  1. I am an A-level product design student, for my my major project i have decided to design and make
    indicators to put on a bicycle. My initial idea is to put a device with indicators and a brake light
    on the back of the bicycle connected to the seat post so people travvelling behind the cyclist can
    see what the cyclist intends to do and then put a tube with a amber light on the end fixed onto
    either end of the handlebars so people aproaching from the front can see if the cyclist intends to
    turn. If anyone has any ideas on this please post a reply .... it can be possitive ... negative ...
    doesnt matter all replys will be useful

  2. Since your hands need to be ready to activate the brakes at all times, my thought was to have such
    lights activated by squeezing the brake handle in the direction you are going to turn. There is a
    small gap where you cam move the brake handle without activating the brake. The handle bar end would
    not be a good place for dropped handlebars or sweep back handlebars (because the end points
    backward). (There are red blinking lights you can buy and put in these holes). Perhaps something on
    the head tube? Perhaps a good lighting material wouod be the polybrite.compolybrite.com material. A
    sliver of soft, pliable, light diffusing plastic strip. LEDs at the end emit light into the strip
    and it is released along the length of the strip.

    There is at least one product on the market that activates a brake light when the rear brake lever
    is pulled. I have never seen this in use. I'd think you'd need a pretty large and powerful light to
    be visible in daylight. Same goes for turn signal lights. Think about how large the turn and brake
    lights are on cars and motorcycles. An arm signal is much more visible during the day and
    universally recognized.

    Brake lights have been done already. Nashbar has one: tinyurl.com3aft7 There are also brake
    pads with brake lights built into them: tinyurl.comuo7m

    Turn signals have been done as well, I had them on a bike as a child. They're quite common on mopeds
    and if I was going to put some onto a bicycle I would just use the same system as a moped or
    scooter. It would be just as important to have turn signals that are visible from the front as well
    as the back. I don't know about where you live, but around here people in cars do not use their turn
    signals, so I doubt signals on a bicycle would do anything ... people don't even use lights on their
    bikes at night.

    I've seen signals on mopeds, but if your bikeframe is like mine, it has panniers, an underseat bag
    (tools), and, at times, a front bag. All of this would make it difficult to find space on the frame
    for locating such devices so that they would be visible. Also, I think they'd need to be fairly high
    up, perhaps integrated into the seat (or vertically from it, in some manner) to be visible enough
    for use. It might also be possible to design something into clothing that might work, though this
    might take some kinky tinkering to find materials that would work. I've taken to mounting lights on
    the headset, seat post (when I'm not using the seat bag), back of the pannier rack, and even my
    helmet, so I think it is possible to do something pretty creative with lights. The lights aren't the
    issue, making a mounting system and human interface that works universally is.

    Good luck,

    Rick

    So, you mean, turn signals and brake lights.

    Drivers of motor vehicles have a variety of responses to bicycles, to wit:
    A. fear, ie, the bicyclist is likely to do something weird or dumb, and I, motorist, might
    accidentally run him/her over and have to do a lot of paperwork, have my insurance payment go up,
    and feel guilty. B. Anger, ie, this moron bicyclist is in front of me, impeding my ability to
    drive as fast and as recklessly as I otherwise might, and therefore, it is my right, nay, my
    duty, to intimidate the bicyclist into never riding again, or at least, never riding in front of
    me. C. Obliviousness, ie, I am consumed with what my boss said to me before I left work, or the
    size of my coworker's [censored], or the fight I had with my teenager, or the cool song playing on the
    radio right now, that the bicyclist riding along in front of me does not impinge on my
    consciousness.

    So, you have fancy turn signals and a brake light. The best part of these might be that people in
    the C. category might notice you. Downside, they then might catapult into the B. category. Most
    likely, they would go into the A. category.

    So, now the people who are noticing your signals are fearful because of your potential
    unpredictability. What you need to do is reassure them that you are going to behave in a
    comprehensible, predictable manner, such that their risk of hurting you is relatively low. The
    question is, do these proposed signals produce that desired effect?

    Adrian, I dk what country you are writing from, but here, in Washington State (USA), everybody who
    has a Washington State Driver's License, at one point, had to learn the basic hand turn signals. One
    of the things I think I do to be helpful to the rest of traffic in general, when I'm on my bike, I
    signal my turns with my hands. When it's dark, I have reflective material on my gloves and a
    reflective armband on my forearm to enhance the motor vehicle operator's view of those signals. I
    hope that everyone remembers that hand signal portion from their license exam, even if it was fifty
    years ago, such that when people actually do notice me, they notice the signal and feel I am being
    predictable.

