Can I wire in a standalone PIR to 2 external Lights?

Agentmatt

Hi All, 
At the moment I have a single light with PIR out the front which is wired to a switch just inside the door, which allows me to turn off the light completely or if I switch it off and then on again within 15 seconds it will stay on.  

I now want to replace the single light with two standard up/down lights and link them to a standalone PIR.  

Am I correct in thinking that the wiring would be either:
Option 1: 
Wire from Switch to PIR
Then
Wire from PIR splits into two and they go to light 1 and Light 2
***************
Options 2:
Wire from Switch to junction box.  Wire from box to PIR
Then
Wire from PIR splits into two and they go to light 1 and Light 2

I'm normally good with this stuff, but for some reason this is messing my head.  Must be lockdown madness.

Thanks All

Personally I would just wire light 1 to light 2  So 1 activates 2 and vice versa if both have inbuilt PIrs? But you could do option 1 depending on where standalone PIR is situated.

But there will be an expert along soon with correct setup.:)

The thing to check is the PIR has the capacity to operate the total wattage of your lights.  It will specify its max switching capacity - assuming your lights are LED I'm sure they'll be well within tolerance.  As to the wiring, it depends on what is easier, either splitting from the PIR or chaining (in parallel) from one light to the next.

Your two options sound the same, just with the inclusion of a junction box between the switch and PIR in option 2?

As per @ic but also check to see if the pir switching is for switched live or switched neutral.

I have 3 diffeently located pir sensors switching four lights wired in parallel ...but each are just 5watts each so only a nominal 20watts total load for any pir sensor.
