Reply to "Problems connecting 153 semaphore to OLR switch"

I tried the same thing with my OLR switches, but with a 153 block signal, and got the same results. I was hoping to use the block signals as switch direction indicators, but get the same humming sound. With all the electronics out there, there must be a work-around for this. It never occurred to me until just now, but I wonder if it has anything to do with the fact that the indicators on the OLR switch and controller are LEDs, not incandescent bulbs like on the old signals; would mixing LEDs and incandescent bulbs on the same circuit cause an issue like this?
