Find a used ballast for sale and replace it to see if that works. Hell I think I have one laying around.

 

same thing is happening to my 2011 G37. im still trying to figure it out

 

happens to me on my 09 g37 coupe. I have the projector lights with iron man leds. The projector light on my driver side will randomly go off and stay off then after a while it will go back to normal. I bought a new ballast cause my mechanic told me that's what it was but everytime I go to install it the light starts working again. I got a ballast for like 80 bucks on amazon btw. 500 is ridiculous

 

I think i have the normal lights the car came with! but i asked my mechanic if i should go to Infiniti since i have a good friendship with the service manager because i have bought in multiple cars from them and he said it will cost me like 1000$ screw that! and yes i have seen them on Amazon or eBay for 50-100$! did you install it yourself or did you go to a shop?

 

I am having my shop do it. Unless you really know what your doing I wouldn't mess with it.

 

update. shop installed new ballast and light works perfectly. lets hope it stays like that tho

 

 

I dont have a link handy, but the quick and short of it is, you need to remove your front bumper to get to the headlight, then remove light. The ballast is a metal box located on the bottom of the headlight housing. There are two versions of the ballast I know of. Both will work fine. Simply unplug, and unscrew ballast, and replace with new one.

 

 

Can I butt in and ask what are the two? I know you can eBay the OEM and OEM knockoffs. Are those the two you are talking about?

 

No, both ballast versions I've seen are oem. I'll try and get the specs on them if I can.

 

Awesome that would be great!

 

I have a 2009 G37S Sedan and I am having the same issue(s). I have replaced both bulbs and one ballast. It started on the right and then the left. The headlight will act like it wants to come on when I start my car, but then one side goes out. I turn my steering wheel switch back and forth and the light comes back on. I have had a headlight to stop working while driving. I replaced both lights and the left ballast and still have the issue. I have taken it to a local mechanic and they can't determine the issue.

 

I’m having the same problem but with my left one. I bought car used and the left headlight didn’t work. I bought new ballasts for both left and right along with the bulbs and it working for a couple weeks. Now the left one has stopped working again but if I switch the lights off and back on it flickers and turns on. Also the big problem is these hid are really dim like the factory ones were as well. So I wonder if I’m having a loose connection in a wire somewhere or dim is a normal thing with these cars?
