When on approach to Runway 33L the LED lights on the runway centerline for 33L; there is 1 set of lights that appear to be brighter than the rest and make it look like an aircraft is on the runway.  It seems like the light build is between Taxiway 'Y' and 10/28 runway.  I am not sure if it is a 'hump' in the runway; but these lights seem to be brighter than all the other centerline lights.  If you fly the 33L ILS or PAPI at night you should be able to see it. Optical illusion. Have a FAA Flight Check fly a few visual approaches to this runway at night; to see if they can see the same light pattern that I see when landing on this runway.
Air carrier First Officer reported there is a group of lights within the runway center lights at BWI airport that appear to be brighter than the others creating an optical illusion.
