Sorry, no original Quallität

These taillights should my original DDR replace taillights. The appearance and the dimensions are the same. Unfortunately, not the quality.
The seal has fallen against the same. Whose meaning I did not understand without back because when screwed between the indicators and the rear light a gap opens up, where the water penetrates.
When unscrewing the lid it disintegrates into its component colors.
But the price is right.
