Filament lamps do have a limited life. The filament will evaporate even if there is no vibration or thermal shock. More efficiant forms of lighting like LEDs and HID are supposed to last longer. One would expect the lights to outlive the car.
On our 2009 Chrysler 300c we had a dead red led highlevel brakelight And a HID headlamp. The expected life of well designed LEDs should be 100,ooo hours and 10,ooo hours can be estimated for the HID. The reliability of this high tech lighting appears well short of industrial high rel expectations.
Is car stuff driven harder and not designed for longivity? Is this a QA problem with subcontract manufacturing? Why are these lamps so bad, its not just Chrysler 300c, Its not only me.
