I use velcro but my light is very lightweight.

The best bet for heavier lights is probably the cateye helmet mount.
About 15$ at the LBS last time I saw one.

For my halogen I used one of those cateye mounts, hack sawed the pivoting mount off and zip tied another Velcro strap on. Works mint :thumbsup:

Sorted! Managed to fashion something with the two smaller velco straps that comes with the system, and detached the handlebar mount which gave a cross bar. Placed some rubber under the cross bar and then fasten in opposite directions means it's very secure and removable.

Thanks for all the help.

6 x Cree R2 LEDs. Plenty of light. 1380 lumens for under $150
Lights up the road up to 50m plus.

Any chance of a photo of what that looks like on the trail? Looks pretty impressive on the helmet!

That's the stuff you want to miss. Hard to get it out of the tyres.

Just some tri-optics from dealextreme. They work out at about 10 degree spread. I am going to make up a 3rd light for handle bar mount with about 50 degree spread.

Thats what I keep thinking :huh:

Granted, I use a set of Ayups, which a pretty good, but buy the 'new' standards they are not so much. Cant see the point in having daylight in front of you when you are on a night ride.

50deg would be to wide, 15-20deg (max).
Thats a nasty hot spot are you able to dim them any?

Yes, dimable from 1000mA down to 350mA. Not a huge amount of light difference but run time would be greatly increased.
The wide angle light for the bar would only be to give some immediate light for close obsticles so as to avoid looking down. Just trialing setups at the mo. Also it would be useful to cast a bit of light when I get my camera mounted.

Theres a point where you have enough light to ride comfortably and after that its just waking up the bunnies and possums.
