Car Exterior Lighting

Automotive exterior lighting systems including turn signals, headlights and taillights are a standard fitting in any vehicle.

HID and LED for enhanced safety and comfort

To enhance safety and comfort for drivers and passengers and enable more sophisticated body design, vehicles are increasingly equipped with high-intensity discharge lamps (HID or xenon) and light-emitting diodes (LED) in adaptive front lighting (AFL) systems. 

Smart headlamp systems require the use of high-efficiency LED drive solutions, with advanced diagnostics. Advanced systems, implementing dynamic lighting, also require headlamp leveling and bend lighting control.

Our products and solutions

ST’s automotive portfolio includes a wide selection of high- and low-side drivers for exterior lighting systems from higher power “front beam” lamps to daytime running lights (DRL) and low-power loads used by lateral and rear lights as well as advanced regulators and cost optimized microcontrollers to enable building high-efficiency and reliable lighting modules. 

ESD and battery protection devices complement the offer, to cover all design requirements.
