As cyclists, we want to make ourselves as visible as possible to other road users at all times, right? So why then, do so many of us only use bike lights at night? For next week’s Ask A Stupid Question, we have the experts at Bontrager on hand to field your questions on the best use of bike lights during the day time.

Do I need lights when cycling in the day time?

According to an ongoing research partnership between Trek and Clemson University, the use of daytime running lights are linked to a 33% reduction in accidents between cyclists and cars. Not to mention that a flashing rear light apparently makes a cyclist a whopping 270% more recognizable to drivers.

With numbers like that, it’s pretty motivating to slap a light on your bike before you head out the door. So, the important questions are less about whether you need them at all… (the evidence suggests you certainly do), and more about what kind of ones you need, and in what situations they’ll work best.

Should you use a front and a rear light? How many lumens? What beam color is best? What beam shape is best? Flashing or not? Here’s your chance to ask the experts at Bontrager who design bike lights specifically for day time light conditions.

  1. I have a flashing dazzling rear light and I also use a mirror and I see the cars pass an additional 50-70 cm when I have the light activated.

    I don’t use a daytime frontlight, as I can see anything happening in front of me.

  2. I hear a lot claiming that flashing lights are not legal, or even attract drivers. Is there truth to that and if so what is the logic to a human being attracted to light?
    Also, many of the lights on the market are single LED, small point of light, similar to new LED fixtures in cars, wouldn’t a diffused, longer or bigger light be beneficial.

  3. Where I live lots of cyclists use daytime lights. As a cyclist and motorist I think about this a lot. There is no doubt that when driving a car I spot flashing lights, and then several seconds later I realise it is a cyclist. The convention here is that red is a rear light and white is a front light. For me it is a complete no-brainer. Flashing lights are the ultimate attention getter – way more useful than those absurd day-glo items of clothing that lead to nothing more than a false sense of security (although at least they absurdly seem to satisfy insurers).

  4. It won’t change distracted drivers. It more for police reports and insurance when you are asked whether you as a bike rider were wearing a helmet and had lights on with the usual blame the victim game when the driver states that they didn’t see you.

  5. What is the legal status of flashing lights? In Germany they are forbidded, what about other countries? Are flashing lights less safe than steady lights in unlit country roads? Are they counterproductive in urban areas with high densities of cyclists?

  6. I ride 99.9% of my rides on a bike trail. I HATE flashing lights. It ruins the woods. There are no cars on the bike trail. Are there off switches on that stuff?
