Ahh sorry that is not my ramps, that is a picture from the people selling the pop bumpers and that is a Tron LE..

I didn't drill the ramps I used little bits of sticky tape under the ramp lip to stick the light wires on, will put pictures up in the next few days... Mine are blue and yellow wires, one on each ramp, they don't change colour..

Using clear tape looks a bit shitty before you turn the machine on, once on everything lights up and you don't see it, I could clean it up a little, was thinking of drilling but the cable ties don't look any better than clear tape, maybe worse??

These are the ramp lights I bought...
