Yeah Altezzas refer to the style of taillight you have on the car.
Most Mustang owners think of them more as "tacky" rather than classy. They just call out way too much attention to them when it should be focused on other areas of your car, like wheels or those cool louvers.
But it's your car and if you like them then keep them on. I think you did a really good job with the looks department on your car even if i am not fond of the taillights.
If you go back to the stock style, maybe look into some sequential brake and turn signals for the rear.
