Hi guys, I was wondering if you could help. I’ve just replaced a small plastic pir sensor light from outside my door. The old lamp I removed only had a live and neutral but worked but it wasn’t pir controlled. I’ve wired the live and neutral into my new one and I can hear the sensor clicking but not getting the light to come on. There’s another space for a L1 which I guess is this switching wire that everyone meantions ? Do I need this for it to work because I do have 240v going into the lamp? Cheers in advance
