that bolt will embed itself into the wearer's skull if it hits the ground directly

Yes I was just going to say the same thing. I see folks with all kinds of stuff hooked to their helments and I just wonder if they gave it any thought as to what would happen in a crash.

I use sporks as well but I find the velcro they come with work fine to attach to a regular highly vented road bike helmet. I disagree with the author of the hack's assertion that low lights don't do anything. I mount a light on my left wheel stay which about the height of my rear hub. It does wonders for helping produce more distance. Also any lights that can shine off the ground provide a nice ground level glow that really stands out.

I am a big believer in lights low, medium and high.

Lights low, medium, high and flashy, don't forget. First thought I had was also the bolt into skull thing. I found 3M dual lock for attaching stuff to other stuff, including flashy lights to helmets. Better than bolts.

+1 on Bolt-Through-Head. In Maryland, anything like a spike on your helmet (motorcyclists, etc.) is illegal because it would just drive through your skull. Looks really nice, though. I wonder if one could achieve the same effect with zip-ties?

Good idea in theory but sand or cut off that bolt. or even easier just use a shorter bolt and your good to go.

Hi this is Simon, the author of the Helmet Lights Hack. I really appreciate all your feedback and safety concern.

In my defense the bolt was a placeholder while I still put it through the miles on my daily commute, testing how well it withstood typical riding conditions (vibration, wind, all the other stuff). A month has gone by and it’s worked so well that I sort of forgot about it. Whoops.

Anyways, it would be naive of me to ignore the wisdom or crowds, so I cut off the excess bolt threads and filed it down. In the future I still would like to replace it with another type of fastener, something with a little better finish quality than a nut and bolt. A rivet or screw post are the two that come to mind as of now. The updated project can be seen here:

Thanks again everyone for your advice and a very big thanks to Matt for featuring my project. Keep up the great work all and hack away.

Regards,

Simon

Thanks for the Idea

i really liked your blog. you have given very interesting information, a nice post. Thanks for sharing it with us.

Doc Watson

Good safety idea, but surely any penetration of the surface of the helmet by any form of bolt will affect it's overall structure, and reduce it's protection in the event of an accident?
