Once my blood/alcohol ration is down tomorrow I'll probably have to admit I should have left the arithmetic until morning but I think you'd do better to leave at least one diode out of each chain. That way the array will cope better with voltage fluctuations due to the indicators etc. It'll also protect the LEDs because the forward voltage drop varies with temperature.
Also, I don't want to be behind you when you apply the brake at night... so far as I can estimate that's going to be about 6x as bright as two 21w bulbs. Bearable in daylight perhaps, but overkill in the dark surely?
