Do they have a sensor so they illuminate at dusk?

No, they do not. You can purchase a separate water proof/ power cord with a dusk to dawn sensor, to use in conjunction with these lights.

yes. I have tried several other pond light systems and this one is by far superior.

Hello Joy;I'm sorry to say mine didn't. That doesn't mean you can't get or they have a sensor, it's just mine didn't have that feature. Sorry!

Hi, No, they have to be plugged in to light up and then unplugged to shut-down. I wish they did have a light sensor switch. On the other hand, it would be something else that could go wrong and prevent the system from lighting up if it malfunctioned.

No but you can dim them down or put them on full blast. I have mine hooked up to a timer so that when I enter the house at night I am not entering in total blackness.

Yes they do. Instead of having two separate elements they have two different brightness levels depending on the setting of Hi or Low beam.

Yes. There are two LEDs in each of the light. The LED in the middle section is somewhat dim and stays on after sundown, and the LED pointing downward is super bright and it only turns on when motion is detected.

No. There is a light sensor that controls the on/off of the light. That being said the sensor could be covered with something like black tape to trick the light to come on. A.

Yes. The 2 lights in the middle come on at dusk. When it detects motion the big bottom light comes on.

negative on that, they light up only when you turn on the lights at night. it would be nice if they did though

No, but the backup lights on my Expedition prove plenty of light to see at night. The camera has a fantastic color resolution! It's small size makes it look like a factory installation.

Hi - No they do not. You would have to remove the battery to shut them off at night. Sorry

no .... only dusk to darkness , and it only senses Body motion . ( if you are in the car it will not turn on till it senses body motion , when you get out of the car )

Yes, it has a photo day/night sensor, but you can disable it if you'd like. These lights do stay off during the day.

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!

No: You can get from Amazon a sensor that will fit in the light bulb socket that will make it Dawn to Dusk.

Yes, they have a light that illuminates when the trigger is engaged. Works well.

Mine are used in a fixture that uses a photo sensor to turn it on automatically after dark. For such an application, the answer is "Yes".

There is no switch on these. they come on at dusk till about 8 hours later after a sunny day.

No. I had to check and when the switch is up the light on the switch goes off. They only illuminate when they're in the down/off position.
