Justin Bieber's Fisker Karma Sports Car ... A Rolling Violation

Justin Bieber’s tricked out Fisker Karma sports car should have a bumper sticker that reads “Ticket Please”…'cause it’s chock full of violations…TMZ has learned -- but not for what you think.

The chromed out, $100 K, Bieber-mobile has been making appearances all over LA in the last few days …blinding drivers from its reflective paint job…but vehicle violation? No sir…just a gigantic, distracting pain in the ass.

Law enforcement sources tell us the real problem …the row of FUCHSIA lights hidden under Justin’s front grill. That’s right, in CA, the only lights you can legally have facing forward are white and amber...not The Biebs signature purple (below).

That’s not all…we’re also told Justin’s window tint is a little too tinty…also qualifying as a major no-no.

If caught Justin would be slapped with a 'fix-it ticket' citation.

Note to Bieber..reflective chrome is not subtle ... then again, neither is the car.
