1 OR 2 SMALL SPHERES

I was dropping off cardboard at a recycling bin & I noticed a set of glowing reddish to white flashing lights. The sky was clear over Lake Erie & the lights caught my attention. I have lived in the area over 5 years and have used this location for over 2 years. I never saw these lights before. I then drove over to the park and watched these lights for about 3 minutes before the lights disappeared. I stayed there for about 2 minutes waiting for them to reappear, they did not. I went home, less than a 1/2 mile away. Approximately 30 minutes later I heard the unmistakable sound of a USCG Helicopter.
