Headlight/brake light issue

Headlights
Hey guys so I messed around with my lights again today and got them to come on for maybe a minute then, then start flashing on and off maybe 2 seconds off then come on then off etc.. ..now I'm not sure if those are highs or lows . Anyways when I hit the highbeam switch the lights go completely off and I hear a noise coming from the headlight switch never had this problem don't know what's going on.

Brake /signal light
I have no signal lights I can hear flasher by glove box go off when I hit switch In either direction . Both rear lights go off at same time and are
Very faint very frustrating .
