Hi -- I haven't been able to find the answer to this question in my owner's manual or on Lights&Motion's website: do any of you who have the Arc Li-on headlight know if it's OK to use it in the rain without damaging the lamp and/or battery? Or do any of you have a high quality light that you can use in the rain? I mean a light that lets you see, not just be seen. Portions of the trail I ride are pitch dark before dawn. Thanks!
