Yes, given the fact that the lights starting coming on after you hit the tracks, I'd check the wiring. It really shouldn't make a difference, unless someone has tampered with the wiring at one point, and maybe misrouted it. Connectors and wiring should all stay intact regardless of what kind of bump you hit. I'd still have the check done, just so you know and don't waste any time running in circles, and you can tell exactly which wheel to look at.
