Just ordered a frozen white metal for me and the misses, sadly my MP260 mountune Focus ST-3 will be going

Already got a set of eibachs lined up, possibly mountune MR155 but wondered if someone could point me in the direction of which LED bulbs i need for the rear, and sides and can i fit any in the footwells? in the Focus the plugs were there all i had todo was fit some nice red LED's
Anyways looks a really nice site, and hope you all have a great day!
