          E-MARK/DOT OE HID BULB OEM, Distributor WANTED        






We’re very pleased to inform you that our mercury-free D4 HID bulbs have been E-approved after months of continuous efforts.


The tests are conducted by Baoji Station, National Lighting Source Inspection Center(No. 17, Chuanshan Rd., Baoji City, China), the ONLY laboratory capable of doing the tests for gas discharge light source(HID) in accordance with ECE R99 in China, authorized by TÜV.


Following our E-approved D1 & D2 HID bulbs, we still stick to E13 and TÜV having concrete reputation and much more reliable in the industry, in comparison with some other E marks having their tests conducted in the applicant’s own lab.


Moreover, if you’re willing to work on this homologated/street-legal HID bulb with us, we would like to invite you to extend your trademark(s) to the certificate and distribute the bulb with brand(s) of your own.

The certificate extension for the very first time is totally free of charge; you should take good advantage of this opportunity.


Here’re just some of the vehicles with D4 headlights, for your information.
