Vehicle headlights have significantly increased in brightness over the years, primarily due to advancements in technology. Kartikeya Murari, a professor at the Schulich School of Engineering at the University of Calgary, notes that the transition from incandescent lamps to halogen and now to light-emitting diodes (LEDs) has changed the landscape of automotive lighting. LEDs emit white light with varying amounts of red, blue, and green, and their smaller size contributes to the perception of increased brightness. However, this brightness can create glare, affecting other road users. In response, Transport Canada is conducting a national survey to gather Canadians' experiences with headlight glare, focusing on nighttime driving conditions and potential solutions. Murari emphasizes the necessity for updated regulations to keep pace with these technological changes, suggesting that standards should account for factors like color temperature. He warns that the increased brightness of headlights can lead to dangerous situations on the road, as drivers may struggle to cope with the glare.
