Three Lights in the sky facing north in the east bay around 9:30pm tonight.

After turning to drive and face north, my buddy, and I saw three lights in the sky in the form of a triangle. They are brighter than the planes that we typically see in the area and much lower. After passing by a tree, the top most light disappears. We turned into a neighborhood so that way I can turn the car around so we can face it and when we did, the lights were gone.
