Added some LED foglights to my Fiesta ST today.
Items Needed:
1) Small Philips screwdriver
2) H11 Bulbs
3) Pair of rubber gloves
4) Jack or Ramps to elevate the car
Step 1 - Lift the car using a jack or ramps.
Step 2 - Removing the passenger side bulb is fairly easy, there is enough clearance to untwist the bulb without removing any covers. Turn it left to remove the bulb.
Step 3 - Removing the driver side bulb requires you to remove a single fastener to the fender liner for added clearance.
LED Bulb vs Halogen Bulb - As you can see the bulb on the left is much brighter than the halogen.
Final Results
