LWRP lights are flicking in random position and distance

There is a problem in realtime Lights in LWRP , They are flicking sometimes I didnt understand why this happen. Maybe I miss something in quality settings ? Any idea or experience ? They are working as realtime in baked scene.

My unity version is 2018.3.2f.

Thanks.

You are most likely hitting a pixel light limit in your project. If you exceed that limit, some of your pixel lights will be converted to vertex lights instead.

Keep in mind that LWRP supports up to 4 pixel lights per object. You can verify your settings in LWRP asset, under the Lighting rollout.
