Hey Melinda==Check to make sure there is a good ground between the engine and body with no paint or dirt. Also remove both battery cables and clean both ends. This should do it. GoodluckJoe
Maybe a loose wire or a bad connection to the headlight itself.
There may also be a security function that has been triggered by the battery being unhooked during the alternator installation. My Jeep does this every time the battery is reinstalled in the circuit or is drained and recharged. I must then reset the security to get it to function properly. Good Luck finding the problem & hope this was helpful, Joe.
On a 1999 GEO Tracker, a bad fuse can cause the headlights and dash lights to blink. A bad voltage regulator or alternator can also cause lights to blink and flicker.

A loose or corroded ground wire can cause your 1995 Jeep headlights to blink on and off. Make sure the ground wire is tight and free of corrosion.
