    Who is good with electic/ wiring/ resistors?

    ive ordered Some SMD and id plan to fit them all over.

    But the main point it do i need resistors on them adding them to a 12v circuit.

    Technical Spec
    Source Material: InGaN
    Emitting Colour: UV
    Emitting Wavelength (nm): 400-410
    Size: 1.2 x 0.8 mm
    Intensity (mcd): 60-100
    Viewing Angle (deg): 120
    Forward Voltage (mA): 3.0-3.6
    Forward Current (V): 20-30

    Do i need any? if so how do you know, please tell me, i know a little bout resistors, but i dont know how you know if you need them or not.

    Should be ok going by that voltage, no need for resistors.
    You do realise how small they are?

    ok ill try without resistors.

    yeah i know there really small.

    and nope not for steering wheel controls.

    Forward Voltage (mA): 3.0-3.6
    Forward Current (V): 20-30

    They should be
    Forward Voltage (V): 3.0-3.6
    Forward Current (mA): 20-30

    if you ask me...

    dont worry, i knkew they were smal, didnt realise they was that small! 1.2mm x 0.8mm. i cant do nothign with that. need some bigger ones.

    Yeah you would not need resistors but really if your wiring them up to a 12V supply you wont get much light or intensity as they are more designed for 20-30V.

    +1

    Voltage measured in Volts
    Current measured in amps

    3v is pretty much the standard for LED's so a resistor would be needed. Possibly get away without one though if you was to wire them up in blocks of 4, although you will probably find the 1st one is brighter than the rest.
