It enables the driver to signal left or right turns and lane changes by completing the electrical circuit to the turn signal lights. The switch is typically replaced when it fails to activate the signals, becomes intermittent, or when the self-canceling mechanism no longer works. The VSI 918Y998 is often specified as a replacement for Western Star, Mack, and Volvo truck models.
