I've only played with the mode when I found out it was there but hidden. I have a cheap chinese DIY power bank that does SOS if you hold the power button down for about 5 seconds. I don't find strobe or SOS useful so hiding that mode to me is a non issue as I don't care to skip past the mode to get back to another mode again.As far as I know all my lights have a strobe mode but to date I've NEVER used one in 15+ years
I have a Fenix LD22 that does this. It has 2 strobe patterns that it automatically shifts between when in strobe mode. It’s one of several reasons I will keep this light until it gives up the ghost.As posted above, do any LED flashlights have a strobe mode that switches patterns automatically?
