'hiccups' can either reset the device or damage it or destroy it
if it properly resets then it'll work as before,well it should...
if it damages it, it could 'alter' how it hows,usually not good..
if it destroys it, it's more Ewaste to deal with ,as in... 'no user serviceable parts inside'
a lot of PIR motion outdoor lights have the ability to stay on , if you flip the power switch, off-on ,at a certain rate of speed. It's common to have 'hiccups' (wires blowing in the wind,bzz,) that just happen to mimic that.... then the dang light is ON until you kill power to it.
