The body line of E90 with performance kit, I love it .... but urgly tail light of Pre-LCI it's unbearable. I tried to find the answer how to convert it instead of replace by LCI tail light and trunk lid. The answer was creating the straghit line on Pre-LCI of it.
I photoshoped several candidate for this and replaced Hella tail light (clear version) and visited my friend's shop named DSmotors and shown the design. It is not final version what I want to do from original idea but I still find chrome finisher to cover the straghit line looks like a 7 series.
Rear light is perfectly working and below photos are hella tail light and original idea of mine.
