cheers mate,
took a bit to work out how to turn them on and off from the handset without interfering with the working of the switchblade kill switch and my idea is probs a bit complicated but works a treat to switch the power to the axillary battery's mounted to the inside of the shell.
I've got my kids here this weekend so once i get the laptop back will take some more pics of the inside of my receiver box and let you know how I've got round it
the LED's I've used are 22,000mcd 3.2v and as you can see are extremely bright!
