    Blinded very badly if temporarily on towpath last night. One of my regular towpath people had the sense to cover his light as I was hanging over the parapet on the aqueduct t escape his searchlight beam. There is almost no dipping of these lamps anymore. Plus they are far brighter than previously.

    Interestingly the bracket on my Aldi lezyne copy USB chargeable lights with replaceable rubber O ring has an asymmetrical bracket which tilts the beam down (or up if you put it on the wrong way or want to tilt it up eg back light).

    EBC have big and mildly informative article on lights rather than just advert just now. Clipping them on to bag or helmet not same as attaching to bike which is the legal requirement it says. I have commented that they should stock brackets that force the light to tilt Down.

    The aircraft landing lights were fun but very many unilluminated dog walkers, dogs and runners. The boats all had their lamps on.

    MoT for bikes the answer? Or acceptance of the buccaneering spirit behind the pesky blinders?

    The canal needs streetlights between Lochrin and the bypass

    In twilight this week I've seen some very bright ones, although they're not problematic until it gets properly dark. Soon we'll have to wheel out the comments/advice to the perpetrators, although they seem to either not care or not know how to fix the problem.

    I confess to having an overly bright Cree, but it easily swivels (rubber-band mount) and on the canal I keep it pointed at the ground by my front wheel. No complaints so far.

    The two functions of a front light are for a cyclist to see, and to be seen. Perhaps some people believe that by dipping their front light in the slightest way, they are somehow compromising the latter?

    The problem with most front lights is they do not cast a directable beam, but instead splatter photons everywhere. Even when you point a non-beam-forming light down, it will still be too bright to on-comers.

    In Germany, they have a standard for front lights that they must be beam-forming (much like the dipped headlights on a car)

    Maybe we should adopt this standard in the UK.

    Even those can be a little uncomfortable on a shared use path if the oncoming cycle is coming down a hill and one is on the left side of the path they're still very bright.

    @nedd1e_h I'm not sure that I agree. From experience, I find that it is incorrectly fitted/positioned lights that cause most of the problem.

    When I look at the worst offenders, either as I sit behind them or as they pass, they are mostly using directional (bullet) front lights positioned horizontally.

    I find that the non-directional lights tend to be less intense and have the advantage of making the cyclist more visible from a greater range of angles.

    I suspect that standards for bicycle lights won't make it onto any UK government's agenda any time soon.

    If I still did the canal I'd get one of these. My Exposure Joystick has a well-focused conical beam but the mount is engineered alloy and moves not a jot.

    A lower mounting point does seem to make sense. Some modern bike lights have GoPro-type brackets, which should mean that something better could be cobbled together for them from the wide range of compatible aftermarket fitting hardware that is available.

    ISTR the my first bike back when I was kid had the lamp bracket (to which you fitted an Ever Ready front lamp powered by a number 800 battery) down by the fork crown. That was a Raleigh Twenty, so it would have been quite low. I have a vague, though very possibly faulty, recollection that my first 'proper' bike - 27" wheels and 10-speed gears with downtube mounted friction shifters! - had the bracket mounted on the offside leg of the fork itself.

    EDIT: Amazon UK lists a similar-looking piece of kit to the Problem Solvers one, for £3.99:

    https://www.amazon.co.uk/MagiDeal-Bicycle-Release-Cycling-Extender/dp/B07635RNVN

    I can't vouch for its robustness or quality but at that price it might be worth a punt...

    There are a number of other similar-looking products on eBay, including one that looks identical to the Problem Solvers one:

    A B&M Lumotec has quite a narrow focussed area, but the spill outside it is very inoffensive:

    A Philips Saferide has a distinct horizontal cutoff, but can still be painfully bright even above the horizontal cutoff, though Dave would dispute this:

    Neither are foolproof, as the fittings on both allow the pitch to be changed easily. They both look like they're meant to go on the fork crown but there's nothing to stop them working loose and rolling sideways into a wheel, so both are attached to the bars with a range of extra bolts, nuts and fittings for other devices so that they only move when you really want them to.

