Problem with Two motion sensing lights in parallel

I have hooked up two motion sensing lights in parallel - the wiring goes from switch to receptacle 1 then to receptacle 2 (the first light is set up off a pigtail).

When I turn the switch on at night, the lights click on and off in sequence then neither motion sensor works.

Is there a problem with this setup? Do the motion sensors clash with each other or am I missing something here?

Thanks in advance for any tips.

If you read your manufacturer's instructions you should find that you are advised not to supposed to connect to motion detectors on the same switch. The design of the motion sensor lights allow you to turn you switch on and off rapidly to change mode from auto to off to constant on in that motion sensor flood light.

If you put two motion sensor flood lights on the same switch they will get confused and one motion sensor will be in one mode and the other motion sensor will be in a different mode because both motion sensors will not allways recongnize the rapid on and of with that same switch. One motion sensor will recognize a rapid on off of the switch and change mode but the second motion sensor will miss what the first sensor recognized then you have two motion sensor floods in two different modes.

Hope this helps

The instructions don't say that, but I see where you are coming from here. Any ideas short of getting rid of it?

Install a second switch that will shut off the second sensor flood separatley from the first thus having one switch for each flood. Then you can rapidly turn on and off the floods till you get the one with the second switch in the right mode then turn that second switch off so that you can get the first flood in the right mode without affecting the second flood's mode. Once you get them both in the right mode then you can turn on the second switch and you are back to normal. Only use the second switch to cut the hot conductor going to the second flood and only use that second switch when you need to get the two floods back in the same modes again. Cheap easy fix for an irritating mode problem.

Hope this helps
