I have  built one of these from an electronics store in Australia
with the parts supplied in kit form and was wondering if the more
electrically minded in the group might be kind enough to tell
me what the 'bar' (as marked on the pcb) is for ?
This bar is a break in the circuit on the 12v feed side of the last
led before the circuit reaches the ic 
It is marked on the pcb with an arrow pointing to either side of the break
