HID systems during there time were very bright and I never had an issue with the systems at the time.. LED's have just surpassed them in terms of output (lumens) and overall burn time.. LED's are also much more reliable and there are so many choices for decent lighting systems that will not break the bank.. For years the name brand vendors have gotten use to charging 300.00+ for there high end systems..
LED's have provided an opportunity to buy at 1/3 the price and still be safe on the road.
