Do the maths, atleast 4 long range top ones fitted in a arc to give you large area, two on the underside of the bumper for fogs, then atleast two on the A-bar to give you spots that are wired to your full beams
then you need ATLEAST two pointing back with a switch wired to the reversing lights so when your in that supermarket car park and some toser doesnt let you out of a space you light up his day
