Mustang Fitment: 1999-2004 Mustang GT & Mach 1

Fitment Note: Only use factory style or OEM replacement bulbs. Aftermarket Xenon or HID style bulbs will melt the fog light housings.

Item # SDT-15200GWJ
What’s up everybody? Landan with Late Model Restoration. Today this video will cover my overview and install on SVE’s smoked fog light kit fitting all 1999 to 2004 GT or Mach 1 Mustangs.

If you’re in the market to replace a damaged, cloudy or missing factory fog light in your 99 to 04 GT or Mach 1, but want to add a little bit modern styling; then this is smoked fog light kit from SVE is a good choice.

Right out of the box, they’re going to include everything you need to install them minus the attaching hardware; which is reused. They do feature a chrome inner reflector and chrome inner housing. The light itself will also be pre-installed into the plastic bracket which also incorporates an adjusting screw so you can fine tune the light trajectory.

They are a direct fit replacement fog light which means no modifications are required to make them fit. These SVE smoked fog lights are DOT compliant and legal for street use. In the box will be a driver side fog light, passenger side fog light, as well as pre-installed halogen bulbs.

SVE’s smoked fog lights are backed by a one year limited warranty which are warranted to be free from defects in materials and workmanship. It is recommended that you use a factory style or OEM replacement bulb in these fog lights. Some aftermarket Xenon and HID kits can’t melt the housings which would void the limited warranty.

Installation is a breeze and it does help if you jack up the front of the car for a little more work room.

Disconnect the negative battery cable.

It doesn’t matter which side you start on so just choose aside and remove the lower retaining screw with a 7mm nut driver.

Then remove the two upper retaining screws on top of the fog light assembly.

Once those are removed, disconnect the electrical connection and remove the light.
Transfer the small speed nut from the factory light to the new SVE light.

Remove the plastic film from the SVE light.

Position the light into place and loosely tighten one of the upper retaining screws.

Let the light lean at angle so you can easily reinstall the other upper retaining screw.

Loosely tighten this one as well.

Now you can reinstall and fully tighten the lower screw.

Fully tighten the two upper screws and then plug in the electrical connection.

Reconnect the negative battery cable and test for operation.

Double check your work and you’re all finished.

All in all guys, this install can easily be completed in about thirty minutes and as you can see here on this 2000 Mustang GT, it made a world of difference and even matches the SVE factory tinted headlights that are already in this car.
