Light bar roof mounts

So I'm in the process in making my own roof mounts. Does anyone know how far the light should stick out pass the windshield to reduce glare possibilities? I'm making a moc up right now and wanna know how far I need it to pass the windshield.

 

I can't believe no one has give you any input. I wish I could help. I have searched and searched for mounting brackets and can't find any. I am looking at the 50" curved light bar. If I can't find mounts I guess I won't buy one

 

relentless fab has some cured one.

I have everything. im just nervous to do it myself

 

They have to stick far enough forward to not hit the hood. But that distance depends on the light itself. If its a tight beam, not far.

The $100 mounts are overpriced by about $60.
