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