Neill,

I don't have any photo's to add but here is a link that might be of interest.

This map overlays data derived from weather satellites (DMSP) onto a Google map.  It think it's an accurate representation of the light pollution in Tehachapi relative to Bakersfield or Lancaster/Palmdale.  It also highlights the effect of the prison, which has it's own red spot on the map.  It's interesting to note that the yellow area goes east of Tehachapi where there are few residences or businesses.  This is from the Monolith Cement Plant.  I'd also point out that the yellow area does not go into Bear Valley Springs, a testanment to the Environmental Control Committee (ECC) overlords that regulate light output from the relatively large number of houses there.

Based solely on this data, I'd say the local light pollution is more a result of wasteful businesses and the CCI, not the residences in Golden Hills, BVS, Stallion Springs, or otherwise. 

I want to make a point concerning light from businesses.  Many illuminate their parking lots with lots of light.  That can't be argued even if it does seem glaring from below.  What I consider evil (ok, very poor manners and wasteful) is when those lights are not properly baffled and let light go out to the sides and worse upwards.  Those businesses that waste energy and create a glow in the sky are the ones that should be the focus for any light pollution mitigation efforts.
