ok I'm back on this now that I've sourced my CSL reps.
was thinking, what about just tinting the whole headlight lens black? see below link where a similar job was done.

wasn't sure whether the orange will come thru though.
anyone tried this?
also wondering whether it will look right on my sterling grey e85-its looks great on a black car. I'm going to fit some black CSL reps too.
