These are the LEDs that worked for me. They do dim as they are going off...

I added a, used off Ebay, second OEM incandescent fixture to the drive's side that is powered from the dome light.
I use red lights to save my night vision when I'm doing Astronomy. The above LEDs are almost too bright! I put tape on the end of the dome light so that the side lights are the only ones illuminated. I may need to turn the rear lights around backwards to lessen their brightness as well. I also like being able to just have one illuminate if I override the dome and second rear light with the three-way switch.
Now to tackle the approach lights via forscan... Fingers crossed!
