This study is low-cost HID headlamps. Total luminous flux of new 25W HID bulb is 2,000lumen. So we can make cost and weight reduction by omitting auto leveling system and headlamp cleaner. Through this study, by optimizing reflector, this new system make road illuminance performance better than 90% of 35W HID headlamps. Most test participants didn’t distinguish clearly illuminance performance between 25W HID headlamps and 35W. When comparing with H7 halogen headlamps as to a glare, there was no big difference.
