Whelen Super Strobe Base Question

[348]

I recently acquired 2 Whelen Super Strobe model SS-361 Strobe beacons. As I looked inside the cast metal bases I saw what appears to be something molded into the base that looks like it holds some cylindrical shaped objects. Does anyone know what purpose this serves?

The same base was used for SS360 with internal power supply. These held the capacitors for the power supply.

I wondered if that might have been the case. Thanks for the confirmation.
