BIG, black traingle shape with red lights at each point, quietly & slowly flew above/by me in LA area '92/'93

It was either early 1992 or early 1993 in Los Angeles area (Chatsworth), CA.
around 8:00PM PST I was standing outside of my friends house, in the back yard, smoking a cigarette.
As I was looking up to the sky I noticed a BIG, black object in the shape on a "V" or a triangle.
It was big enough to block out most of the sky above me(I guess it was a low in the sky, but I can't say exactly how high).
It had red lights at each "point" It was quiet, almost like a soft swoosh sound and it was going slow.
Slower than a regular airplane.
It almost seemed to hover, but it slowly made its way across the sky and past the trees.
It just kept moving until I could no longer see it.
 I havent repoted it until now, because I've been seeing all these reports of UFO's that are ALL similar to the one I saw in the LA area about 15 years ago.
But I've never heard of someone seeing something in LA; just in Phoenix, Illinois and Mexico.
 I'm just writing down what I KNOW I saw.
 It was a long time ago, but I can still see it clearly in my mind.
 Are there any other reports of a UFO in LA during that time period? Thats what I'd like to know, because I DON'T think I was the only one to see it.
 I am a male, 36 years old as of 2-2-2008.
I noticed the UFO right before we left to a show/gig where my band was playing at the time. (I was about 22 or 23 years old) I own my own business and have no history of seeing UFO's.
I also have a wife and child.
I am NOT crazy.
Witness indicates that the date of the event is approximate.  PD
