I can't tell from your photo if you have dual, quad style, or modular headlamps but they do degrade over time. You can buy street legal upgraded sealed beam halogen lamps which put out more lumens. Look at the back side of the lamps at night when they are on. The reflectors inside the lamp degrade as well as the lenses. If the reflectors are bad, light will spill out into the engine bay. If the seal between the reflector and the lens leaks, water gets inside the lamp and ruins the reflector.
