Mars lights

[astapleford]

I want to add lights to my D&RGW F7 diesel. The Rio Grande typically had 2 headlights on their diesels.

Which light was the Mars (flashing type) light.....the lower one (on the nose door), or the upper one? I seem to think that the lower one was the "steady" headlight, and the upper one was the Mars. Also, was this standard for all railroads with 2 front lights?

Thanks for any info.

Thank you, Frank. Great info on these lights, Mars and Gyrolite.

Below is a website I ran onto that, D&RGW fans especially may find very interesting.

I believe it is the upper housing.

According to the DRGW web site, in the cowled passenger units, such as the FT, F3, F5, F7, and F9, the Mars light occupied the upper socket, while the fixed headlight occupied the lower socket. On hooded road diesels so equipped (GP30s, GP35s, GP40s, GP40-2s, SD40T-2s, and SD45s), the Mars light was mounted into the nose.
