As far as we know the Sonar (aka Spyder) and KS (Anzo) brand tail lights on our website are all street legal as mandated by federal law in the United States. This basically means that they are designed to the specifications set forth by the DOT (United States Department of Transportation). Occasionally, DOT might test models for compliance. If any BMW 330ci taillights fail (rare) DOT will have the companies issue a recall. For those tail lens, you can return them to us for a refund. For any other brands besides Sonar (aka Spyder) and KS (aka Anzo), we can not guarantee DOT compliance. Also, please be advised that your local laws that may disallow these sorts of taillights to be used.
BMW 330ci LED Taillights are a slick high tech upgrade for old or worn out stock tail lights on your 330ci. L.E.D. taillights are the newest type of tail lights available, and they use super bright and fast acting LED’s to give your 330ci the look of the newer high end vehicles on the road. With a relatively simple installation, you could enjoy the benefits of faster light response time as well as increasing the visibility of your signaling and braking. Best of all, 330ci L.E.D tail lamps give you a clean look similar to the red⁄clear style of taillights, with the same type of aggressive styling found on Altezza tails. Also, due to their bulb-less design, they are more resistant to leaking and fogging up than the other styles of tailllamps available.
While smoking your BMW 330ci taillights (tinting them) is certainly possible through the use of carefully applied spray tint (use light even coats), doing so may make them too dark to be legal. Please check your local laws as well as smoked BMW 330ci taillights of any darkness might be illegal in your area.
