Can not be watertight because of "waterproof 100%", too little light

What is so annoying:

a) "waterproof 100%" is excluded because the threaded rods for fastening are hohlgebort for cable routing without sealing penetrates here the water. Furthermore, between the cover glass and the case I could air blowing with the mouth, then plays it safe and pure water, right?

b) The mounting hardware: nuts non-locking, no Sprengring.Schraubverbindungen in plastic contact that can not keep.

c) connector cable: The cable insulation with too little plasticizer, too rigid, assume that can break the isolation in sub-zero temperatures. The total cable too short. Connectors max. suitable for interior, no seal.

d) The relay: Not suitable for installation in humid rooms, "seal" is ... oh no idea what that should round rubber grommet in a square hole.

e) Now the lights: The design is really great, in the showroom when the car does not get wet, we make use of possibly only allowed the claim in brightness not be too high, with original daytime running light / factory delivery of what you so on the road looks can not keep the lights.

In short, even if I'd been given the lighting, I would not have this installed, hardly imagine that the lights only survive a winter.
