Lightweight Fighter program: The Lightweight Fighter (LWF) program was a United States Air Force technology evaluation program initiated in the 1960s by a group of officers and defense analysts known as the "Fighter Mafia".  It was spurred by then-Major John Boyd's Energy-Maneuverability (E-M) theory, which indicated that excessive weight would have severely debilitating consequences on the maneuverability of an aircraft.  Boyd's design called for a light-weight fighter with a high thrust-to-weight ratio, a gross weight of less than 20,000 pounds (9,100 kg; half that of its counterpart, the F-15 Eagle), and high maneuverability.  It resulted in the development of the General Dynamics YF-16 and Northrop YF-17.  Late in the program, in 1974, with the promise of European sales, the Air Force changed the program name to Air Combat Fighter (ACF), and committed to purchasing 650 models of the YF-16, adopted as the F-16 Fighting Falcon.  The U.S. Navy adopted a modified version of the YF-17 as the F/A-18 Hornet.

VFAX: VFAX for Naval Fighter Attack Experimental was actually two specifications for two US Naval fighter projects.  The first was for a low cost lightweight complement for the F-111B which could replace the F-4 Phantom II for air superiority, escort, and ground attack missions in the early 1960s.  This role was dropped in favor of the VFX aircraft, which emerged as the F-14 Tomcat.  The second VFAX evolved when the VFX proved too costly to replace all existing fighters and attack aircraft, and the Navy was invited to take part in the USAFs Lightweight Fighter Program (LWF).  The Navy chose the "loser" of the LWF contest for its VFAX role, which was redesigned to become the F/A-18 Hornet.

Northrop YF-17: The Northrop YF-17 (nicknamed "Cobra") was a prototype lightweight fighter aircraft designed for the United States Air Force's Lightweight Fighter (LWF) technology evaluation program.  The LWF was initiated because many in the fighter community believed that aircraft like the F-15 Eagle were too large and expensive for many combat roles.  The YF-17 was the culmination of a long line of Northrop designs, beginning with the N-102 Fang in 1956, continuing through the F-5 family.

Light fighter: Light fighters are fighter aircraft towards the low end of the practical range of weight, cost, and complexity over which fighters are fielded.  The term lightweight fighter is more commonly used in the modern literature, and by example tends to imply somewhat more capable aircraft than light fighters at the very low end of the practical weight range, but the terms overlap and are sometimes used interchangeably.  Whatever term is used, the concept is to be on the generally lower half of the practical range, but still with carefully selected competitive features, in order to project highly effective force per unit of budget via an efficient design.  As well designed lightweight fighters have proven able to match or beat heavier aircraft plane for plane for many missions, and to significantly excel them in budgetary efficiency, light/lightweight fighters have proven to be a strategically valuable concept.  Attempting to scale this efficiency to still lower cost, some manufacturers have in recent years adopted the term “light fighter” to also refer to light primarily air-to-ground attack aircraft, some of which are modified trainer designs.
