Hey Lost, I've got a problem with my map and Extraordinary told me I should ask you, so.. here we go.

I'm working on a new surf map, and in the spawn there will be some light effects. It's hard to explain so i will link to this screenyL

The things I pointed with the red arrows are big light ledges where spotlights are put on.
I want to create light effects with this. For example the upper two ones will light up, then those below them etc etc.
I decided to use logic_relays which will be enabled and disabled but I can't get that done.
What is the best way to create those effects?
