Why not LEDs on bats, gloves!

Despite umpires standing just a few feet away from the on-strike batsman wearing an earphone to listen to whether the ball nicked the bat at the edge, despite the whole world seeing the ball take the edge, the umpire denies the wicket. How frustrating!!
During the 2014 T20 WC, I believe putting LEDs on the stumps was a very innovative idea. The umpires can now very easily and effectively judge close run-outs and stumping. Is it possible to put LEDs on bats as well which would make the bats light up at the very slightest nick of the ball? I also believe putting LEDs on gloves as well as pads is a solution for our 'blind' umpires!!