    I had a look at some rechargeable lights in a shop earlier this year but none had any kind of eye-saving beam-shaping, so I'll stick with my current secondary flashers and leave them pointing very down.

    @wingpig, nice drawings

    @snowy, when we passed on Monday night, how was my light for you? To be honest and a little pernickety Yours could have done with being pointed a bit further down to the ground as it was slightly in my eye. Sorry.

    @wingpig - B&M beam pattern lights road well without dazzling oncomers.
    Going to get the 17 year old SON hub and fit to invisible bike. Using self generated lights maybe old school but the beam patterns to German specs light roads well.

    @gembo I didn't notice your light from which I conclude it was perfectly fine. Noted about mine - I obviously wasn't being careful as it was still mid-twilight.

    I feel a beam-pattern-experiment with some insulating tape coming on.

    @snowy no problemo chief honcho. Original Dave previously suggested a Peter's yard check each other's dips and the other night on WoL path I was definitely not dipping. No way I am without sin.

    Sorry to freeload on here with a really tenuously linked topic...
    But @wingpig you mentioned a Philips Saferide... I've been trying to find a spare bracket for a Saferide 80, you don't happen to know if it's possible to buy them perchance? (Or something else that fits)

    The light itself appears to be discontinued which is a bummer because it's great..

    Spotted - a light adaptation at work parking:

    NB backup light has TAPE. Please let them live...

    That bodge might cause a slight dip in the beam? Which is always good.

    @schemieradge My first Saferide bracket snapped, but B&M make a similar thing which fits. I'll see if it's in the cupboard it's supposed to be in...

    Aha... I noticed on Rose Bikes, under the (unavailable) saferide 80 they were showing a similar looking B&M bracket as a related product..
    Is it this?

    Nothing so fancy. Something like this:
    https://www.sjscycles.co.uk/lighting-spares/busch-muller-light-bracket-for-lumotec-oval-iq-fly-long/
    Also available in a short version. It's a bent bit of wire, so is stronger than the stamped thing (with built-in weak points at the chamfered section) which came with the Saferide.
    I think I have one, unless I gave it away to SRD along with the spare rack it was attached to when it was pretending to be a mudguard bracket. I'll inspect my cupboard and boxes this evening.

    I can see how that would be sturdy, but I can't quite imagine how it would fit... I wonder how many different saferide models there are.?
    This is what the bottom of mine looks like: https://www.dropbox.com/s/rt6makavrdgf7ok/IMG_20171122_113223928.jpg?dl=0

    Same as mine - I think the original Saferide bracket came with a two-part sleeved bolt thing, but a long M5 bolt can be persuaded through, which then clamps the eyebolt ends of the bracket either side of the plastic bit. I probably added several shakeproof washers and possibly attached the bracket to the handlebars with hose clamps but I have the wrong bike with me today to check.
    There's probably a photo of it somewhere on my phone...

    Looks like I'm currently using an angle bracket hoseclamped to the handlebars for the geared bike (Saferide) and a re-purposed clamp from a Minoura SpaceBar bolted to a B&M wire/eyebolt mount for the singlespeed (B&M Lumotec). Both systems mean I can ge the light almost central and in front of the stem clamp, minimising the areas cast into shadow from my handlebar prongs.

    Spare:

    I've not yet had a light-fitting problem which couldn't be resolved by a trip to Wickes or the Bike Station.

    Wow that looks extremely cunning - although I'm embarrassed to admit I don't have the sketchiest idea of how that could be used to fix a light to a bike without a load of duck tape. We're clearly operating on different planes when it comes to engineering ingenuity...

    That's the remains of the fixing to fit a Lumotec to the underside of the front porteur rack on my old sparebike, so that illumination was not compromised by cargo. The wire bit is not currently in use if you want it. This is my current Lumotec fitting, with the bodged Minoura clamp.

    I'll pop out to the shed to get a picture of the Saferide versus angle bracket in a few minutes...

    I could only find really long long bolts, hence the connector but to cover it up.

    Hose clamps/Jubilee clips beat duct tape, as they can't be so easily ripped-off and add a nice air of random ironmongery and don't-bother-nicking-me.
