Honest - it's just that it lasts longer! Therefore being seen is important ALL YEAR ROUND
Another misconception exists with regard to the colour i.e yellow/pink/orange etc. It's important to note that the colour does not ‘fluoresce’ at night. It needs daylight to ‘glow’. It’s function is to bring attention in DAYLIGHT.
Car and lorry drivers do not differentiate between summer and winter, if they can’t see you in winter then they won’t see you in the summer. So, if you wear a hi-visibility garment while riding out in darker months, keep wearing it throughout the summer too.
Very few people realise whether they’re horse riders, cyclists, runners, dog walkers etc; that it's the reflective piping/tape that works, not hi-vis. Reflective tape reflects the head lights, whereas hi-vis only increases visibility in dark conditions if the cars have ultra violet light in their headlights - which very few do. Items with LED lights and reflective tape are a great idea for use at night.
However, hi-vis does have its place and can help increase visibility at times when the light is dull, or during normal light where people glimpse it and slow down in preparation. It can also be useful if you're in an area with low flying aircraft - as they can see you and then try and avoid coming too close. Also, if you are unfortunate enough to have an accident whilst out hacking in the countryside, your clothing can aid the rescue and air ambulance teams to espy you and get to you quicker.
Too many people ride out in the dark thinking they are safe because their horse is wearing a hi-vis exercise sheet and they've got their bright yellow hat band on. However if these items do not have a significant amount of reflective reflective tape or panelling insitu, you will not show up any further in advance than you would by standing in car headlights (which is not advised).
The idea behind good quality hi-visibility apparel is that it has been designed to make you,
the wearer, fluoresce during
the day and reflect at night. The items are available in a myriad of fluorescent colours with added shapes and reflective
strips. This makes it easier for pedestrians and drivers to see you in most
weather conditions. But it is difficult for drivers to see you in rain (high quality tape is imperative here), dull,
foggy or sunny weather. To be seen at night by drivers you will need to wear something that is
also reflective, both on yourself
and your horse.
Did you know that a horse has the ability to camouflage itself into the shadow of the hedgerow? So, if you're riding down a tree-lined lane with no hi-vis on you, or your horse, you will be virtually invisible.
So, believe it or not, it is just as dangerous to ride out on the road in summer
