Genuine Buick Rainier Turn Signal Flasher

The Buick Rainier Turn Signal Flasher makes sure that your SUV's blinker and hazard lights flash at a consistent rate. This ensures that other drivers notice every change in lane or roadside halt. The Turn Signal Flasher is installed in the fuse box where it receives the stalk's electrical command and opens and closes the circuit in rapid succession for the blink effect. The early models employed a thermal Turn Signal Flasher that utilized heat to bend a bi-metal strip, causing the contacts to click together and then cool down and separate, repeating the process. Subsequent iterations transitioned to a solid state Turn Signal Flasher, replacing the mechanical movement with an electronic relay governed by a timing chip, ensuring consistent illumination even with low-draw LED bulbs. Unlike the older thermal design, the new solid state Turn Signal Flasher weighs less, lasts longer, and is accurate regardless of bulb load. This is a useful upgrade when a Buick owner retrofits modern lighting on a Rainier built with the older thermal design that fits the same socket. Changing the flasher module on your Buick Rainier is an inexpensive and easy job. If your SUV is having problems with the blinkers failing or flashing erratically, simply swap in a compatible module and every driver will signal properly again.
