Interestingly enough, I just took out my ‘05 for a quick drive and noticed my right turn signal on the dash was blinking faster than the left dash signal. After checking, I discovered the right front turn signal in the headlight is not working. This bums me out. Where can I find a replacement turn signal bulb and can it be replaced easily? Previous posts say yes but nothing definitively. Thanks.

Yes it is a common bulb. It is much easier to get at if you have a lift. You can go whole hog and remove the fender liner and the whole light assembly; OR drop the front spoiler and reach your arm and hand up behind the housing and twist the bun out a quarter turn. Unplug the wire first. Reverse the process to install the new bulb. If you have a copy of the Service Manual you can look up pics to see what to expect.

If I remember correctly, some people where able to get It working by whacking the housing with a flat hand.

I did a write up many years ago about the drivers side. That was complicated by the window washer reservoir. It should be here someplace on the Forum.

Thank you for the info. I looked in the system and saw that it’s pretty common. I will pick one up tomorrow and get it switched out. Thanks

It's a regular incandescent bulb, not an LED. Do not get fancy and try to substitute an LED. You will probably cause further blinker problems.

Also REPLACE the lamp. Dont take it out test it (fine) and fall for it, and put it back. I had to make the effort twice, as I only scuffed the connections (again tested fine with continuity tester), and didnt replace it. It worked for a little while, the new lamp has been fine a couple years.

The filament brakes, light goes out. You move/shake the bulb, free filament swings around and randomly re-attaches, light works again. Now the shorter filament with weak attachment usually burns brighter (lower resistance) for a short while then burns out permanently. Common with the C7 Christmas tree lights. Probably same thing happens when you smack the light.

I would have guessed that the C7 was new enough for LED’s.

I kept mine working for a while with the ole’ whacking the unit with my palm, but eventually replaced the bulb. Simple job, bulb available at any parts store

Just thought I would revive this thread to see if any progress has been made.

Bumping this thread as well to see if anyone has any thoughts about how to fix the lenses as it appears to have hairline cracks in the lenses and upgrade the light elements while I am at it so they work better. Driving at night is sketchy at speed.

I am in the middle of doing the LED upgrade..................or I should say, redoing it. I sent it to Lightwerkz, who I strongly advise against using.

I will post pictures in the coming weeks on how I fixed most of the eff-ups the Light specialty shop did.

Regarding the lens, it is actually not too difficult to remove the lens from the light chassis. after removing the peripheral screws, you can warm the entire assembly in an oven set at 240 degrees for 20 minutes and the lens will come off with a gentle lifting.

You can then polish (and I guess clear coat) the lens pretty easily.

one thing Lightwerkz did well is make a tutorial on how to do it;

This is my advice after almost 20 years: don't drive with the headlights on unless you have to at night.

Please keep us posted on the developments. Does anyone here on this forum offer a service to refinish the Ford GT lights and lenses?

Mine appear to have hairline cracks or are these just in the lenses and can be polished out?

SW Lights in California can refurb your Ford GT lights. I believe Sean has some in stock too.

Is Sean the owner of SW lights? Can anyone vouch for their services?
