Daytime running lights (DRL)
High-efficiency LED solutions for improved daytime visibility and modern automotive design
Daytime running lights (DRL) and position lights (PO) improve vehicle visibility in daylight and low‑light environments, helping other road users recognize the vehicle earlier and more clearly. While primarily safety‑driven, these functions also contribute to a clean, distinctive, and consistent front‑end lighting signature. ams OSRAM provides efficient, uniform, and reliable LED solutions that meet global regulatory requirements and support modern automotive styling.
What are daytime running lights (DRL)?
Daytime running lights are steady‑lit front lights designed to increase a vehicle’s visibility during daytime driving. In several regions, dedicated DRL lamps — separate from the headlamps — are legally required. Beyond their safety role, DRL have become important design elements that enhance both visibility and brand recognition.
Technology overview: LEDs for DRL
Dedicated daytime running lights are typically implemented with white LEDs, although amber or yellow LEDs are permitted in some regions.
DRL LEDs can also be operated at a reduced brightness level to serve as position lights (PO), sometimes referred to as parking lights. Most vehicles feature customized DRL designs using individual LEDs, while some platforms use replaceable LED modules to support easier servicing.
Why are LEDs important for daytime running lights?
Because DRL usage significantly improves road safety—especially in Nordic regions where adoption began—energy efficiency has become an important consideration. LEDs provide high brightness at very low power consumption, which helps reduce battery load during daytime operation. For electric vehicles in particular, efficient DRL can positively influence driving range. Additionally, the small light‑emitting surface of DRL LEDs offers designers greater flexibility, allowing them to create distinctive and easily recognizable front‑end signatures.
FAQ: Below are some of the most common questions about DRL
Daytime running lights are used while driving in daylight to make the vehicle more visible. Position lights (or parking lights) mark the vehicle when parked or in very low‑light conditions. Both functions can be realized with the same LED or lamp by using different brightness levels.
DRL are often an important styling feature, so compact LED packages are valuable because they offer greater design freedom and help create unique light signatures.
Because DRL are active whenever the vehicle is running during the day, efficient LEDs help minimize power consumption. This is especially important for battery electric vehicles, where reduced lighting power contributes to extended driving range.
Often yes. The same LED type—or even the same lamp—can be used, depending on the system design, although they operate under different conditions and brightness levels.
Some manufacturers prioritize ease of repair or replacement. Replaceable LED modules—similar to traditional halogen bulb formats—allow serviceability without replacing the entire headlamp unit and simplify the supply chain.
