    DIY Helmet Lights- What kind of mounting?

    So, like the rest of you DIY'ers I love my home built lights. In fact, I feel that their light output, frugal energy consumption and low price put commercially available lights to shame. The one thing that I don't like about my home build is the way that I'm attaching my light to my helmet. That's the one thing that is pretty weak compared to my old NiteRider setup that I was using. I'm using a Marwi mount that I got from Jenson, but it just isn't cutting it.

    I've seen other commercially available mounts, but they are pretty expensive. I was hoping that someone could suggest a good alternative. I think this is one subject that has not been discussed much. If it has, a link would be great.

    Not quite DIY on the light part, but the helmet mount definitely is:

    Scratched up Oakley A-frame lens and some velcro straps. Using the lens meant that I didn't have to stick velcro directly to the helmet. The lens is made of polycarbonate plastic, and was pretty stiff. Basically flex-free. You could use any curved plastic, like from an old plastic bowl or whatever.

    I can't see that working out for anybody who's going to see wooded trails. Every time I ride at night I get a couple nice hangers catch my helmet light (Fenix L1T V2.0 mounted via twofish on the helmet).

    I didn't ever have a problem in the woods. We have spruce, pine, poplar and birch, so nothing too dangly.

    This is exactly what I use and I think it is great :-) Is your light very heavy? Show us a pic, then suggestions are easier to think of :-)

    Some use velcro glued to the helmet or strapped on and then the light directly on top.

    Also, for one of my Achesalot lights, I made a mount from 1" square tubing:
    A) on the light I mounted a 15 mm piece with one side cut off and the middle flat part soldered to the light (i.e. two "legs" protruding from the light).
    B) the helmet part is a longer piece of square tubing where three sides are cut off, except in the middle, where two corresponding legs are protruding. This piece is pop-riveted to a piece of plastic that I cut from the back of an old office chair, made wholes in for velcro and then shaped to a curve (helmet fit) with a hot-air-gun. This is a VERY secure fit - but the light only weighs 115n grams including mount.

    OK, found the pictures - they are selfexplanatory

    Pinkrobe, I like your mount. It looks stable, though for where I ride, I would worry about the height too.

    MoMaTo, yours is sort of what I have been looking for and thinking about. The biggest question that I have been wrestling with is how is the tension maintained between the light and the mount? Do you have a problem with the light tilting forward at all? I like the way yours sits on the front of the helmet instead of on top. It looks like I could get a lower profile by moving mine forward. Can you post a picture of the link between the light and the mount?

    Here is the light with the current mount.

    OK, so linking pictures from Picasa does not work. Here is the link that I tried to show. No problems with tilt, solid as a rock. The nuts are self-locking (the blue plastic-thingy in the threads)

    Two threads on this

    Here's one by rockymtnway that uses the Nitepro head mount.

    And another thread that asked the same question. Lumbe1 made one from square tubing.

    That's what I'm looking for. And the joint is just metal on metal? I think I'll borrow that design for my next one. I like the plastic base. The setup looks properly stable and adjustable.

    Thanks.

    there is a washer in between. But I rarely ever adjust, so that is probably not necessary.

    I used the same helmet mount and after a lot of time building an adjustable mount, I tried it and felt the the light sat to high off of the helmet. I'm already 6'3" so I was trying to keep things as low as possible. I took the mount out and sawed the legs off of the plastic and screwed the flat plastic right to the bottom of the light. Just slide the mount forward or back on the helmet to adjust and it works great.

    Good luck
