This is a reposting of a message from Bill Basden, I erroneously deleted it as it was in two forums. Sorry Bill here it is again….Charlie
EMD diesel Mars/Gyralights head lights
I am getting ready to install some lighting in my O scale models E3 E6 E7 E8
I have an official MP diagram book for diesels 1958. Now some things are not clear the way they word it.
Example
E3 Mars headlight—- pyle national 14″ lower—-Is the mars light a red and white ?
E6 Ply national gyralite —-pyle national 14″ white lower —Is the gyralite red amd white or white ?
E6 7100 pyle national gyralite—PN 14″ lite lower
E7 Mars headlight R&W pyle national 14″ white lower
E8 mars headlight R&W — Pyle national twin seal beam lower.
OK the 2 main questions are.
What is the difference from mars to gyralite?
Diagrams are labeled mars lights for the E3-E6 and E8 twin seal beam.
Now i could just say the all had mars lights and call it good to go. E 8 twin seal beam RW
Looks like when they made the diagrams who ever did them use some word license,
and then some one else comes along words it different.Thanks if you can help figure this out.

Mars lights and Gyralights were different. Here’s some information on the two I found.Gyralights

October 25, 2015 at 12:36 am #7384kenrisParticipantMars and Gyralite are trade names like Westinghouse and General Electric. Both companies provided various headlights, and oscillating lighting.
On the Missouri Pacific- Texas & Pacific lines, passenger diesels had a red oscillating light in the top light housing. The headlight was placed in the door. On early E units through E-7, the headlight was a single bulb with a large reflector. The red light was somewhat smaller since it had a separate housing that moved as a unit. The red light did not illuminate unless the train was stopped and discharging passengers. This would signal on-coming trains to stop. (actual rules may have varied by track and signal types. I’d read a rule book to be certain.)
On E-8 locomotives, most of the lighting was from Pyle-National. The head light in the door was now two sealed beam lights mounted horizontally. In the upper housing was a vertical twin beam unit with two oscillating lights. The lower light was red and served the function described above. The upper light was a white oscillating light used for alerting drivers that a high speed train was approaching. It was illuminated when the train was moving.
Based on photos in various books, earlier E-units were all eventually upgraded with the sealed beam units

Makes it more plain now, and gives me a direction to go with. When I get some of this wired up I will post photo’s
Will make for interesting viewing.
Here is a link for the company I use who has a vast assortment of lighting products,
you might want to check them out. It is all done using very tiny LED’s.http://www.ngineering.com/index.htm
Thanks again Dick.
