Flashing LEDs - again

[Pdannyd]

Please. Turn your LED rear lights onto the steady mode or fit a second light a leave that one
on steady.

In my many years as a motorist and motorcyclist (as well as a cyclist) I have always found riders
with steady rear lights to be more visible and much easier to get a visual lock on than riders with
a flashing read light.

When you set your rear lights to flashing mode you keep disappearing and reappearing in a
distracting and confusing manner which is dangerous to only yourself. Sure, it may be eyecatching if
someone hasn't seen you but you also need something solid with which to be accurately seen.

Here's what I've found, in general: motorists don't like flashing LED rear lights because it makes
cyclists harder to see and locate though they are initially more eyecatching. Cyclists seem to think
a flashing rear light makes them more visible and telling them to leave their lights on steady mode
usually results in a barrage of abuse. Who do you believe regarding your visibility - your own
prejudices or the actual experiences of motorists?

...and I take it you don't think we're also motorists ? From personal experience, I'm sticking with
flashing things, thanks for the thought though ;-) Dave.

Tsk! That should have been **rear** light.

You're welcome. Flashing LED's to me are the same as bib shorts to the Paving Slab Fairy. Grrrrrrrr

Personally, I believe my own actual experience, as a motorisat and a cyclist.

Incidently, does it not occur to you that sometimes a cyclist might (shock!) see another cyclist,
and even were they not also a motorist would be well aware of what various lights setups look like
on teh road.

Also, as a cyclist, can I advise you to forget about your prejudices and SWITCH OFF YOUR FLAMING
FOGLIGHTS.

Our survey said:

Flashing LEDs are between three and five times more visible than a steady light of the same
brightness. Strangely, though, the DfT report to this effect has been replaced by one showing that
flashing lights are no better or worse than steady ones - but recommending that flashing ones should
be allowed anyway.

So I use both. This has the advantage of making batteries last longer, if nothing else.

I agree with you, flashing lights are fine if supported by a steady. Whilst on the subject some of
the front LED lights are near useless, on a par with cars using sidelights in poor visibility.

While some cyclists who are also motorists may like flashing rear lights I think they ought to
appeal to the wider world of motorists. SMIDSY is bad enough, don't give 'em any excuses.

I use two Cateye LED rear lights. I have one on constant, one on flashing. My front set up is an
EL200 on constant and a small Cateye flashing which I keep on the bike just in case the EL200 gives
up the ghost. I feel safer knowing that I have 2 fronts and 2 backs should 1 die on me.

And, even more radically, one or two of us might occasionally drive a car!

Do you find that a strange red mist across your field of vision obscures the pretty red lights ?

If I use a steady rear red light, then I merely blend into the sea of red lights out there. As mine
isn't as strong as the ones on cars / traffic lights and just about anything else out there, I am
less likely to be *noticed* <---- This is the important bit to me. As long as they notice me, I'm
happy. If they then choose to get upset by the method I use to attract their attention, I'm quite
happy to discuss with them, although, to date, I've never had an issue (touch wood / formica,
rather than tarmac!). I use this approach regards my front light too. Used to have a quality
halogen with rechargeables, bright but unbelievably unreliable, bulb contact problems & battery
memory problems. It really was russian roulette. Now got a new fangled blue/white led that I use in
flash mode. I *know* they've seen me, that's all that matters *to me*. ....and the battery life is
expected to be something around 300 hours. Also, as I wear hi-viz gear, the motorists have more to
focus on for tracking than just a flashing light. cheers, Dave

Maybe I shouldn't have written that last line.

Did I say that cyclists don't drive? Don't read more than I have written.

I don't have foglights or prejudices.

Don't agree at all - wee flashing red light means BIKE loud & clear nowadays. Instantly
recognisable. Constant rear red (on its own) could be anything from a reflection of a car's light on
a shop window or a puddle to an all-weather prostitute ;-) Just blends into all the other red
lights, as has been pointed out in another reply.

