Significantly? Absolutely. The original tests were performed on fleet taxi cabs in New York and used both high mounted center lights and other, lower, third lights. The result was a reduction of rear enders by over a third. BUT, the statistical reductions consistently declined after the adoption of the regulations requiring the third lights! It has now dropped to under five percent reduction. How could this be? The answer is that the original reduction was not caused by the location of the light itself, but rather by the novelty. The fact that there was an unusual third light is what caused the significant decline. After people became used to seeing a third light in the back window it lost a large amount of its effectiveness. Having an unusual third light is now more effective than a CHMSL.

Trust me, I'm absolutely right on this.
