Another picture recently resurfaced of my daily driver from the 1970s. You can see why my avatar pic was de-noised.
Rather than holding them back behind the windshield. let them overhang and possibly overlap the top of the windshield. Whichever light could be 2-3" lower. If the roof rises to the rear, it might not add any frontal area.
Placed at the corners the light will 'wrap around' things more; grouped in the center you'll get more shadows.
