I want to get a helmet mount light but I can't tell how well they will fit on my helmet (Giro Hex) if at all. I've been looking at the eGear K2:

but I can't tell whether it will fit on my helmet nor any other headlamp for that matter. Any tips?

I have done this very thing. You have the best chance of a headlamp fitting a helmet if the battery pack is immediately behind the light. If the battery pack is mounted on the rear of the strap, the power cable running to the lamp may not have enough slack or stretch to be able to be stretched around a helmet. I yanked the power cable right out of the battery pack on a Princeton Tec headlamp trying this. I was able to resolder the cable to the connectors and used the headlamp for another application. I currently have a Black Diamond Spot headlamp (1 1watt Luxeon LED, 3 5mm LEDs, 3 AAA batteries, $ 43 at REI) mounted on my commuting helmet.

I know its a lot more money but i just got a nite ryder evolution smart and its a really nice light, it comes with a helmet and handle bar mount, it fits on my helmet fine and a lot of regular lights didnt want to fit on mine they just slid off, I tryed every light the bike shop had in stock on mine and they all just wanted to slid, I put the evolution on there and its great

Is this going to be your only light, or a supplement to a bar light? It makes a big difference..

Princeton Tec has some nice bike specific lights that are not too bulky, these would be a good choice as a supplemental light to a bar light.. I am a total advocate for a helmet light, it helps with being seen at night and seeing through corners.

Another great option is to use a fenix flashlight, preferably the L1D or P2D as a helmet light, here is a link to a detailed description of how easy this can be done.. I currently use the P2D as my helmet light..

I'm running a Trailtech Eclipse 13W HID and the helmet mount is a velcro deal (which can
be affixed semi-permanently by using an under-mount adhesive strip) and the light clips
on and off fairly easily.

It also can be mounted on the handlebars but I'm really enjoying having light
go where I happen to turn my head so I haven't used that mount yet.

I'll attach a picture a bit later.

The cable has an inline switch with leds that shows power is being supplied and
battery life remaining which attaches to the cable the battery is hooked to which
goes into a backpack or camelbak or could be clipped to the frame.

As an update: I did a little video to see how it compared vs. a 1 watt luxeon.
What surprised me is that the on/off switch which is at my right side at the
waist has an led battery indicator and when the light is running that light is
VERY visible to anyone who sees me from the side. Added bonus visibility!
The video proves it.

Fits nice.

That headlamp can be found from Rayovac (the exact one shown) at Costco in the automotive area for $17.

Take the straps off and buy a couple 18" velcro straps at REI. Run them through the back of the light and battery pack and mount them on your helment.

You can use the straps that come with the light by removing them from the light/battery pack. However, the velcro straps are a lot easier to remove and reinstall the light.

I've mounted the light on my Fox Flux helment. I had no problems with the power cord between the battery pack and light.

ick! time for you to step up to the Rebel 100 @ 200 lumens

The P3D rebel is by the numbers brighter but testing shows that the Q5 Mod will put out 30 more lumens than the rebel.. I am waiting for the next gen of Fenix lights before I replace the P2D as my helmet light.. It works just fine considering that it is secondary light to my HID on the bars..

If your helmet has a visor that makes a big difference. You can wrap the band between it and the helmet and really secure it without having to attach anything. It makes it easier to take off when needed and I have never had a problem with sliding.

I've had a petzl myo xp (similar to OP light) on my helmet for years. Most headlamps are made to fit heads, not helmets, so the strap will be too small. Plus you need a rubber strap to keep it from sliding off.

On the petzl I removed the strap and attached to helmet with plastic tie straps and duct tape. Sounds bad but actually works good. Also doesn't look as bad as you may think. I mounted the 3AA holder in rear to balance weight f to b.

I use the petzl on flash as a "be seen" light. PB super flash on back of helmet.
