The smaller lights on any car may benefit from LED replacements due to less current draw but headlamps are a different story. Most LED lamp assemblies have clusters of LEDS which don't radiate light in the same way that the original incandescent bulbs did. This makes any current type of LED lamp ineffective for projection for distance of beam. They might be bright but they won't reach out there for distance like a bulb that was designed to be in an adjustable reflector. While a halogen bulb can be made to work well for distance to some degree, an LED still can't.
