there was 2 redish orange glowing spheres spinning round themselves heading my way

i had just finished work after doing some over time and was on my way home,the light in the sky was just starting to fade when i noticed 2 bright lights around a couple of miles away in the sky,as i stood there watching the lights,i noticed that they were getting closer at quite a fast rate,i also noticed that they were like redish orange spheres spinning around each other,i watched them for what seemed like around 3-5 minutes,eventualy just before they left my line of sight they speeded up to an amazing speed(unlike an aircraft as there was no noise at all)and disapeared,a couple of days later while i was speaking to a friend,i mentioned what i had seen,and he stated that he had also seen 2 sphere looking bright redish orange lights,spinning around themselves,but he was in another town atleast 5 miles away from where i was when i saw the lights.
Date of incident may be approximate, although witness does not indicate that fact.  PD
