Outdoor Court Lights Malfunctioning
Posted on 8/10/25 at 8:31 pm

Recently the lights on our outdoor courts started doing this. They're on a timer but it's shut off most of the time to conserve energy. I'm not exactly sure when this malfunction started but it happens every time I turn them on now. Anyone with experience gotta clue about what's going on here. I've already ruled out Gremlins, Poltergeist, & the Upaise Down.
Just incase image doesn't load.

Could be a wiring, transformer, or, if they are LED lights, bad driver circuits issue. Without having more specifics on the components of the system it's difficult to say.

Looks like you scored a touchdown

I have to assume these are LED lights, as I have seen a couple of gas station’s canopy lights doing this.
I think it would be cool th try to play tennis with that shite going on!

Thanks. That's a good list to start troubleshooting. Going to check out the driver first.

How are they wired up? Just a 120V AC circuit on a common timer or are they low voltage? Only way you can check the LED circuitry is with an oscilloscope or a dedicated tester. Also, what kind of timer and is it compatible with LED lights? I've run into similar issues with low voltage landscape lights when someone switched from halogen to LED's without changing out the transformer.

Thanks for that input. You might be right about the low voltage situation. If I remember correctly, the old lights were halogen or HPS and the new ones are LED. That's something else il'l check.
Is changing out a transformer a DIY job?

Entirely depends on the system, for regular low-voltage systems it's very easy.

I dont see why they would have one but the only time I’ve seen this is when a light sensor is malfunctioning.
It gets dark, the sensor lets the light come on, the light turns on the sensor thinks it day time, so the light turns off again. Could be a bad sensor or just needs adjustment.
Again I don’t see why court lights with a timer would have this in the first place.

Some older electronic timers are designed for purely resistive loads, LEDs are inductive. It's also why if you have older dimmer switches, they also need to be changed out when going to LED bulbs otherwise you'll hear a high pitched whine and the switch will get hotter than it should.

Can you determine anything by these pics?

Besides looking a bit rough and a set of trippers sitting in the bottom beneath that insulation panel, not much. Those are pretty simple mechanical timers, they don't care what they are connected to so shouldn't inherently cause a problem with LED lights. If you are comfortable with electrical work, know how to use a clamp meter, you could check the wiring and connections for damage or corrosion. If that timer is old, a new one isn't that much. It looks like it's in a location that can catch a tennis ball hit, not ideal either.
