Technical Deep Dive

Projection turn signals work by using a combination of cameras, sensors, and LED projectors to detect the vehicle’s surroundings and project turn signal indicators onto the road. The system consists of several key components, including:

• A camera module that detects the vehicle’s surroundings and sends data to the control unit
• A control unit that processes the data and controls the LED projectors
• LED projectors that project the turn signal indicators onto the road Common failure points in projection turn signal systems include:
• Faulty camera modules or sensors
• Software glitches or calibration issues
• LED projector failures or misalignment
