On other cars, the LED has a red or blue color and a bit recessed. You could also add a resistor or increase the value of the existing one, to dim it a bit.
I've already put together version 2 of my ambient lighting project using exactly that! I'll start a new thread on ambient lighting so as not to mess up this thread specific to the JDM OEM lighting
Yep, my guess is that there may be other area's of resistance somewhere in the electronics of the JDM console that isn't getting used the way you did it. The OP shot looks much dimmer then yours. I could be wrong but that would be my guess.
Could be, I guess there could be a resistor hidden in the casing of the overhead light, although the circuit board on the back of the LED includes what looks like SMD resistors
If anyone has the OEM part number to the JDM kit and or the install instructions in English I would love to take a look them.
Part number for CX-5 welcome illumination (red) is C832-V7-050

I used the CX-3 kit which uses white LEDs instead which is C851-V7-057
If your car has illuminated sill plates then you need the harness adapter too which is C830-V7-700
This is what I had to do when I installed my own ambient light (smd led purchased off ebay). I placed it in the cubby in front of shifter because I was worry about distractions while driving. Tapped into the radio dimmer wire.
I'm planning to do this one today too. I read a great tip online yesterday that you can dim/diffuse an LED by simply scuffing the surface with sandpaper and it does work! As I've said above I've fitted red LEDs to my overhead console now which make a much less distracting light and a nicer red glow over the center console area.
