I bought a pair of these but when I was installin' it, I noticed that this 1 has 5 sockets. My old tails came with only 4. What would you guys suggest I do? Should I go to an electrician to install a new bulb 4 the extra socket or should I just do it myself?
And if I am doin' it myself, how exactly do i go about doin' it?

This is what the tails look like.

 

well if only u have 4 lights in back ur either missing one or u got the wrong tail lenses

 

That's interestin'! You see the thing is, I'm from Trinidad and I guess they'd wire the same car differently when the make it for a particular country just like how they'd give it a different name. The protege's we have here are called 323's and familia in Japan. I have a familia 'cause I got mine from Japan & I just realised something. The 323 has 3 sockets, the familia has 4 and the protege has five. Correct me if I'm wrong about the pro.
