2019-01-14 - Gurgaon (Haryana) (India) - Unknown

I saw two equidistant lights moving at absolute uniform speed in the same direction (North to South) at 0624 hours Indian standard time. These lights moved rapidly and the gap between them did not change. One light that was at the front was dim and the one at the back was very bright (as bright a venus at magnitude -4 or brighter). I know it was not a star or two planes or sattelite. I showed it to another person who agreed it was not a plane.I made a video of the object but the dim star couldn't be captured in the phone camera.

I checked Heavens Above mobile app and it shows ISS sighting at that time from NW to SW but that should have been only one light. So what was the second (dim) light in the front of bigger light? Can u please advise. Thanks ... FYI the distance between the two lights was constant and was nearly the same amount if distance that I saw between Venus and Jupiter in the SE sky an hour before the above sighting.

Also to inform you, I regularly keep track of stars and sattelites and use the above mobile app to help me in the sightings. I look forward to to hearing from you. Many thanks.
