trianglar in shape, black with 3 different coloured lights at the "points" of the triangle

appeared out of the darkness-lights seemed to be flying close together at a fast speed it flew across the road and out towards pershore as the crow flies. it then speeded up and dissappeared.all the time the lights seemed to glow strong and then become dim but still visiable

when i saw it first there was something odd about it-i opened my car window and slowed down-no other traffic on road at that time-which was a bit odd in itself. with the car window open i could not hear any noise being made which if it was a plane of some kind there should have been, with it flying that low. as it flew over the road it seemed to "bank" so i could see the shape more clearly and the inside of the triangle was a matt black colour which seemed to "shimmer"-thats the only way i can put it. the other "effect" for want of a better word was that a trip home that always takes 45 minutes to an hour was concluded in exactly 30 minutes. as a professional person i felt i had to report this but did not want to go to a police station as they would think i was on something.
