Something about the following passage confuses me. It implies the beacon uses more power than the running lights. I would think the opposite. Obviously I'm wrong. Nonetheless, I was thinking that a beacon and the running lights are activated immediately after launch. If a backup beacon could be activated by the SAR team, it would help tremendously. It seems a pod is broadcasting and wasting power for a long time before someone is actually looking for it.“Yeah, but it looks bad,” she replied. Not only was there no beacon, but even the running lights designed to guide searchers visually to it were dead. Nor did their passives detect any EM signature from it at all.
Also, how do pods get launched empty?
I'd assume the beacon used more power. It's a radio transmitter trying to be easily detectable for thousands, if not a million+ km, possibly from within a field of debris where various discharging capacitors or damaged ships electronics are creating "loud" broad spectrum static (aka impromptu jamming).
Yes, a space probe in a quite star system can communicate with Earth using a transmitted with less than 25 watts of power. But only because Earth knows where it is and is using massive radio telescope arrays to listen to it; and it's not competing with any other nearyby radio sources. But even so, as I understand it, when the Deep Space Network needs to communicate back it has to use many kilowatts of tightly aimed power for the distant probe to receive and understand the signal. I'd expect an emergency beacon to be much closer to kilowatts than handfuls of watts in broadcast power.
OTOH the running light necessary to outline the pod to assist searchers in visually identifying it and safely docking, once they'd gotten close from following the beacon or investigating radar returns, don't need to use much power (and the Honorverse probably had even more energy efficient lighting that we do). A whole set of high efficiency running lights could probably run on less than 100 watts.
As for pods launching empty; I don't see offhand why a ship would deliberately do so. But battle damage might cause unintended activation of a pod's launching mechanism (or at least cause the locking mechanism to release so it drifts away). Or a nearby blast could literally rip the pod (possibly still docked to fragments of its launch mechanism) out of the ship.
