I was scared off the Chinese lights after reading about them going pop.
I picked up some Tumble and Fall 2000 moomin lights for about £70 new on eBay.
Not perfect but bodged a GoPro Mount so I could helmet mount them and stash the battery in my Camelbak
For £70 I’m happy with them and good enough for lighting the trail around South Wales up to hit at pace and good enough battery life.
These, better price too:
