They change color with two color filters moved by a motor.

There are two separate color filters which are moved by a motor.

@Trafficlightjim We use to have a ton of those here in St. Louis, the last one (to my knowledge) was taken down about a year ago; replaced with a doghouse, just to be replaced with no turn signals at all. Such a waste of tax dollars...

yeah i found a guy who got ahold of 12 of the 3m 4 head signals. he wants 225 for each one. i talked him down to 125. debating on getting it. shipping is a cool 80 bucks

@Trafficlightjim So is it two different bulbs or just one bulb that has the ability to change colors?

How does the arrow change from green to yellow even though it is in the same lens? These 3M's always confuse me!

@suzzex There are bimodules that 3m made, however I made this one myself with two different color bulbs. The actual unit is very hard to find and when you do it is so pricey that I can not afford it.

I grew up at a intersection(that is outside Chicago)that has those 3Ms, by the way. I didn't know that they stopped making those; I also wanted one.

The only one I ever saw was at the intersection of 79th and Pulaski. I am soon going to go and try to take video of that intersection. Those are really rare.
