained in a hard, clear plastic bubble, which is itself under a soft, clear plastic sleeve.  Behind the clear plastic is a silver reflective material.  All this is held together with a plastic mesh which makes up the vest itself.  There's 2 Velcro attachment points at the bottom to hold it tight and give some adjustment.
