LED Industry Chaotic Phenomena:
 
1. E-mark and DOT certificate: For led automotive lighting, there is no industry standard of E-mark & DOT right now except for  LED Daytime Running Lights. 
 
2. LED Types: Led has many types, the parameter of which is complicated and rich. Without professional knowlege and equipment, most customers cannot still discriminate quality.
 
3. Quality: At present, many nonstandard small companies cannot guarantee the quality of their product if they don\'t have technical development team, productive facility and test equipment.
 
4. Price: The product quality is totally different, phenomenon is that the  same product between good and bad quality component has price big different.
 
5. Because of fierce trade competition, many companies have to break bottom line of quality and seize 

market with low price strategy in order to survive.
