83. Vehicle lights

Vehicle lights are lighting and signalling devices fitted to a vehicle to help the driver see, make the vehicle visible and communicate intentions to other road users. They include dipped-beam and main-beam headlights, position lights, daytime running lights, rear lights, brake lights, direction indicators, reversing lights, fog lights and hazard warning lights.

Drivers should use the appropriate lights for the visibility, weather and traffic conditions. Lights must be kept clean and in working condition, and lights that can dazzle other road users should only be used when permitted.

What are the main types of vehicle lights?

Common vehicle lights include dipped-beam and main-beam headlights, position lights, daytime running lights, rear lights, brake lights, direction indicators, reversing lights, fog lights and hazard warning lights.

When should dipped-beam headlights be used?

Dipped-beam headlights are normally used at night and whenever visibility is poor. Unlike main beams, they are designed to illuminate the road while reducing glare for other road users.

When should main-beam headlights not be used?

Main beams should be changed to dipped beams whenever they could dazzle approaching or preceding road users. The precise requirements and distances vary between countries.
