The one on the left is the 29 yo original. The right is brand spanking! The question. Will removing that middle piece from the headlight allow it to be brighter? What is it's function? It obviously reflects the light from the bulb, onto the surrounds, so my guess it's to allow an even spread? Does it make it brighter? No, I don't want to experiment with these bits, as the results would be split and subjective.
