    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    -The "bulb" is somewhat T10 based
    -It has nine SMD LED's

    Cons:

    -Polarity must be checked before plugging in
    -Gets hot after a short period of time using
    -Price/Quality is poor
    -The "bulb" is twice as long as an original W5W bulb
    -The bottom piece is loose and you have to make sure if the bulb makes contact
    -Light output is not that strong for a "100-lumen" bulb

    OtherThoughts:

    I measured that one bulb takes 116 mA with 12,28 V, so that makes the bulb a 1,4 W one, NOT 3 W AS PROMISED.
    Also the light output is exaggerated, I think it puts out about 20-30 lumens.
    As an LED product, this thing gets REALLY hot, and after 15 seconds of testing the bulb, my thermometer gave a 52 degrees Celsius reading. That tells me these little puppies aren't going to last longer than the original incadescent W5W ones.

    Bottomline:

    If you want "cool white" -looking parking lights, this could be your deal.
    HOWEVER if your car has a self-diagnostic system, these bulbs will give you trouble.
