I gotta revive this old thread.
The cracks on my yellow 24/7 grew to the point where the battery cap is completely lose and won't stay inside the battery compartment. The light's been sitting in my car for the longest time, so I'm not sure how the cracks could've developed, or why they got worse.
From what I'm re-reading here, it sounds like these cracks sort of develop on their own? Other than a relatively short stint as bike flasher, it's been sitting in my car's emergency box for the longest time.
From the reply e-mail I just got from Inova, it seems like it
might get replaced, but their technicians have to see the light first (pun intended). Oh, and there's a $5 fee for S&H. I'll keep you guys posted.
I'll try to post some pics before shipping it out.
