i saw a strange, steady light about 300 ft about the ground just east of us-127. i first noticed it just passed the clare exit headed southbound. i've travelled this road frequently for several years and i know that it was not part of a communications tower... also, this light did not flash at all so i really don't think it was an airplane or helicopter. it appeared to be relatively large. it appeared to be stationary the entire time i viewed it, though i was driving and the road is curvy so it may have moved slightly and i wouldn't have noticed. it was basically a white, disk-shaped light, possibly slightly blueish. it appeared to glow.
