Mystery circuit board

[Les Bird]

Having started a long overdue tidy up, I came across this component. I can't for the life of me remember what it's for. Any suggestions?

You might need to take a better photo showing the bottom right corner of the board without the shadow, there appears to be a black IC there but it's hard to tell. It would also help if the red component were visible in greater detail. Whatever it is, it's a six-channel something, and what I thought at first were six yellow Leds along the right hand edge are not, because there are tiny Leds visible amongst the wires coming out of the vicinity of the yellow items. is there no identifying number underneath?

A photo of the underside of the board might help determine the inter-component connections too, which would help in understanding what its for.

A slightly better picture. There was a label underneath but all the wording has faded. It is a Busch product and I suspect it may be for flashing lights at roadworks

I did wonder that. 2x TRs, a flip-flop; red cube is a relay; yellow blobs are connectors; caps for timing. Possibly?

Could be for a set of temporary traffic lights, Red/Yellow/Green and x2 ?
