Here is the fix. Remove the light, take out the screws that hold the inside together...the light comes apart very easily. When you have it open, take a small pair of diagonal wire cutters and snip just one of the blue LEDS out. As soon as you do, the other blue LED goes dark as well. The great result...the white light still operates normally with the switch....and no more blue alien landing lights causing insomnia.
I did this with all 3 dome lights in the bedroom of my Spartan fifth wheel today.
