I'm not sure what type of lights you are after, but if you check the attached picture you will see some streetlights I have installed on a copy of Abel.wrp.
It shows Houdan at night from the air.
The lights are the modern sickly orange streetlights we have to put up with these days in real life, there is also a white version at the fuel station in Houdan.
These lights do not light up half the island, they have a more realistic spread of illumination.
Now, the lights you see on that picture are 'Streetlight' simulation, which means they are incorporated into the .wrp file.
I do also have some similar lights based on the 'Fire' simulation for use in the Mission Editor.
If you want the 'Fire' simulation lights I can easily email the file to you.
It is only a config.cpp in its own pbo, no extra model files are required as it uses the standard BIS lamp models, it only alters the colours for these variants.
Installation is simply to put the pbo in your standard Addons folder.