    If I had some sort of amber light blinking, they'd go, oh, amber light, and then they'd think, what
    the hell does that mean? And they wouldn't know. They'd still be fearful. I would not have
    communicated effectively. And I'd probably still use the hand signals, anyway.

    Or, as is common with drivers around my neck of the woods, the flashing amber light is a signal
    which communicates to other drivers that you DARE to invade the space in front of them ... and the
    response to that is to speed up to keep the idiot (only a wimpy looser would use their turn signals)
    from slowing you down. I can only see this being worse with bikes ... who would want to let one of
    them in front?

    Communication is key, however you have to adjust it to the lowest common denominator ... the ape who
    spent 3 years in the 8th grade, is 43 years old, on probation, unemployed, living with Mom, has 4
    beers and a joint in him on his way to buying some crack and has a taco bell wrapper covering a
    broken brake light*. These people can't figure out the most basic driving skills ... indeed, they
    can barely function as human beings ... the most you can hope for is that they see you, and
    something in the nether regions of their primitive brains kicks in as says "ugh, do not hit, hit not
    good, cop show up, must keep stash". Have you ever tried to hold a conversation with one of these
    people, say, about what side of the knife to use when slicing bread (alls they know is bread is
    white, and comes pre-sliced)? It's freaking scary knowing these people drive ... it takes them a
    whole minute to figure out the door they're pushing says "pull".

    Hopefully, the OP lives in a more sedate corner of the world. I like the idea of a simple light bar
    that integrates brake and turn signal. Does anyone remember the cool turn signals some old muscle
    cars had? I think the 1970 ish Mercury Cougar had them as an option ... they were "chase" lights.
    When you hit the brakes, and put your turn signal on, one side would stay solid, and the other side,
    instead of simply flashing, would "chase" from the center to the outside. Take a look at this
    picture and you may get an idea how they would work: tinyurl.com2aqbf You could have a thin
    row of LEDs which would mount on a bar horizontally under the seat in the back, and perhaps
    something similar across the front handlebars (depending on type of course). For the back, at least,
    it would be cool. It would be simple since running lights, brake and turn signal would be handles by
    one unit, and it functions in a way most people are intuitively familiar with.

    I'll agree that hand signals should be, but there have been several times in Scranton where I've
    seen people stop opposite me in an intersection, making the left turn, as I'm making a left turn.
    They motion me onward, or sometimes wave their hands to get me to stop. And at the end of it all,
    they give me a "Ohh, you're going THAT way?!"

  10. Thanks to the people who wrote a responce its all been very usefull,
    there are a few things i would like to add:

    Alot of you have pointed out that really the standard way of indicating on a bicycle (using arm
    signals) is more than adequte becasue it is universal whereever you go and the majority of other
    road users are going to know what your telling them and this is a fair point. However , have u ever
    tried signalling when you are going up a steep hill.... if u havent it is next to impossible

    imagine this: you are going up a steep hill youve got cars behind you and there isnt really room to
    overtake... your getting slower becasue its hard work getting up the hill and then you want to make
    a right turn... you dont really want to be sticking your arm out when your allready unbalanced.

    Another thing is that you haver to consider is the road surface , i live in a smallish farming town
    in devon (UK) and well have alot of crappy roads, and we have huge bloudy tractors dropping lumps of
    mud on the road ... not a problem in a car maybe but when your on a racing bike with 1" thick
    wheels. There are more examples but basically what im saying is sometimes its just not safe to take
    a hand off handle bars when your cycling.

    And by the way A-levels are what we in the UK do in year 13 in school

    Anyway please feel free to argue with the points i made

    1. Why? I've never felt the need for any such, and several which have been developed over ther
    decades have simply failed to sell.

    2. Get hold of a copy of December's Velovision which has an extended review of a product of
    this type.

    Go ahead with your A-level design project. maybe you can come up with something better. In any case,
    you'll learn a little more about the design process, which is the goal for you.

    Here, the freshman engineering students all design bike racks for pickup beds. None of them is any
    better than what you can already buy, but someday some student will come up with a better design. Of
    course, I can't imagine wanting to put a bike in a pickup truck bed instead of riding it. ;-)

    A guess: a design for a bike which has actual wheels so can be ridden to the bike track? ;-)
