[DeTomaso] Headlights

[JEFFREY COBB]

True what you all say about reflector, filament and lamp design. 
The interface of all three are crucial to the lamps output lumens, pattern function and temperature.
Today a person can retrofit a Xenon bulb into a 1971 Euro designed light housing, which would have been designed for Type A, H-1, H-4 bulbs and have much better lamp than what the 1971 unit could have ever dreamed of producing.
Substitution of diff bulbs and reflectors can work but not all the time, most of the time a high powered bulb, example a H-4 130/160 w, a H-4 210 w single filament high beam bulb or H-1 130 or 160 w just will shotgun blast a massive blinding uncontrolled beam. 
LEDs are fantastic as long as the reflector and lens are designed as as team with the LED.

All other bulbs/ filaments are designed with a glowing filament or a glass bulb containing sodium 
which glows as a xenon, to have this glowing mass set correctly relative to filaments axis and the focal point of the reflector. 

LEDs are a fantastic light source that projects light off of a flat surface onward toward the object, to a reflector for an improved light beam pattern or through a lens that magnifies the LEDs output.
That is why you see so many different designed led bulbs to take the place of a halogen, most of the time if you can just find a company that locates the led bulb axis correctly and have enough lumens then you are in business.
