Chevrolet Express Turn Signal Flasher keeps the van's blinkers and hazard lamps pulsing at a steady rhythm, letting nearby drivers know when you plan to turn or stop in an emergency. The Turn Signal Flasher sits in the fuse block and, once the stalk is moved, it meters electrical flow so bulbs flash instead of burning steadily. Early vans relied on a thermal Turn Signal Flasher that heats a tiny bi-metal strip, the strip bends, closes the circuit to light the indicators, cools, then repeats, creating both the on-off glow and the familiar clicking sound. As lighting evolved, later Chevrolet models adopted a solid state Turn Signal Flasher that uses transistors and an internal timer to perform the same job without heat, making it reliable with low-draw LED lamps and with vehicles carrying lots of lights. Apart from their internal workings, the maximum difference is that thermal units demand a specific current while electronic units tolerate varied loads, so today's Express benefits from consistent blink speed even after bulb upgrades. In every Chevrolet Express the updated Turn Signal Flasher still makes the reassuring tick so drivers instantly know the system is active.
