This SAE Recommended Practice applies to a decorative lamp(s) installed on the front of motor vehicles. This lamp(s) is intended only to be decorative and is not to impair the effectiveness of any required lighting device. This recommended practice establishes uniformity in use guidelines for the performance, installation, activation and switching of a front decorative lamp(s).
The subject of “Vehicle Signature/Accent Lighting” was brought up for discussion during the “New Business” portion of the September 17, 2014 Signaling and Marking Devices Standards Committee Meeting held in Sacramento, California. It was noted that some vehicle manufacturers had begun installing exterior lighting devices intended only to be decorative in nature on their vehicles. Examples at that time included white lighting elements on the front of vehicles with intensity levels greater than parking lamps, but lower than daytime running lamps. These lamps had sometimes been referred to as “signature lamps” or “accent lamps”. This type of lighting function was not covered by an SAE Recommended Practice or SAE Standard. The Signaling and Marking Devices Standards Committee agreed a Task Force should be established to pursue an SAE Recommended Practice for this subject.
