Blue and red light makes radical direction changes, comes to complete stop, and flashes white strobe.

Seconds after I noticed a blue light with a with a smaller red light attached to its upper left side which was traveling N to S, the object changed direction abruptly to W to E.  The object "turned on a dime," which immediately made me rule out that it was an airplane or helicopter.  I followed it from left to right behind some trees, until it emerged in an opening.  At this time the object came to a complete stop and began to flash a white strobe slowly at first and then faster.  I thought the reason the strobe increased in speed is because the object new I'd spotted it and that's when I retreated in to my house.  
There are only two explanations to what this could have been, a drone or something, etc.. 
Also, I couldn't really tell how far away it was because the lights were the size of airplane lights.
