PO put them on my car. I like them, I think it looks badass. Though, most of my friends bust my balls pretty bad for it. I think they do it because in all reality, any aspect of their car doesn't even compare to mine, so it's an easy way for them to bite me.
Only thing I don't like about them is that they slow down the front turn signals to a point where it's probably dangerous in some situations.. Oh well, what are you gonna do
Fords have a long history of sequential turn signals and were the first ones to do it
From an article on the interweb which is BS because Shelbys had it WAY before Cougars:
Pity the Mustang nut who finds himself jealous of corporate-cousin Cougar at Lincoln-Mercury. Cougars got all of those nice luxury items that were well outside the beer-and-pretzel Mustang budget. One example of luxury was the sequential turn signals and brake lights that made the Cougar distinctive. When they were new, these taillights sequenced with an attitude of luxury.
got my kit for less then $100 bucks and within an hour had them installed. its one the coolest mods i've done yet and always have people say how cool it is.
I love mine too.. I have them on the convertible. I enjoy being at an intersection and seeing people in the rear view mirror pointing at the back of the car and smiling.
