Future Application
At this time, most newer vehicles are using LEDs where incandescent technology was formerly utilized. This includes all indicator lights, turn signals, brake lights, reverse lights, in-cab lights; everything except for headlights.
LED technology has not been utilized in automotive headlights just yet, but expect to start seeing LEDs in headlights in the very near future as they have been undergoing development since 2004. LEDs already have proved their worth in the offroad industry where engineering factors such as glare and tight beam patterns are not of as much concern. VisionX is the leader in this industry. Partial and all-LED headlamps were factory installed on a select amount of 2008 and 2009 automotive vehicles. Current designs provide lower performance than HID headlamps. While LED headlamps are expected to someday surpass the performance of HID headlamps, limiting factors currently include high production costs, regulatory delays, engineering issues and uncertain performance.
