16: Altezza Tail Lights
Another fad that picked up a lot of steam in the 2000s was Altezza Taillights. These European-influenced taillights were transparent and looked different compared to other taillights on the road. Originally introduced on the Lexus IS300, they soon became an upgrade for all cars. Fortunately, like with most fads, it just went too far and the uniqueness of these accessories died off.

Nowadays Altezza tail lights look like a cheap upgrade, yet you’ll still see them stuffed on everything from a Silverado to a Civic. Drivers still buy them but it’s not close to the fad that it once was at the start of the new millennium. Altezza tail lights are a definite no-no when it comes to customizing your car or truck right now.
