Hey guys one of the taillights is out on my s4 vert, just wondering before I go and change it tomorrow, Is this as simple as unscrewing the old blub and just replacing it with a new one? Or is it more complicated?

 

should be the same as a coupe so yeah it's simple. even replacing the whole tail light and harness with that is pretty straight forward. you shouldn't have any trouble good luck

 

How many rx7 owners does it take to unscrew a light bulb?

 

Depends.
I found the JDM bulb removal tool for a good price on eBay so I can change bulbs with only one assistant.
Before that though it normally took five people to do the job- one to hold the bulb and four to rotate the car.
