Overview: Integrated design of built-in ignition coil of HID ballast: 1. Output open circuit protection: automatically take protective measures within 1s; 2. Output short circuit protection: automatically take protective measures within 1s; 3. Waterproof, heat-resistant, shock-proof, anti-electronic interference, constant power output; 4. Poor environmental functions such as high temperature resistance; 5. Good electromagnetic radiation anti-interference function; 6. Excellent constant power output design to adapt to wider light and extend the service life by 50%; 7. Open the switch view: it still works after 100,000 or more; 8. Lighting switch view: after 200,000 times of switching or more, it can work well It can solve the car warnings of most cars,...Almost 99% of the car departments can solve it.
