Where is the best place to pick up the igintion wires?

Hi,

well i'm having ago in putting some L.E.D light on the bike. i know they are not everyones cup of tea. but i'm going to put some on my gen 6 anyway to see what they look like and then decide if i'll keep them or not. My question is where is the best place to pick up the ignition wire for my lights. i've fitted a switch but don't trust the kid around my place and they will turn the lights on and drain the batt if it was hooked direct to the batt.

 

Take a long time for led's to drain one of these batterys but if you want to pick up an ignition wire, I find that the power to the brake switch is usually easiest to get to
