Hi, sorry I could not reply to you since the forum's server has been busy on and off. Anyway, I got the red laminates from a shop doing body art at Autobacs Bukit Timah 2 yrs back. You should be able to get it from other body art shops too. After pasting on the white portions, I just use a penknife to trim out a rectangular box for the reverse lighting. Good luck.
