请教各位，原句是这样的
When a design uses small striping or other designs which appear bright, silver, white, or car colors (not black), special “sun loading” problems may be encountered on bright, sunny days at low sun angles with signal lighting of the vehicle facing the sun.  

这句话说的是什么意思？sun loading指的是什么？
