Daytime Running Lights Explained

Welcome to our blog, where we will delve into the topic of daytime running lights, also known as DRLs. These lights are intended for use during the day, as the name suggests. With the increasing prevalence of DRLs on modern vehicles, it's evident that they offer numerous advantages.

In this blog, GB Vehicle Leasing will discuss the benefits of using DRLs and address some common queries about these vital safety components. Whether you're a new driver interested in learning about DRLs or a seasoned motorist seeking to stay up to date with the latest safety technology, this blog is for you. So, let's delve into the topic and learn all there is to know about daytime running lights!

What are daytime running lights?

Daytime running lights are a set of lights on a vehicle that are designed to improve visibility during daylight hours. DRLs can take several forms, including LED lights, halogen bulbs, and even strips of lights.

While they were first introduced in the 1970s, their widespread adoption has been a more recent development. In the UK, DRLs were not widely implemented until the early 2000s, when several car manufacturers began offering them as a standard or optional feature on their vehicles.

How do daytime running lights work?

Daytime running lights work by illuminating the front of a vehicle during daylight hours. They are typically wired to turn on automatically as soon as the ignition is switched on and turn off when the vehicle's headlights are switched on.

The specific way that DRLs work can vary depending on the design of the vehicle. However, most modern DRLs use light-emitting diodes (LEDs) as their light source. When the DRLs are switched on, an electrical current is passed through the LEDs, causing them to emit light. The light produced by the LEDs is then directed through a lens or reflector and out of the front of the vehicle.

What's the difference between daytime running lights and headlights?

The main difference between DRLs and headlights is the purpose they serve and when they are used. DRLs are designed to improve visibility during the day and are used when the vehicle is in motion during daylight hours. They are intended to make a vehicle more visible to other drivers and help prevent accidents by increasing awareness of the presence of the vehicle on the road.

Headlights, on the other hand, are designed to illuminate the road ahead of a vehicle during periods of low visibility, such as at night or in adverse weather conditions. They are typically more powerful than DRLs and are used to illuminate the road ahead to make it easier for the driver to see obstacles and other vehicles.

Additionally, headlights are typically controlled by the driver and can be turned on or off manually. DRLs, on the other hand, are usually automatic and are designed to turn on as soon as the vehicle is started and turn off when the headlights are switched on.

Do all new cars have daytime running lights?

In many countries, new cars are required by law to be equipped with daytime running lights (DRLs). However, this is not a universal requirement, and the regulations can vary depending on the country or region. For example, in the European Union, all new passenger cars and small delivery vans manufactured after February 2011 must be equipped with DRLs. In Canada, all new cars have been required to have DRLs since 1990.

It's worth noting that even if a country or region does not require new cars to have DRLs, many automakers still choose to include them as a standard feature on their vehicles. This is because DRLs have been shown to improve visibility and reduce the risk of accidents, so many automakers consider them an important safety feature that adds value to their vehicles. Overall, while not all new cars are required to have DRLs, they are becoming increasingly common.

Should daytime running lights always be on?

Daytime running lights are designed to be on whenever the vehicle is in motion during daylight hours. While it may be tempting to turn off DRLs to save energy or reduce wear on the lights, it is important to keep them on at all times when driving during the day. These are an important safety feature that can help prevent accidents and improve road safety.

How do I turn on daytime running lights?

As previously mentioned, in most modern vehicles, daytime running lights (DRLs) are automatically turned on when the vehicle is started and turn off when the headlights are turned on. This means that in most cases, you don't need to do anything to turn on DRLs - they should be on by default whenever the vehicle is in motion during daylight hours. If for some reason your DRLs are not turning on automatically, or if you want to check that they are working properly, you can consult your vehicle's owner's manual for specific instructions on how to turn them on.

Do daytime running lights need replacing?

Yes, like all other bulbs in a vehicle, daytime running lights may need replacing over time as they can burn out due to usage. Typically, daytime running lights have a longer lifespan than other types of bulbs, but they still have a limited lifespan. It's recommended to check the condition of the daytime running lights during regular vehicle maintenance and replace them as needed to ensure optimal visibility and safety on the road.
