Here are the LED's I'm using in my RL.
Note, there are numerous other units that can be used with different prices and brightness.  I'm just listing what I'm using.
Use this information at your discretion!

All color is "Super White" or just "White".
All units are of type "194" or "T10" with the exception of the rear overhead door/map light which is 1 1/4" or 31mm festoon.
