Greetings
+1 on a loose ground, check around the ebrake pedal, cable and the wiring harness going to fuse block.
You could get lucky, bad grounds are always the hardest trouble to find.
First test would be push ebrake till it clicks 1 time, check lights then a couple more clicks check lights, repeat till the lights come on. All of this with your head under the dash...look and listen.
Welcome to the forum
Good luck, keep us updated.
