Do these have a blinking green or red light to show they're working properly?

No. The model we had for many years was better than this one. I think this one has really been cost reduced.

I'm pretty sure it's not, mine started off red, then went green when charged. After 2 weeks of use it blinked red then stopped working altogether, I'm pretty sure one of the inner connections is loose/broken.

they light up as red, orange and then green. there is also a lot of red and green on the board. so unfortunately, i would say to keep looking. Sorry. It's a great board though otherwise.

I think it tells you if the unit is charged [green light] or not [red] but I can't test mine right now because it is charged.

The colors are red, amber, and green. First hit the number gets a green lit light, second Amber third is red when closed the out. Could possibly present a problem if you couldn't make out the difference

No, they do not. Just a small green light that shows that power is on. But they are great when he power goes and it is after dark!

Ours has the red and green lights. I wonder if you have a problem with your power source?

The light turns from RED to GREEN. I don't recall how long it took to charge them. It must have been a normal amount of time or I would have remembered.

They blink one at a time until all four LED's are constantly lit. This lets you know when it is fully charged up.

Same here. They just stopped working for me a week ago. Green light is on showing a full charge, but that's it.

They blink depending upon the level of current charge. When it is fully charged they all stay on.

The light on top was alternating red/green. I thought it might mean the batteries, but I checked & they are fully charged.Now, I can't get it to work at all, no lights, no pump, nothing...yes, the batteries are installed correctly. Any ideas?

Mine still has the blinking light. I have the exact same one I bought two years ago, and this one I just bought a month ago. Both blink.

It is red when the batteries are not fully charged. Mine turn green when they are fully charged.

one of the lights is blinking and once the battery is fully charged the light turns green!

Blinking charge light starts with blinking Amber-blinking blue-blinking green to solid green, that indicates full charge!
