Where (back) is Light, is also shadow

I do what the previous speakers in terms brightness and visibility only agree. The design stands out also a welcome change from the other taillights. What I do have to complain about and the security aspect is concerned that at the lights after one minute turns off the parking lights and not as promised according to the description which upholds 4 minutes. Especially with the onset of autumn and winter. For the price there are better taillights. I would like to receive this taillight probably will not buy it again.
