Yes it is illegal, but depends if ROV/TP want to catch u anot,
if u change to those white lights for head lamp is actually ok, but
neon and blinker too obvious they most probably will ask u go
inspection, fine up to $600 more or less.
It is illegal to install as well even if u don't on it, during
inspection they can see mah, but if u juz finish inspection u can
install, then when no ROV/TP around etc. in east coast park, u can
on to attract gals. If like that shouldn't be a problem.
Juz dun on on expressway or when driving, if not sure kena caught
and fine...
