thatll be me! i did them last year, bought the hella clear rears,
you need to remove the orange bulb covers which are welded inside the lights, for this you need a steady hand and a soldering iron, chop the bulb covers into 4 pieces and pull out of the hole with some pliers or similar, this is the hardest part but make sure you dont touch the clear part of the lights with the soldering iron or it will be seen from the front!
2 tins of red folia tec red tint from hellfrauds (£15 quid a can!!) a spot of masking and 3-4 nice flat coats!
but dont go on two heavy and make sure you leave it 10 mins between coats to flash off.
anyway heres some pics, they really do look factory.
