headlight flashing help?

My left headlight flashes, I turn off the lamp 3-5 seconds. Then I open again, it freezes back to normal, why does it
Do you have this experience, sometimes it is not horn? (xenon headlight on vehicle)

It can do from the balance, but firstly, insert the connections and reconnect it.

The ballast is broken, most likely it was not burning in me, both of them, then we put on a new ballast burned then disassembled we put on their ballast this time it burned, it went out like yours, then I dismantled it

His warranty is standing, if it is related to him, let me change it with zero product then ... It turns out to be like a selector
When I do not realize it is going out, I go single headlight, it does not suit the lion :)
