Should cyclists use daytime running lights? + 13 of the best front and rear daytime cycling lights

51% of readers surveyed on Twitter say yes to using daytime cycling lights - do you agree? We speak to See.Sense, Exposure and Specialized about daytime cycling lights

You need front and rear lights for cycling in the dark, but do you also need to use lights in the daytime? We look at the argument for using lights during the daytime and round up a bunch of front and rear lights to consider if you do want to increase your visibility.

13 of the best daytime running lights for 2021

It may not have escaped your attention that all new cars sold in the UK legally have to have daytime front lights. So should cyclists also be looking to boost their visibility when cycling in the daytime with front and rear lights? In a recent survey of 500 readers on Twitter, 52% said they do want daytime lights. It perhaps wasn't the result we were expecting.

To meet this demand, there are a growing number of bike brands marketing lights with daytime running modes, but what does this actually mean and are they any different to lights designed for nighttime cycling?

Exposure Lights has added a new Day Bright mode to its front and rear lights this winter. And it is more than just a flashing mode says Exposure’s Mark Swift. “The DayBright pulse pattern is the most noticeable to ensure it is recognised at distance on rural roads and also enable the light to cut through the noise of the urban town or city traffic and road distractions within daylight hours," he says.

“As the pulse pattern is not regular, once seen DayBright stays highlighted by the brain's receivers and ensures the cyclist is noticed,” adds Mark.

Why would a cyclist want to use lights during the daytime? Surely there’s no need when it’s light?

“Why not!” says Specialized’s William Watt. “Beyond smart responsible riding, visibility on the road is quite simply the most important investment a rider can make in their safety, particularly in a congested urban environment where every road user has a multitude of distractions. Daytime lights give the rider that extra layer of visibility on the road, particularly for that notorious black spot on the near side of traffic.”

It's not always bright and sunny during a typical UK winter day though. It’s often murky, drab and almost dark. Daytime lights can be used in these conditions says Exposure's Mark to help make cyclists stand out in changing light conditions and when “cycling in cities between building or country road in and out of tree cover where the sun cuts through the gaps but is then eclipsed by an obstacle the drivers eyes can sometimes not adjust fast enough. DayBright ensures the cyclist is spotted.”

It’s a stance that is backed up by See.Sense, a company that launched an intelligent daylight back in 2013 and every light since has had a daytime focus. “Daylight visibility has been really important to us right from the start,” the company tells “When you consider that 80% of cycling accidents happen during the day, attracting attention to other road users as early as possible during these times is really quite crucial. Think about modern cars, they have their lights running almost any time you see them on the road. Why shouldn't it be the same, if not even more important for cyclists?”

That 80% figure that See.Sense refers to is based on evidence compiled by ROAP and you can read more facts and figures about the number of cyclists injured or killed in accidents here.

The argument for using daytime lights is starting to gather pace, but has anyone actually carried out a detailed survey to assess the impact of cyclists running daytime lights? Handily, just such a survey exists. It was conducted in Denmark in 2004/05 with 3,845 cyclists and concluded that those cyclists with permanent running lights recorded a 19% lower incident rate than a control group not using lights.

“The study shows that use of permanent bicycle running lights reduces the occurrence of multiparty accidents involving cyclists significantly,” the controlled experiment concluded. You can read that paper here.

So should we all start using daytime lights then? See.Sense recommends using flashing lights to help attract attention sooner. “When you have lights that flash brightly from both front and rear can help alert drivers sooner than a solid light, reducing risks out on the road,” the company tell us.
