BNSF searchlight signals can be connected to the Signalist SC1 as in the below diagrams.

BNSF twin head + single head searchlight connected to a SC1

Note that when using the CV38=8 configuration, flashing aspects can be achieved by toggling between the solid aspect and dark. Software such as JMRI will do this automatically.

In JMRI use DCC Signal Mast Decoder for CV38=76, CV38=77, CV38=132 and CV38=129. For CV38=8 use Double Output or Triple Output RGB for each head. Visit the JMRI BNSF-1996 signal system to see the available mast types.
