if lead Headlight color gray and decide to go for the black color LED with out changing headlights to new one !?
is it possible to paint the internals of head light black?
has this been done before ? how easy or difficult to make?
not interested in black film on glass,
what are the options ??

 

I would not advise breaking the headlights apart.

However they do sale colored stickers that go on the outside of the headlights to cover up the ring.
