Unrealistic landing lights

[homayoon hakimi 0]

Hi

Why most Carenado aircraft landing lights work inefficient and unrealistic? I mean they start illuminating the runway from nothing, all of a sudden just after touch down which is useless. 

Carenado Bonanza has a good landing light but most of pipers and other products not. Arent they supposed to illuminate the rwy way before landing so to guide pilots to land? 

is there any way to adjust them? Can we change the angle or type of lights in a cfg file? Can we use lighting file of another aircraft installing it to the one we want to our own satisfaction while keeping it private and never share the file?

I have taken screen shots but unfortunately can not attach the her!  

Thank you
