start with the ramps. Or go from the bottom of the field. I think the sockets are just screwed in. I'd try that first unless you are doing a full blown shop job anyway. I hope you are going with all white for the GI's. Don't be tempted to use green. The ramps will make the green light where you need it. You will over saturate, if you try to use color and will not make the green stand out like it should. there is a lot of greens and blues in this game, so you could get away with cool white if you like a little more of a florescent look to things.
