The front yellow running lights (the two way blinker bulb/running light bulb) come on and off intermittantly. Both the right and left side behave the same way. The blinker works fine at all times. When i get out of the car and tap on the housing the bulb usually comes back on. Has anybody else had this problem. I am assuming it is in the wiring somewhere, but i could not pinpoint anything when i had the housings off.
