Headlight location.

[TheArf]

Sorry if this has been done before but I am at the planning stage and I am unsure where I want to locate the headlight arms.
I have looked at quite a few builds and it seems most have mounted them in line with the shock mounts.
Question, is there anything in the iva stating a minimum distance back from the front of the car as there is with a max distance in from the widest point of the car, and is there anything wrong with mounting them nearer the front frame.
I am working on a design to mount the headlights and indicators together and if I can move them forward it will help with the 45 degree of vision for the indicators.
