Two objects appeared to my South West very bright. When the lights dimmed, I saw a triangular shaped objects with color lights.The incident occured on November 26th, 2002 at 9:58 pm. I lived at the time in a beach Condo in Oceanside, California. I was alerted by my security light going on down below my beach condo which is on the beach. I went out onto my deck and could not see any person or thing that triggered the security light. It was a clear night full of stars. I was attracted to a brilliant bright light about 35 degrees to the South West out approximately 2,000 yard out over the beach. All I could see at the moment was the bright light. At first I thought it was a star but then realized it was too large and too close. It hovered for a few minutes then started to dim. As it dimmed I could see all kinds of colored light eminating out from the center. As it dimmed I could see a diamond shape object that immediately took off directly to the West over the ocean. A few seconds it returned and then I saw two objects the same size and brillience. I grabbed my digital camera and started to take pictues. I then grabbed my 35mm Cannon and took the remaining pictues on the roll. The second object seemed to dissapear and the first object staged stationary for the remaining of the 35 minute period. The last object then dimmed, I saw the color triangle and it just took off at an angle and dissapeared to the West. The size of the triangle object appeared to be the size of a full moon from my vantage point.The next morning I talked to a contractor friend building a home next to mine. He told me he was out flying in his Cessna 174 around the same time the previous night and said the object headed directly for him and caused him to dive down to the ocean level and return to the Oceanside Airport.I sent the digital pictures to a company in Irvine to be analyzed. I was amazed to see the color triangle and a what appeared to be a beam of light from the object to the ocean. I developed the 35mm pictures but there was nothing but a bright light image on about six pictures. I sent them off to Irvine and I was told that the same light eminating from the object to the ocean appeared to hit the lense of my 35mm camera. No specific images on the 35mm pictures could be ascertained.Immediately after the incident I had a significant headache for about three days. No other reactions have been noticed. The object did reappear about two weeks later for an a few moments late one night.I and my wife had wittnessed object on two occasions in the previous month. One while driving down High-way 1 from Monterey and the other driving back from Reno, Nevada near the Sierra Nevada Mountains.
