I'm at wits end with a burned out headlight on my 2005 Ford GT. The RF high and low beam works fine. 15 Amp fuse in position #17 is good. The 25Amp fuse in position #18 in the power distribution box is fine. I bought a new D1S headlight on Amazon, it looks identical to the Phillips OEM original and plugs into the OEM connector no problem. BIG PROBLEM. The headlight is still not operational. I have no idea what to do next. Any help here would be greatly appreciated. I'll pay for advice, By the way. Removing the inner fender panel is a real bear,
 
As I understand it, your headlight seems to be burned out. Does the side marker still work? The turn signal work? But pretty much if it is burned there is no bulb replacement. In any event, you will have to pull the fender liner to replace it so may as well do sooner than later. It will be much easier all the way around.
 
Have you checked to see if you have 12volts at the plug. What happened to the original light.
 
[B]fjpikul[/B], thanks for your response, The side marker lights and the turn signals work fine. There is power to the 25Amp fuse in position #18 in the power distribution box. I even swapped the two fuses between the left and right headlights, still no left headlight. I checked the connector that plugs into the ballast for power. There is no power. The ground side tests good. So the cable the powers the headlight goes into the headlight assembly, which is a sealed unit. From what I have heard, it's impossible to find a headlight, and if you can find one they are insanely expensive. Has anyone tried to wire in any type of headlight bulb, and power it on from a separate circuit. At least you would be able to drive legally at night.
 
I thought someone on the forum had figured out away to take the old headlights apart using low heat ,replacing the bulb and resealing the unit.

I don't think that worked to anyone's satisfaction. Headlights should be available and not as insanely expensive as they once were. Look on eBay. X2 Builders may have some or Northwoods GT. Try your Ford dealer or Unleashed tuning in Florida.
 
Fordpartsgiant lists new for$1350.00
 
Thanks for the tip on Fordpartsgiant.com. They list the RF for $1349.85, but the LF is listed as DISSCONTINUED. I'll call them today. Hope its just a backorder situation. Can anyone tell me what's actually "inside" the headlight that has failed requiring a complete replacement. I purchased the new Phillips bulb and ballast. it looks exactly like the OEM. It's just not getting any power. What exactly fails on these things?
 
Could this be a smart junction box issue? As far as other headlight issues... where is the guy that re-engineered the tail lights? :cool:
 
THANKS FOR ALL THE HELP HERE. I GUESS I'M JUST CURIOUS AS TO WHAT ACTUALLY FAILS INSIDE THE HEADLIGHT THAT REQUIRES A COMPLETE REPLACEMENT, AND NOT JUST A BULB AND BALAST.

I think Musk called on him to sort out some, "rapid disassembly" issues they're having.

Here is a pic of the bulb if it’s the one in question. This is from a new LH spare I have. I would highly recommend you check all the connections for corrosion.EEDC52A1-7B27-4B6E-8FD1-53E7A9F77E70.jpeg

Maybe it's a bad new part? Real quick test, "just" pull other working side apart and swap bulbs. lol
 
Check out SW Lights in CA. They are on Instagram and I have contact information if required. They open up all OEM lights and customize them. Probably can fix a Ford GT headlight. I’m good friends with the owners.
 
You also need to check if you are getting power from the two marked connectors. If not it’s not probably a fixture issue.5A7132AB-CBB8-443E-95FE-3129BF667433.jpeg

On the newer assemblies the headlight bulb is replaceable? When was the switchover made? Do you know the mfg date of your spare?

The OEM LH headlight out of the box was manufactured in 2005.
 
DM me, I have a new one in the box and also have a working one with cracked plastics ( RH side )
