Today I solved my problem.
This is a problem of cover.
The superior part does not coincide with the Lower Tier part, there was such a gap between the two parts.
I replace the track on which slides the two parties, i has no more space and light display works very well now cover.
I think it is a kind of sensor when both parties are not good compatibility between them the light does not work very well.
