Red Light On Helmet with Rucksack -- Invisible

Out tonight for 35 or so miles, light on helmet, seatpost (times 2 in case one fails), rear stay and one around the ankle.

None of them cost the earth but you'd have to have one hell of an excuse to miss (or should that be hit) me...

Remember that legally the requirement is that a light is attached to the bike, between 350mm and 1500mm from the ground, centrally or offside (right hand side).

No issue with having additional lights, but for legal purposes you're riding without a light if you don't meet that standard with at least one light.

Need to have a reflector too- mudguard mounted ones are ideal.

What about 'man-bun' lights, pretty sure there is a need for those too!

The one I see most often is people on mountain bikes with rear mudguards and seat post mounted lights, where the mudguard obscures the light from directly behind. I find other people's lack of spatial awareness puzzling sometimes!

I'm just about to launch a kickstarter for my new cycling specific beard light range "BeardyLight"  - works on everything from a "Castaway" full beard to designer stubble. 

Only £89.99 for 25 lumens of fashionable beard lighting magic! Produced in the UK. Order today! Or visit our boutique shop in Shoreditch.

Beware just being anywhere near Donald Trump.  He sucks all light and hope out of the world.

Commuting by bike in London I see riders in winter with the tiniest of rear lights, those £5 single LED jobs, barely visible at the best of times, even with new batteries. Wearing black. Good luck being seen on a busy road through a wet windscreen. Not that I expect motorists to pay any attention of course, but jeez.

On a slightly more serious note, in reasonably heavy traffic, lights at rucksac level, or higher up make the cyclist look further up the road than they actually are, compared to other cyclists. It's an odd optical illusion that I've seen several times.

Also, the combination of dark clothes and only a single rear light with no reflectives in lots of city traffic can make it hard to work out where the cyclist is, especially on rainy nights when there are lots of distracting reflections etc. I hate driving at night in traffic for this reason.

If you have a very long beard, then it can obscure your front light.  More of a problem around the trendy parts of east London.

Don't forget cyclists (generally in the city) with a red light on their seatpost, who forget that a longer coat  will completely obscure it.

And people who have a red light in the pocket of their rucksack, but then put a Hump cover or similar over it, so they end up with a diffuse glow like ET's belly...

Ditto some saddle bags.
