Some people actually wanted those purple and blue headlights at one time! The thing I love about LED is you can make them do anything. Need a side running light? 1W LED $1 chip from the electronics store, hook up some 12V. Dim them, very easy. Little heat, little energy used, very bright. Make them pulse, dance, strobe on and on via a controller chip. Never changed one in my house. The Next Gen LED tech will use lasers and I can only imagine what a pin-point spot light it will be able to make..LED's
