pir's operating two circuits

[Richispark]

hi guys hope all are well,
I am looking to wire 17 lights over 60m either side down a driveway from 3 pir's but only have 2.5mm and 1.5mm singles. im wondering how I can wire both sides of lights as they are two circuits but both operating off the same pir's?
thank you

Generally I wouldn't design a circuit according to the cable or wire sizes I have in stock.

I'm not entirely understanding the layout you have but it sounds like you could do it using a contactor or two.

as a bonus the singles can be used as washing lines.

Aye and a length of trunking with a "V" cut across the end makes a champion clothes prop,.
