The quality of the taillights is apparently very good. However, I find it rather strange that you simply can not reconnect the cables in the rear light, but that one has to again an adapter plug (or equal to a whole harness) buy. This is called good "promotional". It is not enough to buy the tail light (unless you had previously also been the same thing). The backlight itself is good protected against the ingress of rain water because of the outlet (the back is completely closed), but now has the bayonet connector a grommet, into the theoretical water can penetrate. So you have gained nothing. In addition, you connect the cable to the bayonet connector is an adventure. There are Krimpklemmen that one then pushes into a plastic housing. This one never gets out again (inside is a hook tabs to which one can not access comes). Thus if you have a cable connected to wrong or oxidized later a terminal connection then you can not pull out the clip and edit. If you try them anyway surgically remove them is destroyed afterwards and you have to take a new (so it has because a). I do not know if there are individually these terminals. Otherwise you have to buy a complete bayonet connection again. In addition, the crimp on me is far too unsafe. I have soldered the cables to the Krimpen. One must again be extremely careful that no solder survives, otherwise no longer do you get the terminals in the housing.
The mounting of the rear light is not without. Since survives a connector with several centimeters in diameter at the rear, there must be corresponding place. For me only one thick sheet was without openings, so I first had to go with a conical drill milling inch hole.
Despite everything, the taillights of good quality. Everything works (also rear fog light and reverse gear). There were already all bulbs this (which alone already costs a lot).
