I've taken the photo of the interior lamp assembly as I wanted to confirm the bulb type and size. It is 31mm festoon type and power consumption is not 10 watts but 8 watts. However compare to 0.5 watts by led type, it's huge power hungry system, yeah you might say 10 watts is not a big deal, but leaving the car with 10 watts per hour overnight might cause a flat battery when it is near at the end of its life spectrum.
Now I have to select either 6 led type or 12 led type. Just wondering 12 led type might not fit the housing so I rather choose 6 led type.
