Think you'd be better off.
Thing about lights is that a set of lights is a set of lights, but every set of roadworks is different, depending on what needs to be done, where it is, what the road system is like, how many junctions there are bla bla bla........... you could go on forever. So basically its no good setting a set of lights out that have been used on a different set of works before; that have been set up for the previous place and expect the traffic to be managed without an accident, you'd have one

But, when you get a set of lights you dont just plonk a set down at each end of the works, plug it in, turn on and think its all going to be okay.
You basically have to think of the sequence (I dont mean RED, RED/AMBER, GREEN) I mean, how long do you want the colouring sequence to last from each end, how long is the run, how long will it take the traffic to pass you, how long a time must each end be allowed to go to green after the other end has gone to red, what is the level of traffic like on that road at any given time of day; the list is endless.
Do you know how to manage the lighting sequence on a set of lights to allow for all the above mentioned criteria?
Are you accustomed with the manual needed to determine how long needs to be allowed in a lighting sequence for any given type of road?
With lights you also need cones, did you know there are regulations that need to be adhered to when using cones on the public highway? How theyre set out, spacings, sizes, allowances for traffic, pedestrians etc
And theres more

I did that cones and lights course at the Highways dept just off the M4 Swindon, I knew it was for 2 days, but couldnt understand why before I went, then knew I knew nothing once I was halfway through

if you see what I mean.
