SAE 42V Exterior and Interior Lighting Cooperative Research Program Final Report RR-018

This research report documents the findings, the effects, and limitations of 42 volt electrical system architecture on vehicle exterior and interior lighting systems. The work covered in this report reflects the group's work to date which has focused on Pulse Width Modulation (PWM) control of 12V incandescent (filament) lamps from a 42V supply (the nominal voltage of a vehicle with a 36V battery under charge).

This report is the compilation of several "mini reports". Each test section includes methodology, analysis, results, discussion and detailed conclusions.

Chapters include:
