Thread: led lenser mh5 help

I've got one of these. Good headlamps. My one has never had that problem - the travel lock is toggled off/on by holding the on switch for about 10s, and the front red light flashes three times if the main switch is pressed when it is in lockout. You might have better luck dealing with ledlenser directly for advice. I dealt with them on this email address:
Ledlenser Administration <admin@ledlenser.co.nz>
when I needed to get a warranty repair to the battery clip.

I found them really easy to deal with - hope you get it sorted.
