Two orange lights slowly pulsing in the distance.

Initially only one object was seen, a bright orange light which pulsed twice before disappearing. After about five minutes we witnessed what we believed to be the same object, brighter than before, shining in the same place it was initially seen. It pulsed once, shining for 1.5-2 seconds, then a second orange light appeared next to it, pulsed once in the same manner, after which the first light pulsed a second time. They repeated this process twice more and then both shone brightly for half a second before fading away. No further visual contact.
