Admit it, you’ve probably never used your fog lights—or even know where to find them on the dashboard. Don’t worry; you’re not alone. Many drivers need a refresher on what their car lights do and when to use them. Here’s a concise guide to help you understand the different types of car lights and their functions.
Types of Car Lights
Dipped Headlights
Dipped headlights are your car’s most commonly used lights, brighter than sidelights but not as intense as full beams. They’re angled downward to illuminate the road ahead without dazzling other drivers.
When to Use Them: Turn on dipped headlights at night or when visibility is reduced to less than 100 meters (e.g., in bad weather). Many modern cars have automatic running lights for convenience.
Full Beam Headlights (High Beam)
Full beams provide the brightest illumination, angled higher to reveal more of the road ahead.
When to Use Them: Use full beams on dark roads with no oncoming traffic. Avoid using them when other drivers are nearby to prevent dazzling.
Fog Lights
Designed specifically for foggy or misty conditions, fog lights cut through low visibility without reflecting back like high beams. They come in front (green switch) and rear (amber switch) options.
When to Use Them: Use fog lights only when visibility drops below 100 meters—about the length of a football pitch. Turn them off in clearer conditions to avoid dazzling others.
Hazard Warning Lights
These blinking amber lights are the same as your indicators and can be activated using the dashboard’s triangle button.
When to Use Them: Use hazard lights when your vehicle is stationary and causing an obstruction, such as during a breakdown or accident. On motorways, you can also use them to warn drivers of upcoming hazards.
Sidelights (Parking Lights)
Found in the corners of your headlamp unit, sidelights are dimmer than dipped headlights and are used to make your vehicle visible in low-light conditions.
When to Use Them: The Highway Code mandates sidelights when parked on roads with speed limits over 30 mph or in foggy conditions. For roads with speed limits of 30 mph or less, sidelights aren’t required if parked in a safe, designated spot.
Tail Lights and Brake Lights
Tail lights, located at the back of the car, automatically illuminate with your headlights, while brake lights activate when you apply the brakes. Both are red.
Maintenance: Always ensure brake lights are clean and functioning. Faulty brake lights can result in penalties, including fines, points on your license, or a vehicle defect notice.
Car Headlight Bulb Types
As cars evolve, so do their lights. Modern vehicles use energy-efficient solutions, including LED and halogen bulbs. These advancements aim to enhance visibility while reducing environmental impact.
