Is the shown brake light with red LEDs on a black background compliant to the rules? If no, why not?

Front view of a rectangular grey brake-light panel carrying ten red circular LED markers in two horizontal rows of five, equally spaced. Horizontal centre-to-centre spacing between the first two LEDs is marked 20 mm; vertical row spacing is marked 18 mm. The panel height on the right is marked 30 mm, and a lower horizontal dimension marked 100 mm runs from the first LED column toward the right edge.
