We consider self‐consistent coupling of the recently introduced new class of Weyl‐conformally invariant lightlike branes ( WILL ‐branes) to D = 4 Einstein‐Maxwell system plus a D = 4 three‐index antisymmetric tensor gauge field. We find static spherically‐symmetric solutions where the space‐time consists of two regions with different black‐hole‐type geometries and different values for a dynamically generated cosmological constant, separated by the WILL ‐brane which “straddles” their common event horizon. Furthermore, the WILL ‐brane produces a potential “well” around itself acting as a trap for test particles falling towards the horizon.
