| The corners do that because the bulb in them is a dual filament bulb. One stage of the bulb is the constant(dim), then the 2nd stage of the bulb is the bright part when the bulb flashes. Most times when you upgrade corners to something clear, the bulb shines brighter, especially on corners like mine(sonar) where the lens is completely clear and not opaque like the other lenses.
