Selective yellow is a colour for automotive lamps, particularly headlamps and other road-illumination lamps, such as fog lamps. Under ECE regulations, headlamps were formerly permitted to be either white or selective yellow—in France, selective yellow was mandatory for all vehicles' road-illumination lamps until 1993.
The analysis highlights Art and Standards as prominent areas in the source structure around Selective yellow.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
