    I have very basic knowledge of electronic components but don't know circuit design.

    I have created a circuit of LEDs that is formed of 4 series LED by 11 parallel sets of 4. The LED are white 3.3v makeing 13.2v the max.

    The LEDs work just fine with 12v applied. The LED are being used in a vehicle that sends a pulse signal to "test" the circuit.

    The problem is that it flashes the LEDs where a standard bulb produces enough resistance? to not flash from the testing pulse.

    Do you have an idea for enhancing the LED circuit to "ignore" the pulse and work when 12v is fully applied? The pulse is like 2ms long. Thanks.

    It is a modification to brake lighting ... changing from a standard bulb to LED hopefully.

    That runs into our automotive guidelines -
    and we can't discuss it.

    You would be much better off purchasing a LED bulb from a parts store.
