Iv'e had my LED fogs for quite awhile now and noticed that one was more purple than the other which is white. Pulled it out and noticed that one of the smd's is burned out and the others are real dull, while two smd's are really bright and have a purple color to them. I reconnected them to see if it was a bad connection and they seemed to match again. Now 3 hours later its gone back to being purple. Anyone know if its time for new LED's?
