Unity Light problem?

HI All

I’m using for the past few months now I’m sitting under the task regarding lighting system.
This task I need to instantiate point lights in the position I place. The lights are instantiating properly but the problem is if I instantiate more than two lights dynamically at same y position and changing the x and z position more than two lights the lights are not visible can anyone tell me any solutions regarding this issue. In the below image I need to display more than 5 lights in the scene dynamically.

Thanks&Regards

In your Player Preferences > Quality Settings, increase the the ‘Pixel Light Count’. The default is 2.
