I tried the Magicshine on my helmet last night, and had a hard time getting the mounting "thingy" supplied by Geoman attached to my Bell Influx helmet. I could get it so that the thingy was tight enough to solidly attach the lighthead to prevent the illuminated area from varying with every bump, or loose enough to allow me to wear the helmet without getting a headache, but not both. I ran the velcro straps across the top of the helmet to the vent hoes on the side and then attached them in the center. This didn't use all the velcro, and attempting to run the velcro through the vent holes closer to the center would leave enough velcro unattached that it looked like it would be uncomfortable. What's a good way to mount the lighthead?
