The 1967 Mercury Cougar featured a fully mechanical sequential turn signal system — long before modern electronics existed. ⚙️✨ A motor-driven mechanism inside the trunk rotated through multiple contacts, lighting each taillight section in perfect timed order. Using cams, relays, and analog engineering, it created the iconic flowing animation that made the Cougar instantly recognizable at night. A brilliant example of how creative mechanical innovation shaped classic automotive design. #technology #cars
