what is this?

Location: the outskirts of north london. 

me and my husband were walking home from work. i saw a green light across the road that looked like a bike traveling down the empty street. we crossed the road and i saw it stop in the middle of the road, then shoot up into the sky. I pointed it out to my husband and we both observed it hovering for a while, then blinking, then moving at high speed away from us. it stopped, vanished, and then we saw it the opposite way of where i was recording. it hovered there and blinked for a while, turned bright yellow and then completely vanished. we couldn't find it again.

the video taken isn't the best quality because to be honest i was in shock. I've never seen anything like this. i tried to search about it but nothing i found was a similar description to what we saw. 

my husband doesn't believe in ghosts or aliens and things so he is also intrigued as to what it might be.
