Hi guys , just bought a hella 12v/24v hella plug and cigarette adapter to with usb x2 for my led lights in cab , which socket would be better to use , 12v or 24v , and yes I am that bad regarding electrical stuff ■■? TIA
If your lights are 24v then plug in 24v if not then 12v… simples 
But remember not to plug any 12v stuff in if its on the 24v as it will go bang!!!
