An Introduction to Daytime Running Lights and the Importance of Their Manufacturing — By BLIAUTO

As vehicle safety technology continues to evolve, Daytime Running Lights (DRLs) have become an indispensable part of modern automobiles. These lights are not just an aesthetic or decorative feature—they are a crucial safety component. So, what exactly are DRLs? Why are they important, and when should they be used? Today, BLIAUTO provides you with a comprehensive guide.

1. What Are Daytime Running Lights?

Daytime Running Lights are low-intensity lighting systems that automatically turn on when the vehicle is running. They are typically located at the front of the vehicle and are not designed to illuminate the road, but rather to make your car more visible to others.

Key Features:

Automatic Activation: Usually linked to engine ignition, no manual operation needed.

Non-Illuminating Purpose: Unlike low or high beams, DRLs are designed to be seen, not to see.

Modern Lighting Sources: Most DRLs use LED technology, which is both bright and energy-efficient.

2. Why is it necessary to manufacture daytime running lights?

1. Improve Visibility During Daytime

Many assume lights aren't needed in the daytime. But during cloudy weather, backlit roads, highways, or shaded urban areas, cars can become harder to detect. DRLs help oncoming vehicles, pedestrians, and other road users spot your vehicle earlier.

2. Reduce Traffic Accidents

According to studies by the European Transport Safety Council, countries that mandated DRLs since the early 2000s saw a 8–15% reduction in daytime collisions. DRLs improve visibility especially at intersections, during turns, and in bad weather.

3. Energy-Efficient and Eco-Friendly

Modern LED DRLs typically consume only 5–10W, which is over 80% more efficient than traditional low beams. They cause negligible battery drain and contribute to longer battery life.

3. Are Daytime Running Lights Important?

Absolutely.

While DRLs may seem subtle compared to airbags or brake assist systems, they play a vital role in accident prevention. They serve as a "soft protection" by increasing your vehicle’s visibility proactively.

Global Trends in Regulation:

EU: Since 2011, DRLs are mandatory on all new vehicles.

China: Not compulsory yet, but officially encouraged by national vehicle safety standards (GB 7258).

Canada/USA: Canada mandated DRLs in 1990; many U.S. vehicles now include them as standard.

4. When Should You Use Daytime Running Lights?

1. Low or Inconsistent Lighting Conditions

Cloudy or Overcast Days

  When sunlight is blocked, visibility drops. DRLs make your vehicle more noticeable in such conditions.

Early Morning or Dusk

  During times of weak ambient light, DRLs help signal your presence even if headlights are not yet necessary.

Shaded Areas, Tunnels, Underpasses

  DRLs provide consistent visual recognition in areas with sudden light shifts.

2. Complex Road Conditions

Highways or Expressways

  High-speed driving demands quick reaction time. DRLs help others gauge your distance and movement faster.

Busy Urban Intersections

  In dense traffic mixed with pedestrians and bikes, DRLs improve your vehicle’s visibility in peripheral vision.

Rural Roads or Countryside

  These roads often lack lighting infrastructure. DRLs enhance your vehicle’s detectability from a distance.

3. Special Driving Scenarios

New Drivers

  With limited experience in assessing road dynamics, DRLs provide an added safety margin.

Dark-Colored Vehicles

  Black, grey, or navy cars tend to blend with the surroundings. DRLs act as a contrast to catch attention.

Long-Distance or Continuous Driving

  Prolonged driving can dull attention. DRLs help other drivers subconsciously recognize moving vehicles.

5. When Should DRLs Not Be Used?

Although DRLs are effective in most cases, be cautious in these scenarios:

At Night: DRLs are too dim to light the road. Always switch to low or high beams.

Heavy Fog: Use fog lights or low beams instead—DRLs lack the required penetration power.

Direct Sunlight or Glare: In extreme glare, DRLs might cause visual discomfort to oncoming drivers.

6. How to Choose the Right Daytime Running Lights

If your car doesn’t come equipped with DRLs or if you're upgrading, consider the following:

Light Source: LED is the standard—energy-saving, bright, and long-lasting.

Brightness: Ensure it's bright enough to be seen but not too glaring.

Certifications: Look for compliance with ECE R87 (EU) or GB standards (China).

Mounting Position: DRLs should be 25–150 cm from the ground and symmetrically placed.

Integrated Features: Some DRLs include turn signal or width light functions—saving space and adding convenience.

7. Common FAQs About Daytime Running Lights

Q1: What’s the difference between DRLs and low beam lights?

A: DRLs are for visibility by others; low beams are for lighting your driving path at night or in low-light situations.

Q2: Can I install DRLs if my car doesn’t have them?

A: Yes. Many high-quality LED DRL kits are available. Make sure installation complies with local traffic laws.

Q3: Can I use low beams during the day instead of DRLs?

A: Technically yes, but low beams consume more power and produce unnecessary heat. DRLs are better suited for daytime use.

8. Conclusion: Small Feature, Big Safety Impact

Daytime Running Lights may seem minor, but they offer significant safety benefits by reducing accident risks in various environments. They’re an example of smart, proactive road safety.
