LEDs are improving at Moore's Law rate. Once LEDs can achieve illumination on parity with today's HIDs without requiring extensive heat sinking the industr...see more »Someone can correct me if I am wrong but no one made the old sealed-beam lights illegal and nothing prevents a manufacturer from using them.
