Actually what I meant was that many times a bad ground in a front socket or even a shorted element in the bulb can make the turn signal indicator on the dash lite up but not when the turn signal is turned on but when the lites (park or headlites) are turned on. What happens it the park bulb has no ground and will look for a ground by backfeeding up the turn signal dash indicator circuit and finding a ground liteing up the Turn signal ind on the dash. So if a signal indicator lites on the dash with the lites on you may have a ground in that front circuit. Thats all I meant and even it the ind dont come on you could still have a ground problem. Ron
