extra light wiring advice

hi decided to eventually wire my spots on my disco 2 v8,all wiring relays extra done,bit i would like advice on iswhere is best and easyist to get live 12v supply to my switch and where to put switch,i see some people say about using cruise switch plus light switch to go in binnacle.but this seems to be about£50 pounds worth,abit worrid about cutting into wiring incase i get it wrong and alarms ,windows,daughters hair straighteners go off,
thanks for any help

spots on with full beam? easiest way is to hook into the headlight full beam feed.

you can buy lil adapters that piggy back, so no wire cutting involved

Defender heated seat switch, the blank top off the hole you use, and engrave a light symbol

Thanks for info cheers

I got a rear wiper switch from a breakers for next to nothing, wrong picture on it but I know what it does,

You can use the front face off a front fog light switch on the rear wiper switch to make it look more obvious what it does
