It always stays on on mine while the battery is working properly.

I'm advised that it should change to red when the battery's low but I've never seen it yet.

The light should be on, as you are right, the draw from a tiny LED like that is absoloutely insignificant. It is certainly MORE useful that you can see the switch in the dark!

Yes, I believe so. The draw from the battery is very low and over a week the battery had not discharged significantly when I left mine connected for over a week, but I tend to disconnect the battery from the light unit if I'm not going to be using the bike for more than two or three days.

Yes mate, it should stay on. As for power useage, it's so minimal I should think that it'd run for years with it on.
Great light though isn't it?!

I wondered if it would come in again. It did! and was delivered within 36 hours without trying to queue jump or anything!

i ordered myn start of january and got it yesterday :D the best headlight around!!

i ordered it before xmas speculatively, not expecting to receive it until jan/feb. it turned up before xmas. excellent value btw.

It comes with a separate helmet mount.

No. Quality, solid helmet fitting though. Light enough that I have cross countried with it on the helmet, Lithium pack in jacket top pocket.

There is only a fitting supplied to mount on handlebars

From what I've read from other similar products it's better to give it a charge straight out of the box, even if it says full give it an hour or so - there's clever electronics to stop it over charging - just to make sure it is fully charged. But realistically it doesn;t matter too much, modern hitech batteries like these have loads of failsafes built in to stop you ruining them! Just try and generalyl speaking get them down to half charge at least before re-charging them and you should be fine. (Battery life is dependant on the number of charge cycles it goes through, irregardless of how much charge the charge cyckle puts in - so if you use it for 5 minutes and re-charge it, it is 'one charge' down, just like if you flattened the battery and recharged it...)

I got mine with UK plug. At local electric shop, a converter plug from UK to EU costs only 4,5€. So - still a great buy.
