Could someone give the coordinates of the both front lights of a vehicle, please? I want to attach neons.

They differ from model to model. If you just need them for a single model, just test it, will be something around x_offset=1.0/-1.0, y_offset=2.0, z_offset=0
If you need them for all models, have fun testing them for all (which is not impossible, but takes some hours)
