You can change that. Not much, but at least it’s different.
This stupid idea left me stuck with a wad of $15 TrustFire F20s which I will NEVER use. There is NOTHING more embarrassing for a flashaholic than to GIVE someone a nice, useful $20 (after I upgraded them with XM-Ls) flashlight, using safe batteries they can easily find; only to have them hand it back with some comment involving the words “piece of s**t”… The one guy who took one, within a week or two, threw it into the woods behind his house & cussed at me anyway.
Sorry, I’m becoming addicted to telling how much I despise these stupid blinky modes…
