[38 coupe]

I have 6V halogen bulbs in the stock headlights in a 37 sedan. Along with bulbs I recommend replacement reflectors if your reflectors are tarnished. My lenses were yellowed with age that wouldn't scrub off so I also installed reproduction lenses. The combination of new lenses, reflectors, and halogen bulbs really makes the headlights work. Still looks good unlike the old sealed beam conversions.
