The lamps start after about 30 minutes at ever shorter distance the flash. They are useless ... minus 4 stars ...

The flashing is caused by the heat generation. Test operation at bar. 12V power supply and open cut even led to a high heat generation, but through the open test mode flash no. The LED lamp is not suitable for the mobile home because there occur higher voltage fluctuations and hence higher heat, which then leads to the failure of the lamp. Anyone who can read and wants a clear advantage: The description also has only a fixed voltage of 12 volts. So 1 star I give back.
