1 out of 3 exterior lights not working

I have 3 ext lights and one will not work. I'm changing the fixture to an LED unit. The light works and a test socket with pigtails also work until attached to the light housing. My tester warbles when there is power and does not when the switch is in Off. The main switch is a dusk to dawn. There is another switch inside the garage. The other two lights work/respond to either switch. I'm stumped. Thanks!

Welcome to the forums.

My tester warbles when there is power and does not when the switch is in Off.
What does your tester say about neutral ?
You have hot..... do you have the neutral ?

There are two wires to a circuit..... black/hot and white/neutral.
You need a meter to see if the circuit is completely working.

Was the previous light working at that location ?

Means nothing if it is a non contact tester. They are to pron to false positives that just confuse you. You need to test with a multimeter, preferably analog (or a neon test light or a solenoid voltage tester).
The light works and a test socket with pigtails also work until attached to the light housing.
Do you mean junction box?
The other two lights work/respond to either switch.
Are they incandescent?
The main switch is a dusk to dawn.
Not all of those will work with LEDS

I tested with my multi-meter and have 118v from gnd to black. I finally found my install/opr instructions and it only controls incandescent and fluorescent. That was my gut feeling... I'll find a 3-way switch to rule that out. Thank You!
