Brake lights and dome light fuse keeps blowing

Apologies, it’s a 72 Dodge Demon.
I had to leave it in the driveway but I’ll try to check it out later when I get home. I know sometimes things can just go bad and wear out, but the only thing I’ve messed with is the flasher unit. I haven’t touched anything electrical on the column, head light switch, or under the dash. But again, I do realize things can just go bad all the sudden in these cars
