Illuminated 'Cats Eyes'

Just driven down the A1(M) at night. Southbound, just north of Scots Corner, I looked in the mirror and saw the 'Cats Eyes' between the lanes glaring back at me, with nothing to light them up. I then noticed that the Cats Eyes ahead were lit too, not just reflecting my headlights. They looked good, bright obviously, like LED centreline lights, but they only were for a mile or two. Never seen them before. Are they a new coming thing? Seems a bit complex and expensive (not too mention the need for a power sorce, unless they somehow srlf-charge) and can't imagine they'll last that long. What's wrong with, well, Cats Eyes?

I remember seeing the same effect from cats eyes about 15 years ago in Hampshire. I don't recall exactly where it was, but an old friend was showing them to me as her company was developing them. I don't know how those ones worked exactly, but she said the light came from your car's headlamps and were reflected back somehow so that you could see them in your rearview mirror.

I think the A24 from Dorking going south had these maybe 15+ years ago when I lived there.

"In a trial costing 390,000, the Highways Agency has replaced more than 3,300 traditional cat’s eyes (or studs as it refers to them) with solar-powered ones on the section of the M6 between J17 and J18 in Cheshire. The result is brighter and clearer illumination so drivers can better differentiate between lanes, slip roads and the hard shoulder when they are travelling at night or in poor weather; especially on unlit sections of motorway.

Traditional cat’s eyes rely on reflective strips being lit by headlights. The new solar-powered ones also have this strip, but their brightness is boosted by an internal battery, kept topped up by daylight. They contain sensors so they come on automatically when it gets dark."

There were experimental solar powered cats eyes fitted on sections of the A11 on the Suffolk Norfolk border. They didn't last that long because people kept nicking them for garden lights or whatever!

Thanks for this thread. I'm still laughing about it.

And wondering why we're so effing far behind the times.

We basically have non-reflective "Bott's Dots" here, and after a few years, most of them come loose.

In a few places, we have the reflective things dug into the pavement, but after a few years of heavy traffic, they don't reflect so good anymore. And they never reflect light when covered with rain or snow -- it diffuses your headlight beams before they even get to the reflectors.

In many areas, the highway folks "tank track" the edge of the traffic lanes, deeply grooving the pavement, so that if you wander off the beaten path, your steering wheel hums and your sunglasses rattle on the dashboard.

It seems that that isn't enough, because folks still plow through guard rails and find innocent trees to punish with their badly driven vehicles.

Cheers!

Lit cats eyes were installed years ago on the A23 on a series of bends near Hickstead. I remember noticing them in the rear view mirror. The road layout has changed now.

Deffo remember seeing them on a local B road hereabouts nearly 20 years ago, apparently a trial. Since then I have notied them at odd places nationwide sporadically. I guess councils are prepared to allocate money for trials, but not for wholesale swap-outs.

Same here, they were installed as a trial around an A road junction around 15 years ago. They started to fail pretty quickly, within a few weeks many of them were not working. Eventually they were ripped out and replaced with standard cat's eyes.

IIRC, the ones I saw were activated by the light from an oncoming car's headlights, so they only turned on when a car triggered them, then stayed on for a short time afterwards.

It must be a dangerous job crouching down in the middle of the road switching each one on (and off) each evening/morning.

Solar powered reflectors have been around for about 25 years; we had some on the airfield at Farnborough just after MOD flying moved out. Unfortunately, like all solar powered lights, the batterys fail eventually.

I like these ones, turn on and off with the traffic lights. You can also get ice detection studs which flash blue when black ice is detected and radio linked Ines which can be turned red by traffic control when there is an accident up ahead.

All of the edge lighting (don't know about centreline lighting) at my home port is solar powered.

In Lincolnshire on one unclassified road they had a brilliant idea to put temperature sensitive warning posts on particularly dangerous ice prone bend. Every spring when danger of ice had past they would be removed until the following winter, this went on for three years until people who you t call pikies had removed the lot.

The self illuminating road marking lights (cats' eye replacements) trialled on some UK roads were invented by an ex-fireman from the Newark (UK) area.

A certain police ASU was given a set to trial as markers for their helipad, which at that time was an unlit field. Unfortunately, they were far from powerful enough to be of any use.

I hated the blue ones on the A1. They seemed to strobe at my brain's looking frequency.


My car looks at the road ahead and goes into stick-shaker mode if it thinks I'm about to cross a white line. I thought duff paint would fool it, but it really seems to cope with a well worn line..

It can be turned on and off by one's thumb.

Sadly, concentrating on my multi-function steering wheel has caused me to crash twenty-seven times - and that's just going to the shops a hundred yards away.

I seem to remember hearing (when he died) that the inventor of the original cats' eyes received a 1 cent royalty for every one sold. Made him a millionaire several times over.

Where the's muck the's brass. - Peter Shaw, their inventor, was a Yorkshireman.

Cents hadn't been invented at that time, how about 1 penny ?
