Mars Light castings for Proto SD-7

[dcdewi@a...]

I recently purchased a new HO scale Proto2000 CB&Q SD-7 #300 in the 
Blackbird scheme and have been trying to decide what details might 
need changing to make it more accurate.

Any suggestions?

I would like to add the raised mars lights on both ends but have not 
figured out who makes the correct light casting. Suggestions?

Thanks in advance for any help.
