XP10 night looks to dark to me and mainly because of the small amount of light that the street lights produce (Im talking about HDR lights when it lights other objects around).

Does any body know if there is any way that I can make the street lights to produce

More light and to light more surface and around?

Take a look at these. http://forums.x-pilot.com/files/file/435-replacement-day-and-night-lighting-lightstxt-for-x-plane-1020/

 

They are a set of replacement lights for HDR

I have this set and it's wonderful,but I'm talkig about hdr lightning when it lits other objects/streets,this effect IMO meeds to be stronger.
