Flickering or pulstating Headlights

I am going to get back into this one, lights still flicker, with all the mods. I have my instrument cluster out to look at my headlight switch and wiring. Some of the wires have some little humps in them with no discoloration. Does this mean they have bad continuity or they are getting warm? Thanks a bunch.
Might be that at some point they got hot. You say you did all of the mods, did you feed the "I" terminal of your regulator with a relay? Could be a bad ground at the regulator,the regulator itself or bad brushes in the alternator.
