It is and I had my mechanic do it, if it wasn't done properly ie it wasn't connected properly then i would think it should throw a fault 24/7 but its intermittent. Like I will go to my car switch it on no warning lights, start indicating works normally then trips out error code and flashes fast. Then i indicate the other way and same thing happens. Then I'll pull over switch the car off and on and the problem is gone and im driving normally.
I wonder it might be because the headlights are really dusty, it might have be from the bang average spray job done on the car or because the car was driven on dirt roads pretty frequently. Do you think it might be possible theres so much dirt that its stopping a bulb making contact and causing it to throw codes?
