I have already posted this on a cycling forum, but figured there might be some knowledge to draw from here -
Aside from being a dedicated climber, I am also a dedicated cyclist. I own several handlebar bar mounted lights for cycling and also own a nice headlamp for climbing. However, without a bunch of tinkering, there is no cross-compatibility between the application of these devices.
I am looking for a light that I can wear on my bike helmet while mountain biking for close-up visibility (again, I already have several bar mounted lights), but that I can also throw into my climbing pack as a backup headlamp in the event my main headlamp were to fail. I don't want to but two lamps as I feel that it's rather frivilous to have two devices for very similar applications.
However, the closest thing I’ve found to a headlamp that does double-duty as a bike helmet lamp is the Petzl Tikka for which they make this “ADAPT” kit - http://www.petzl.com/us/outdoor/headlamps/tikka-zipka-tactikka-accessories-0/adapt-tikka-family. HOWEVER, having a big doofy looking piece of plastic semi-permanently stuck to your helmet means that is blocks ventilation holes, cannot be easily removed and applied to one of your other helmets, entrusts the security of whatever adhesive they’ve chosen to strongly adhere to the ridges & irregularities of your helmet, and did I say it looked doofy?
Anyhow, does anyone have any suggestions? Please!
