Large yellow & red lights on Red Hill Ave, going South towards Irvine Blvd. The lights simultaneous disappeared as I approached.

I was driving on Red Hill Ave, going South. The road was very dark, and I was the only car in this stretch of road. It was between La Collina and Irvine Blvd at 10pm.  No street lights at all. In the distance I saw large yellow and red lights across the 4 lane highway. There were probably 10 lights on the pavement. It looked like a police barricade or road work. When I came closer, all the lights disappeared simultaneously. It was spooky. I mean they disappeared before my eyes. There was no one else on the road. I looked to see if the lights were there, but turned off, but nothing was there, only the street. I looked up at the buildings and there were no lights. I was freaked out because it was so odd. I have never seen anything disappear like that. They basically vanished into thin air.
