View media item 4936 rd filter gel. yes its burnt, you have to bear in mind these lights must be 7 or 8 years old.
View media item 4937 red one working but hanging by its flex so you can see it.
any joy with the question? why do those in picture 1 (this post) look familiar?
The reason is they are short drainage pipes
The bottom half (length ways) is cut off to make them look like a traffic light cowl, the ridged part stops them falling through the hole in the mdf and they are glued in place.
The controls are in the shed.
if you look carefully, the lights joydivision link to and mine are made by the same people (vellerman) but mine are not intended to be traffic lights
so its who ever wants to make it's choice which kit they opt for, either will need adapting.(relays adding, which is very easy)
I would say the one i used is easiest, since its bigger and has less components (it does need assembly and soldering)
Please do bear in mind the lights are about 7 - 8 years old
