Vaguely serious point follows, but first the scores:

Serious commute/roadie types with LED-deathray lighting: Lots.
Serious types who've worked out how to dip1 said deathray: Four.

Amorphous medium-vis blobs with glow-worm-in-jar kit: Six or eight.
Glow-worm-pilots who complain they're blinded when I dip1 my own deathray: One.

Tourette's suffering roadies: One2.


I think LEDs have reached the brightness/popularity point where one really needs 'dip' and 'high-beam' modes.

It seems to me that there are two useful options and a useless one.

The useless one is 'Don't keep a LED-deathray because you're blinding other bike-pilots'. Since (Lots - (Four + Me)) other cyclists are unbothered about blinding other people, it's all a bit game-theory. I also like being able to see where I'm going and avoid dog-botherers. And stupid fucking pedestrians in black clothing.

Useful option one is 'Hack your lighting rig such that it's got a remote dip-switch.' I imagine this is theoretically possible with a L&M Vega, since repeated presses of the 'go' button cycle through the available lighting modes. However, this would require wholesale warranty-voiding and likely tying the thing to one bike.

Useful option two is to run a LED-deathray pointed up the road next to a glow-worm pointed at the front tyre (Or pair of deathrays ditto) and just turn off the bright one when approaching another cyclist.

Car drivers can whistle, frankly.



1: In this case 'dip' means 'cover right-hand-side of lens with finger such that there's enough light to still see the edge of the track, somewhat like what I remember Cibie Z-Beam headlights used to do.

2: One can only assume something unfortunate had happened to an expensive bike. He came swearing past me not far out of Bath, and vanished into the murk. Some minutes later, I come upon a high-vis pair bent over a bike not far from Bitton station. 'Fucking cunt!' one of them is going. I pedal on and stop for a half-time energy bar at Bitton. Mr. Sweary is only a few seconds behind me, since he comes steaming through the car-park as I'm pulling a glove off, yelling 'FUCKING CUNT!' at the top of his lungs.

My bike has a Cat-Eye dual light rig (plus a third Nightstick one); there's a remote switch. Being a car driver, I understand high/low beams, I use my wide beam normally, and switch the spot on for appropriate areas. Downside is compared to LEDs these are power hungry, heavy and dim. They're also a fraction of the price.

Still, it's not exactly rocket science, is it?

Oi! As a frequent late-night Pedestrian In Black Clothing, I resemble that remark!

(I almost always have an escape plan involving diving into a ditch, though. Also, usually when I get hit by a car, the car comes off worse, so cyclists should beware.)

The instruction pack for Dinottes specifically recommends dipping. But they're easy to adjust on the fly as they're only held on with a glorified rubber band.


ION, My First Carradice arrived this week. The beard's on its way and the CAMRA membership's in the post.

I've been looking for the LJ entry where I nearly walloped into some black-clad twit a couple of years ago, but I can't find it.

I fear if I had hit that one, physics would have been on my side.

Ah. The Vega's firmly bolted and is a MTB thing.

I trust you bought the Nathan Barley model.

Would a mechanical hack work, with two positions for your deathray ? Then you just click it downwards a notch to dip it.

In marginally-related news, I've replaced most of the 12v halogens in our kitchen with LEDs like this: http://www.ultraleds.co.uk/u16hb15cw-mr16-acdc-cool-white-angle-lumen-p-1994.html

Colour temperatures are a bit funny, but I am installing several sorts to average it all out a bit. Bulb cost payback is about a year.

I'm not quite that bad -- if there's no pavement, I do at least walk on the right. Quite often I have a torch in my hand to illuminate me if I think a car's not seen me, too...

Speaking of cycling. This http://www.cicleclassic.co.uk/ is happening in April and goes past our front door. Come up for a visit?
