Look very similair to what I saw whilst on the A12 one night, I called the police in the end because people were parking in lane one to get out for a better look!
Turned out to be tealights with some sort of 'parachute' above them and were simply carried up from the heat of the tealight. If I recall it was to celebrate Diwali (sp?).
I parked in a layby and waited for the police so I could explain why I had called in case the lights drifted off before the police arrived. The copper thanked me for calling and we agreed that should it be an alien invasion we were both going to head for the pub up the road for a few cold ones.
Brave eh?
