Indus the protrusions on both sides of the dorsal "spine" of the plane are the Conformal Fuel Tanks (CFTs). These store extra fuel which dramatically increases the range of the F-16 while external hard points can be left devoid of fuel tanks and can be used for mounting armament.
I think with the CFTs the F-16 has the same range as an F-15. I think that is why the Israelis ordered CFT laden F-16s with their own modifications rather than expensive F-15s.
