Those headlights look the nuts
Im currently looking into replacement lenses for the J-Spec headlights, aiming for an alternative lens that doesnt yellow.
A friend of a friend has a company that creates plastic products for motorsport. He thinks it would be possible to replicate the lenses with the beam scatter pattern so they'd be MOT friendly, but talks are at an early stage...and I've yet to source a battered pair of headlights on ebay for prototyping
Having read peoples comments on the possbility of CF inners for the headlights (and rears too), I may (once I've got my hands on a set of spare lights) look at the likelihood of being able to produce them (vac formed and autoclaved for 'bling' appearance).
