That was always a classic 70s car problem. My Cortinas used to do that. Indicators on and brake lights used to flash. Opened up and were like a sauna from poor sealing and of course a rusted poor earth so the lights earthed through the next best/available route, another bulb. 5 mins with wet and dry and all was fixed.
Enjoy yourself, it's later than you think!