I use a big old Duracell filament light & a flashing LED at the back, plus little flashing LED at
the front, together with a Cateye RC200 Daylite rechargeable. Add on a sh!tload of reflective tape,
reflectors, reflective tabs on my shoes & helmet, and a Karrimor City Limits jacket which has
reflectives & is 'traffic-cone orange'. SMIDSY is not an issue - I'm the loudest thing on the road
with all that lot, especially the jacket (excellent bit of kit, BTW).

On a different tack, when I used a weedy battery filament light at the front, you could guarantee
that oncoming cars would NEVER dip their lights. Now with the Cateye (even in 7W mode), instant
dipping of headlights.

<CYNIC>Do they think I'm a motorbike at first glance, and hence a "legit road user", and therefore
dip their lights?</CYNIC> <NON-CYNIC>Do they just see a brighter front light a lot quicker (or at
all) & act accordingly / courteously?</NON-CYNIC>

There is of course always the odd w*nker who thinks that cyclists don't merit dipping lights to
avoid blinding them. Y'know all that physical effort involved in raising hand to the light stalk and
clicking it back - bit too much hard work innit? Still, it does allow me to make a
bizarrely-satisfying 'hand-shandy' gesture in their general direction, complete with verbal
confirmation. Not that they'd hear me of course...

So everyone get 2 rear lights - one constant, one flashing.

I just bought a new LED light; used it for the first time on Monday night - twentysomething miles in
the dark+drizzle, partly urban (Plymouth) but largely up here on Dartmoor. I used it in flashing
mode, along with the dynamo-powered thing and the bright yellow stripe. From the behaviour of the
motorists, I think they found me extremely visible, and I felt safer than I did on the same roads
without the flasher.

I tend to think of the yellow stripe as my best visibility-aid.

I think we're relatively fortunate in the southwest: fewer major dickheads (no grossly overpaid jobs
to attract them), and less congestion leads to better-tempered drivers.

Don't bet on them having seen you......

I think using a flashing front like this a really bad idea.

Recently I was driving the cage home in the evening about 6 pm, and raining to boot. Waiting to pull
out on a main road at a junction, into two lanes of steady moving but heavy traffic. When I had the
scary moment of almost SMIDSY-ing a cyclist (approaching from my right). Except in this case I
really hadn't seen him. I had no awareness at all that he was there until he got rather to close for
comfort and I was just preparing to pull out.

And this was when I was if anything was taking extra care because of the rain impairing the
vision through the side window. And (like most cyclists when driving I guess) was actively
looking for a cyclist.

I don't think it coincidence that he was using a front flashing light as his sole light. (and seemed
to be one of the newer ones of decent brightness, not one of these feeble jobbies.) I can only
assume that against the background of many headlights, reflections from the body work of cars etc.
in the rain and on the car window his flashing light just did not stand out at all. It was only when
he came near enough to be seen as a cyclist that I seemed to spot him.

The new LED headlights do seem pretty effective in being noticed by other road users, but not in
flashing mode.

I modified my Cateye rear LED light (normally steady) so that it maintains normal brightness 80% of
the time, and becomes twice as bright for the remaining 20%. It flashes about 1.5Hz, and has lasted
18 months (surprising, really) - I've had a lot of positive feedback, as I no longer disappear, and
it's quite eyecatching.

I'd be interested on the legality of this (although one of the positive comments was from a member
of the old William!) because the light never actually goes out.

I also put a momentary switch on my front lights, near the brake, so I can flash in daylight anyone
who doesn't appear to have seen me. That seems to work too. Quite often I will light up in the day,
especially when negotiating islands.

I'm with you. I find flashing lights on their own much more difficult to spot. I find a bright
steady one plus a slow flashing one the most noticeable.

Drivers see what they want to see. Red light = amber = go. Someone waiting at a zebra crossing = go.
Bus lane = car lane, Yellow box at junction = waiting zone, bloke on bike on footpath with front
light on full = dazzle hazzard your honour, small fine and pathetic ban please.
