If physical fitment is an issue for your car/truck/motorcycle, then this is the answer for you. Small body size makes this bulb fit in more than 90% of housings. 

No mechanical fans
No external drivers
No bulky heat sinks

Idea behind design of this light was to sacrifice a bit of power but instead give an LED option to installations that would not be possible with traditional LED bulbs having mechanical cooling systems. Smaller body size makes for easier fitment in DIY installations. If you have the room to fit a physically larger light you should consider the ELITE2 series.
