Abstract
This paper discusses the use of a new double filament light source in reflector optic designs of headlamps for ECE and US VOA applications. An explanation of the development of the bulb is offered and the unique features intrinsic are examined. Methodology for using this source to produce low glare and a sharp gradient cut-off in headlamps is discussed. Factors, which must be taken into consideration with this new bulb, are presented for review. Experimental results of the bulb analysis and headlamp photometric performance are included.
