Depending on how high you mount them, they could be seen virtually as far as the tri-color.
The benefit is that you can use the red-over-green configuration simultaneous with the deck lights (the Nav Regs do not permit use of the mast-top tri-color at the same time as the deck lights.) By using them simultaneously, you benefit from greater over-all visibility.
