My traction control switch stopped working and i thought it might be the bulb. Ford says there is no replacement through them only the whole switch so i thought i might try some bulbs from radio shack and found #7219 micro lamps 12v 60mA with a wire-terminal base works perfectly. Cheap fix as its only about $1.50 for the bulbs. Once u take out the switch and see the bulb holders on the side of the switch it should be pretty self explanitory how to go about it. If anyone needs help with it let me know.
