Long post...
Lights arrived Monday and it took me a couple of days to get outside and try them. Here are the results.
I am replacing dual 1141 lights in my fixtures. I ordered these:
24-505036-12101. My 1141's, two lights, left and right.

2. Left- 1141, right-36-1210

3. Left- 1141, right- 24-5050

4. Left- 24-5050, right 36-1210

5. Two banks of all 1141's.

6. Front lights with 2, 36-1210, rear lights 2, 1141's.

Conclusion: (all subjective and my opinion only)
The 24-5050 looked green to me and my DW. These will end up in my basement storage.
The 36-1210 were very close to the natural 1141 color, maybe a shade more white (which we like), and seemed a little brighter.
**One out the four 1156 bases, one does not work so I will have to remove the hot glue and check the solder joint.
I really liked the 36-1210 and will be ordering 10 more (to start).
