Well, Norm your a bloody jinx haha
I checked all the bulbs just before I sent the reply this afternoon. Tonight, the right parker wouldn't light up. A gave it a tap with my knuckle and it lit up and continued to work. That would indicate bad earth or poor quality batten holders causing arcing/poor connection.
Will keep an eye on it
Maybe dielectric grease is worth a shot
Saw an 09 elantra this evening - blown right.
Max, I'm at 117k, owned since 92k, known the car since new - can never recall any bulb replaced
Good info about the pitting - I have always wondered if it was arcing causing it on other cars
