Need help identifying/changing these outdoor lights

LEDs rarely burn out, you sure the daylight sensor (so they only come on at night) isnt the problem?

Why not just remove that old arse fixture and buy something new?

Where would the sensor be?

its an electric eye, there are many designs, you should see it where daylight can reach it, so look for a tiny little smooth round thing the size of a AA battery somewhere, that is the sensor. it could be mounted at one of the lights or on or near the timer control box.


if it was only a fixed timer, then it may not have one, hard to say.

but the way LEDs work, you dont have a thing where all the lights go out at once, more like just one light, but not all of them.

if you are comfortable with live electricity, i would start by testing each light separately, one at a time, from an extension cord for power and see for sure if they are bad, or if its in the timer control system for them.

have you at least confirmed there is power to the lights that arent working? use an electrical test meter on the red and black wire connections

They started dimming before going out. That was the main reason I noticed

well thats a clue, LEDs dont dim unless the voltage supply has issues. your whole problem might be a bad wire or wire connection that is feeding power to them. i honestly dont think there is anything wrong with those lights

just buy some cheap arse floodlights off amazon.

LEDs rarely burn out,

The individual diodes rarely burn out, but the power modules on them burn out all the time in which case you have to buy a new light.

I have no less than 10 LED bulbs with the module burned up in them in the last 5 - 7 yrs

LED bulbs don't really burn out like that. You usually have something internal that will cause them to go bad. You're better off replacing the fixture.
2-Light White Outdoor Integrated LED Wall or Eave Mount Flood Light

The light has two wires, red and black. That indicates it is a dc circuit. Yeah, I know led lights are dc only, just pointing out the obvious. Since all the lights started dimming first, then went out, indicates the system has a central transformer. That transformer probably has the photo cell on it as well. Replace that transformer box, it will be ac powered so find the correct breaker, and your problem will be solved.
