Ok, I see where I went wrong now. You're using the larger resistor to limit the brightness for the taillights and the brake lights bypasses it. Did you intentionally leave out the tail light resistor for the lower 3 rows of lights on the circuit board PDF?
Looking over the parts list, it appears that you've designed the LED current to be about 72ma@12.7V when the brake lights are activated. The spec sheet indicates the maximum forward DC current is 50ma and pulse current is 100ma. Since I see no PWM circuitry, I would suggest going up on the array resistors to dial the current down to below 50ma. 120 ohm resistors should work fine.
