2012 infinity g37 where are the bulbs located to be changed out?

 

Assuming you mean the front turn signals, one of the easiest ways is to go through the wheel well. Removing the tire will give you more room to work, but not 100% needed.

 

You can go directly to both front turn signal bulb from the engine bay without removing a thing, I have a 2013 g37x, not sure if the setup is the exact same though. I have swapped mine out several times without moving a single thing going from the engine bay.

 

Is it the same for a coupe and a sedan?

 

I am not sure of that.

 

I have a 2013 sedan and I swapped these bulbs out last weekend. For the 2013, I don't think it's possible to access it from the wheel well?

Instead, I went under the hood and removed both air filters. Just need to unbolt it and loosen the clamp and slide it up.

FYI*The turn signal and parking light are the same for the 2013 models, in case it differs from the '12.

 

Go through wheel well or remove light housing
