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.

Gradient Hidden Light applied to the new Sonata DN8, which was reborn as the 8th generation in 2019, surprised the market with a new concept lamp that was not tried in the existing automobile lamp. This paper describes the process of developing a gradient hidden light that combines the worlds first half mirror and gradient lighting. The development of the worlds first ‘gradient hidden light’ gave Hyundai the opportunity to secure our unique lamp identity and prove our advanced R & D capabilities.
