    Default Device to test a dash 3W lamp?

    one of my dash lamp does not lit. It looks fine and pretty new. How would you test it outside of the car?

    aiin't there a device out there pumping current at a specified Voltage and Wattage?

    Thanks

    a 12 V battery and 2 wires will do the trick or a multimeter

    Just stick the terminals on a 9v square battery it'll glow dimly - or as shogun suggests, a multimeter will suffice!

    Assume you have the dash out or you wouldnt know if it looks good or not. The back of the dash is marked with the wattage by each bulb. Swap it with one of the bulbs that DOES light and you will have your answer.

    you are sick.

    I have a multimeter. So I guess you would use it in link mode or whatever it is called. i.e. it bips if current flows from red to black (black to red?)
    I will buy a 12V battery for testing purpose anyway. sounds like fun.

    thx for the input

    you got it,you are checking for continuity,so resistance range .Place rterminals together and you get the bleep.Put terminals across the bulb and you will get a bleep if its good and silence if its bad.Check one of the good ones first to make sure you are doing it right
    Gone but not forgotten

    The multimeter will probably only beep if it thinks it's seeing no electrical resistance. The resistance of even a cold bulb (the resistance of the filament increases when the bulb is on) might be too high to get any beeps so you might get a false reading of the bulb.
