Spotlight No.1:
A blue LED series had been canceled. Audit found that an LED was blown and had a short circuit. REPLACEMENT LEDs at Co ... er in electronic trade concerned and repaired the part itself.
Headlights No.2:
Power supply failure. No chance of replacement or repair.
Headlights No.3:
A blue LED row failed. Not yet investigated further.
Headlights No.4:
A blue LED array already dead longer, two more rows flicker always strong and even the lights will soon adjust. This would approximately half of the blue LEDs in this headlight inoperative.
Apparently, the blue LEDs are most at risk of failure, possibly due to high current. If an LED is broken, a group of six to eight LEDs is paralyzed because of the series connection of the same. It always starts with the fact that a series begins to flicker, it increases until the series at some point no longer lights up (within a few days). Repair is possible, if you can solder, since there REPLACEMENT LEDs easy to buy and you rankommt well connected to the LED panel.
However, I have written off the headlights. If I need that again, I hope that I get from other manufacturers more reliable goods.
