Yee Colour Light Bulb won’t reset

The Yee light bulb was not connecting, and so I tried to reset (five times on/off at 2s intervals) but it won’t reset. So can’t connect and can’t reset. It’s also flickering very very fast, almost you don’t notice but defiantly there. I’ve also checked to see if the Yee wifi network Becomes available even though it doesn’t go in to colour flashing mode but it’s not there.

And advice on how to reset would be helpful.
