"Signal BR 4" DLS and "Signal BR 5" built-in, 3A and 4A respectively, with the just the position lights. Is this what you mean - the 2 small white lights that indicate a shunt or call-on route? These are the original models, very old now.
You will need the rule SetSignalExtendedRule, kuid2:47662:20002:3, to enable the position lights in a session.
You've found the ones with lunar lights or theatre boxes, I presume these are the VSR ones by Bloodnok, with the targets. These unfortunately do not have the position lights.
