Hmm, are all your 3Ms LED or do you have any incandescent ones.

I heard the LEDs weren't very popular due to the price and poopr worksmanship. Do these seem okay or are they aort of junky as well?

The LEDs for the 3ms are the best!!! Very Happy

The photocells in the 3M/McCain heads need to be disconnected or the LED will flicker and eventually burn out from improper voltages being forced through the digital circuit. They run fine but it eats up alot of man hours going out and rewiring the heads. 3Ms are not very service friendly which is why most are being taken out of service. They were also expensive which is one reason why 3M got out of the traffic business

Who makes these, we have ElectroTech and the greens flicker as they get older. And yes the PC-dimmers are bypassed.
