R6 LED rear light problem

Hey guys having an issue with my project. i am actually doing a 1991 fzr genesis but i have put a kawasaki zx6r rear end onto it and i am currently fitting an R6 LED tail light with built in idicators. the driving lamp and brake lights work fine. however the indicators are cause me some issues. if i have the entire lamp wired up whenever i put the indicators on it makes the indicator work correctly on the required side at the proper rate however it make the brake/driving lights flash also. i.e when the indicator lights all over lights cut out and then they come on between flashes.this happens when indicating in either direction. the strangest thing is if you unplug one indicator the other one works fine and all tail lights stay on while indicating.i dont get it at all and the lights came with no instructions.any suggestions people? indicator relay? earth problem? duff back light?
