Intentional formation of lights

I lived on Point Loma, over looking the Pacific ocean.  This is the location of the U.S. Navy's top secret submarine program as well as a major Naval instillation.  My friend and myself went outside for a smoke and I saw some lights that seemed unusual.  I am what is commonly called an Indigo child so I am very open to these types of experiences.  I felt an urgency to get down to the cliffs to get a closer look.  The ligths appeared to be about 500 yards off-shore but they did not reflect off of the water so they could have been out over the horizon (20 miles).  They made no noise and  moved with incerdible speed OR there were many of them.  What made them unusual was that they created a changing pattern of triangles.  One light would go dimm then disapear and after it did another would appear in a different location creating a perfect upside-down or right side-up triangle.  I am sorry I can not give much more deatil for sure but I can say that growing up wathching every type of military and civilian aircraft take off and land from Mira Mar (Top Gun), Limburg Field, and Coronado Island I am 100% sure that what I saw that night is either a top secret program or not of this world.
