5.5.1. Overview

The Flashing Light Manager controls the flashing of the turn indicators and hazard lights based on driver inputs and vehicle states. It processes requests from the turn indicator stalk, hazard switch, central locking, and emergency braking to determine when the left and right turn indicators should be activated. The component also detects faults in the turn indicator lamps.

5.5.2. Functions

	Title	Description
1	Turn Indicator Control	Controls flashing of the left and right turn indicators based on requests from the turn indicator stalk and steering wheel angle. Supports temporary and permanent flashing modes.
2	Hazard Light Control	Activates both left and right turn indicators simultaneously when the hazard light switch is pressed. Overrides turn indicator requests.
3	Emergency Stop Signal	Automatically activates both turn indicators at an increased frequency during emergency braking situations above a defined vehicle speed threshold.
4	Central Lock Flashing	Flashes the turn indicators when the vehicle is locked or unlocked via the central locking system, with different flash durations for valid and invalid lock states.
5	Crash Event Flashing	Activates the turn indicators when a crash event is detected.
6	Intrusion Alarm Flashing	Flashes the turn indicators at a defined frequency when the intrusion alarm is triggered.
7	Turn Indicator Fault Detection	Detects faults in the turn indicator lamps based on feedback and activates a faster flash frequency to alert the driver.
