It is the stalk-mounted control that the driver uses to activate the left or right turn signals. Notably, this version of the switch does not include a self-canceling feature, meaning the driver must manually return it to the off position after completing a turn. It is commonly replaced when the original switch becomes worn, broken, or the electrical contacts fail, causing intermittent or non-functional turn signals.
