I was coming from Nov Rd headed north n turned into 4tg street and not rice a triangle shape something with vlpulsating n beeping light

I was riding my bike on nova turning into 4th Street which come in contact with Dal Maso where I live. As I was coming from nova into 4th headed west I saw a Triangular 3 pulsating lights that we stationary with what seem to be something in between but I couldn't see it. It was perfect length to make it a perfect triangle. Then one light turned of making it only two pulsating lights. But, then something weird and unexplainable happened. One of the lights on the right, another beam of light came out and started dancing or doing weird movements next to second light of triangle on the right. It looked like it was a little comet flying perfect into it but then doing weird manuvers. The 3 lights then came all back on. As I was trying to chase it DISAPPEARED. It was not fireworks. No fucking way. I felt for a few hours after it happened dazed and lost. Ir was not a negative experience.
