Saskatoon optometrist Rachael Berger has noticed a rise in the number of drivers expressing concerns about their nighttime vision. Many individuals, even those young and healthy, are reporting difficulties seeing clearly while driving at night. Berger attributes this issue to the growing use of LED headlights in vehicles. She explains that our eyes’ rods activate in the dark to enhance visibility, but the sudden intense light from LED headlights can be disruptive and uncomfortable, leading to visual fatigue.
Advocates are urging both the federal government and car manufacturers to reconsider regulations and industry standards concerning bright headlights. They emphasize the importance of finding a balance that aids drivers without compromising safety for others on the road.
LED headlights, known to be up to four times brighter than traditional light sources, can trigger discomfort glare, causing unpleasant or painful sensations and visual exhaustion, according to Berger. Such intense light bursts are commonly referred to as “glare monsters.” Additionally, prolonged exposure to bright headlights from oncoming vehicles or through rearview mirrors can contribute to discomfort glare, as noted by vehicle lighting expert Daniel Stern.
Stern advocates for aligning regulations for both new and existing vehicles, emphasizing the importance of proper headlight aim adjustment. He stresses the need for stricter regulations, especially regarding the use of appropriate bulbs, cautioning against the haphazard switch to LED bulbs without considering optical compatibility.
Transport Canada last updated its headlight regulations in 2018 to incorporate new lighting technologies aimed at enhancing visibility and ensuring proper light direction. While federal regulations set safety standards for vehicles upon delivery by manufacturers, they do not extend to modifications made by dealers or vehicle owners. It is advised to refrain from replacing original bulbs with LED kits unless using parts from the original equipment manufacturer, as maintenance regulations fall under provincial jurisdiction.
David Adams, president of Global Automakers of Canada, questions the lack of restrictions on post-purchase vehicle alterations, emphasizing the need for accountability in maintaining regulatory compliance. He highlights the challenge of establishing unique Canadian regulations due to the country’s comparatively lower vehicle sales volume and the diverse range of vehicle types, such as higher-seated SUVs posing additional hurdles to standard updates.
In response to the headlight brightness issue, Vancouver and Victoria city councils have passed motions urging the federal government to address the problem. Suggestions have been made to incorporate features from European and Asian vehicles, such as auto-dimming functionalities or varied light settings for different driving conditions. The push for regulatory updates and enhanced safety standards is gaining momentum, with political leaders like Vancouver Mayor Ken Sim planning to advocate for action at national and municipal levels.
