Rear Light Flasher thingy....People have asked !

Discussion in 'Multistrada' started by AirCon, Oct 2, 2013.

  1. e.g. me last Saturday.
     
  2. Me. Thanks. Ordered.
     
  3. I thought you had 45 years experience!! Need an IAM course to enhance Obs?

    :biggrin:
     

  4. This is now for sale; £35 collected from London Heathrow.
    Comes with full instructions and 2nd class postage where required.
    Note you'll not have the pay the postman an extra £12 either for "import fees".
    I've now got an all in one clear rear light.
     
  5. Forgive me if I'm wrong, but I remember some while back somebody coming out with this idea, and I'm sure the constabulary said at the time it was illegal ? Have they changed the law ?
     
  6. A solid light is the legal requirement along with an E marked lens. There is a populous minority that are not able to "process" strobe, so much so that projected light becomes invisible. It can also be exasperated by certain colour blindness conditions. There are a few other reasons , but this is the one that will potentially ruin your day. There's a reason as to why our current light system and colour choices have evolved to where they are today. You could argue as to why the emergency service employ their chosen lighting given this, though I guess the accompanying siren covers most bases.
     
  7. I'm sure I don't fall into the category of those who cannot process strobe, but I do see flicker where others see solid light, e.g. LED tail lights and 50hz tv's
     
  8. there must be something wrong with me too cos all i am seeing is tosh…..

  9. Only reason I mention it as it was part of a dissertation I did into congestion many years ago at Soton university. Most of the information at the time was from the DoT if I recall. It covered thing like fonts and colour choices for road signs and target fixation with automotive lighting amongst many. Most of the data was very old though from what I remember. I don't think much has been revisited since studies from around the 60's.
     
  10. It's a construction and use thing. No recent changes in the law. This means it would fall foul should you choose to have it tested in court, similar to retro fitting hid lights to cars without level control. Some loon mp wants to ban these in read somewhere.

    On a further matter all factory fitted led lights strobe (pulse width modulation).. I never heard of anyone being able to see this. The theory is that we cannot see any flashes faster than 25hz. What is more likely is that you are seeing the interference pattern created by two strobes out of synchronisation.

    The module I'm offering is programmable allowing the rear light tto switch on off on off when suddenly the brakes are applied. Like cadence braking. IA policeman following you is more likely to think that is what you are doing, as the rear light is under computer control, not flashing every time you brake. Those who have seen it have only commented to me in a positive way.◀

  11. on off on off would suggest to me piss poor obs, anticipation and planning. i would be questioning what that driver/rider was looking at or not as the case may be….As a general rule a proper piece of planned braking takes around 3 seconds….on, two three off……

    the purpose of cadence braking is to avoid a skid and provide the tyres the option to grip so they can still steer………last time i looked it wasn't for making the rear brake light flash...

    is it sold in the uk?
     
  12. Similar lights have been a round for a while to retro fit, usually from the US, personally I like them, but they weren't legal when I looked into one, certainly my MOT tester would fail any bike with one on.
     
  13. as an aside, if it was prove to be any good or safer and a relatively cheap mod, wouldn't the powers that be want a part of it ( we are in a nanny star after all) and all vehicles be fitted with them as standard ...
     
  14. All they need to do is incorporate a g meter so the brake lights only flash under hard breaking and bingo, good idea. Quite a lot if cars do this now, it's called collision avoidance.
     
  15. I thought it was called piss poor planning…..


    However, isn't it the hazard lights that flash though……( or their real job of park any where lights)

  16. I believe there is something like that on audis as well as the brake lights. several manufacturers flash the brake lights under hard braking (it's a very fast flash, probably 5 times a second) What is disappointing is that I see that trademark rapid flash on the motorway virtually every day.
     
  17. yep its a trigger that sets off one after the other after the other………piss poor planning and follow position,…….if you are following a a correct distance…..and i don't mean that means offering up a space for someone to jump into….you can resist joining in with the broke light flash….as the amount of retardation from the queue ahead is minimal
     
  18. You're not wrong there. I can get on the motorway at j14 and get off at j20 without using brakes at all most days. I have followed colleagues leaving work who seem unable to go between breaths without braking on the same piece of road (and they wonder why I choose not to carpool)
