A close depiction of a UFO I seen about 15-17 years ago when I was a teenager (Used AI to get as close as I could remember)

One night my mom and I was driving back from a family members house, we were about 10 minutes away from home and going over a bridge. It was sunset, from a distance we saw an object in the sky that looked like a blimp with colorful lights going around it, instead when we got closer, we could tell it wasn’t a blimp. It was shaped slightly different, more elongated, no fins or gondola, and the lights were like an LED light strip that wrapped around it with the setting on “rainbow” but more elegant.

The image is the closest I could get AI to generate, aside from the lights coming off of the bottom, this is very close to what I remember we had seen.

She believes it was simply a blimp, but I told her I think it was a UFO. I tried googling blimps in the area but was unable to come up with anything. The image is still ingrained in my mind and everytime I go over that bridge, which is often, I always look in that area I originally saw it hoping to see it again.
