I have (8) TIR3s controlled by a Sho-Me rotary flasher. The knob on the controller broke off and now I can't change the flash pattern. All of the other flashers I have seen are for less then (8) lightheads. I'm not looking to spend a lot of cash on this so should I just replace the Sho-Me with an identical one or am I missing a different flasher that's available? BTW, this is for an internal bar if that makes a difference.
