I installed a hid bixenon so i have hi and low beam the same as a standard bulb a year ago. It helps this old timer to see much better, at least 50% more light. It uses less power than the std bulb, but i ran a fused power line from the battery. Adjusted right there wont be anyone blinking lights at you. It cost me approx. $75 for the kit with the small ballast. Get the car kit and you will have a spare bulb and ballast.
