To the OP - ignore the reprobates above, they're just jealous
Does your car have Xenon lights? If so, you can't connect the strobing kit to the headlights as it won't work with main beam. The main beam is actually a mirror/lens that flips up and down to control the light throw.
You'd have to connect the strobing kit to the fog lights - there should be a separate fuse for that though. I'll see if I can dig out which fuse number it is exactly.
Good luck, and remember to post a detailed video when it's all done
