Traffic Signal modifications

[fesser]

I have an old traffic signal in my shop that has the bulbs set up to blink intermittently. They blink faster as they warm up and then they all end up pretty much lit up most of the time which doesn't have the same effect. I seem to remember toys that reacted to sound/music and was pondering whether the traffic signal could be wired to respond/react to music. I didn't search this forum this time because I am pretty sure this question doesn't come up too frequently.

There are plenty of different types of sound activated lights (mostly for 'disco' applications) on Amazon. I'm sure you could adapt something to fit your traffic signal.

Hadn't thought of Amazon. I was thinking it would be more complicated. Thanks

Think of the traffic light set as three individual lamps.

All you need to do is power them from a rotating supply - whether that be digital circuit board or PLC, or relays.

Just remember to use a relay/relays - solid state or contact in between any small controller and the lamps.

But what would make them want to fire off? Just on a cycle that doesn't change?

Not sure what you have ...but I did up a couple with red, orange and green lamps a few years ago. I just made the lamps flash on and off in sequence.

Got it. I am hoping for something that is reactive to sound. Still need to check for what Photon440 suggested. Thanks

Do you have a Radio Shack or similar electronics outlet store nearby?

There's probably a cheap kit you can build.
I know we can get the likes of a Knightrider sequencing kit down here.....there'll be something that you're looking for.

I saw some listed on Amazon. (probably e bay too) "Stoplight controller" will get you there. About $25.

Thanks. Just went the Amazon route.
