Lighting

Modern automotive lighting has evolved beyond simple illumination to become a key element of vehicle safety and design, demanding highly integrated, efficient, and reliable electronic control for everything from adaptive headlamps to sophisticated interior ambient lighting.

Allegro offers a broad portfolio of robust and highly integrated LED drivers for any interior or exterior application. For advanced functions like dynamic headlamp leveling and bending, our stepper motor drivers and Hall-effect position sensors provide the precise control and feedback required for these safety-critical systems.

Our technology enables smarter, safer, and more efficient lighting systems that improve driver visibility, enable new ADAS features, and allow for greater design freedom.
