Parking lights are essential car lights that keep your vehicle visible when stationary, especially in low-light or high-speed areas. Also called sidelights, they help prevent accidents by alerting other drivers to your presence. Following UK legal rules ensures safety, avoids fines, and keeps your car road-ready.

What Are Parking Lights?
These low-intensity lights are installed at the front and rear of your vehicle. Typically, the front lights are white or amber, and the rear lights are red. Unlike headlights, their purpose is to make your car noticeable to other road users when stationary, particularly in dim conditions.
Legal Requirements in the UK
Under Rule 249 of the Highway Code, vehicles must display these lights when parked on a road or lay-by with a speed limit above 30 mph. This requirement helps improve visibility and reduce accidents.
On roads with a speed limit of 30 mph or below, you don’t need to use them if:
- Your vehicle is at least 10 metres from any junction
- It’s parked close to the kerb and facing traffic flow
- It’s in a recognised parking space or lay-by
When to Use Parking Lights
Use them in these situations:
- Nighttime Parking: On roads with speed limits over 30 mph
- Dimly Lit Areas: Poorly lit streets or areas without street lighting
- Legal Compliance: To follow traffic regulations and avoid fines
These lights are not for driving; they only indicate a stationary vehicle.
Common Misconceptions
- Not for Driving: Using them while moving can confuse other drivers and isn’t compliant with the law
- Not a Headlight Substitute: They don’t provide enough illumination for driving at night
- Limited Visibility in Daylight: Some vehicles’ lights are hard to see during bright conditions

How to Activate Parking Lights
- Locate the headlight control switch, usually on the dashboard or steering column
- Turn it to the first position to activate the lights
- Confirm that both front and rear indicators are illuminated
Always check your car’s manual for specific instructions.
Benefits
- Enhanced Visibility: Makes your vehicle noticeable to others
- Legal Compliance: Helps avoid fines for improper parking
- Safety: Indicates a stationary vehicle, reducing accident risk
