What’s not working yet? Power and Brightness (Lumen) Enough, but it’s not really Lux.
For other common headlights, the LED is fine. It is even more than satisfying. The H4 2 is still weak in terms of focus.
Of all the LED H4s we have tested so far, the low beam is not as good as the high beam, and the low beam is not as good as the high beam. Due to the LED PCB board structure, I think it is difficult to play with two lights.
It’s fine for a single lamp, but not for the faint-hearted LED H4.(In this age of ever-changing technology, I’m not happy about it now, but it will be fine later.)So far, the HID is the most recommended HID headlight.
If you’re not happy with the way things are going, then you have to make sure that you’ve got the right person for the right job.
