The sealed beam headlamps in my 300F are well over 35 years old. Although I rarely drive the car at night, when I do the light output is grossly inadequate. Do the old sealed beam lamps deteriorate with age or usage? If I were to replace them with something more modern (halogen?) is the wiring in the car adequate to supply the necessary power to the updated bulbs? Terry McTaggart
