but the smoked on the inside is on inside back piece, that wont effect light output will it?
Yess it will. ever notice how oncoming traffic's headlights seem to be one giant blub?
Thats because the light emmited from the bulb itself is reflecting around back and forth inside the housing, causing what you see as one big ass light..
Now if you black out that back ground, as oncoming traffic you will see just small lighted up dots. where the light is being emitted direclt from the bulb assembly. Think projectors, but not the same..
Theres a fairly drastic difference in perceived light output from the two.
Its ultimalty up to you what you do with your headlights.
But if I was you I would simply ask myself, "is my life worth some blacked out headlights"?
Cause thats exacly what your doing, when you reduce your headlight output to the point you cant see that blacked out car doing 30 in a 65, or that big ass deer about to jump in the road..
