Just this, the taillight bracket Low to plastic. The soft Phillips set screw for tightening of the cable tie holding the required mounting pressure not stand. I used a matching Phillips screwdriver. Nevertheless, the Phillips is gone. I can not even adjust the bracket break down again without pliers.
That was better resolved at the front light bracket. Here you have to dispense with the Phillips and instead used a normal slot. Although is as a soft material, but holds up better.
I just wonder why you can return light vertically change / adjust. But the vertical angle of the front light must be set firmly. Most to build the Lampenset in the day and can not determine where the light beam passes. If you want to change the vertical angle, you have in the dark, loosen the grub screw previously described again and correct the angle. Not to mention should be that you can change the front light horizontally within bestimmterr limits.
Now my nightly correction is still pending. Let us hope that the light behavior is adequate for the price at least. the brackets are not anyway.
