    If you are that worried about fog I'd suggest a rear fog lamp would be more use, and as a Brucey bonus you'd look less like you got lost on the Long Way Down to the supermarket.

    I also seem to recall bright lights make it harder to judge distance/speed too.

    Yeah - go for it. I think it gives the bike more 'presence' and traffic is more likely to see you. It certainly seems to work with mine!

    As I understand the regs., the rules apply when they are used alone as fog lights, not when used in conjunction with dipped beam, in which case they have to be permanently dipped (so as not to dazzle oncoming traffic) and are classed as 'Driving lamps'. If they are set in a non-dipped direction, they must extinguish with main beam. IIRC, the actual wording is buried deep within the C & U regs. The position is also critical for them to be classified as 'fog lights' - they have to be below the bumper height of a car, essentially, which means that, when mounted on a GS, they will be regarded as 'driving lights'

    As a matter of interest, my current car (2001 Xantia) is the first to have fog lights which are actually useful in very foggy conditions.

    How fantastic! Whay doesn't EVERYONE do that? There will be no problems for motorcyclists at all. It's such a good idea I'd make it a law.

    Perhaps not.

    The problem is - you can't "dip" driving lights, because by design they do not have a dip beam pattern - they are designed to through a narrow beam of light up the road as far as possible. So you end up riding round with these things on dazzling people.

    Foxy:

    Shaw 1979

    Compared the accuracy with which subjects estimated the speed of a motorcycle with headlamp on, and off.

    Subjects over-estimated the speed for lower speed of approach
    Subjects under-estimated the speed for higher speed of approach

    The reversal from over- to under- took place between 50-55mph with the headlamp off, and between 35-40mph with the headlamp on.


    littleredrooster:
    The 'at risk' zone at junctions is about 3 - 4 seconds (PM me an email address if you want more on this).
    Are you seriously saying that a driver who looks won't see you 3 seconds away?

    [Remember most SMIDSYs happen in urban areas]

    Isn't this just another version of the hi-vis theories that it might help another road user see you sooner so he might do something different to protect you from harm?

    But how much greater is the benefit of being seen 3 miles away than 2, 1 or even 400 yards?

    It's useful if you drop your house keys in the dark.

    I have one on my V50.

    Er! something you are not telling us?

    Seriously, whilst I will use it with the best of em', I think that the big problem with all high-viz aids is that they foster a sense of false invunerability. You and your skills and your roadcraft (Small r - before you lot start!) are the biggest aid to accident avoidance.

    Ah, but if you're as slow as me they've got sick of waiting and bought their own. Then the queue has gone by the time I arrive.
