2005 Chrysler 300 fog lights factory will not light

Electrical problem
2005 Chrysler 300 6 cyl Two Wheel Drive Automatic 44k miles

after checking bulbs switch and continuity lights still will not function. The dash indicator light says there on but they 're not, then after using a test light to check continuity the left socket appears to haave two ground circuits on i. Bulbs appear to be ingood condition even swapped on out did not change condition. The test light tells me that power is leaving the switch and getting to the socket.
