I'm new to Z cars and my 280Z is obviously to USA spec but I need the rear lights to have orange indicator lenses. I have read this thread but wasn't sure about orange bulbs in red lenses etc so I bought some UK spec rear lights but the red lenses are damaged. I then set about taking the units to pieces using a heat gun - very gently of course. The lenses are glued in and the heat gun melts the glue just enough to allow very, very careful levering out of the lenses. I then reassembled the new spec units using the same method - warm the glue, press in each lense and the glue resets. This also allowed me to clean the inside of the units as they were very dirty after 44 years.
