I bought altezzas, had them installed for about four months max, and then I ended up tossing them. Just don't like the look it gives nor the negative attention. Plus the build quality is horrible. You will always have problems with water leaking into the light and then condensation forms, killing the look even more. They're garbage through and through, IMO, and a ton of wasted money. Mine were like $170 when I first bought them, and now the same thing sells for like ~90. I wouldn't pay more than ten dollars for a set now.
not a fan of clears, euros, altezzas, etc. and i agree that color of the car plays a big role. -just my 2 cents. the worst has to be a lime green vw new beetle w/ those metroid-like pod looking altezza tails i see around town...yuck! there's a 4th gen. canarie yellow explorer by me w/ clear taillights, kinda weird. i had a vw jetta w/ the headlights taken apart w/ just the top and bottom painted black internally to give it a subtle phantom tinted look if anyone wants to get creative and try it w/ an explorer, might look good on a black explorer, but might take away from the lighting.
