Everything else has been already checked like I answered in previous post, Now I think I am quite sure that issue is somewhere related to electricals because today, on bumps the light automatically turned off, however, while running on the smooth road surface, it turns on again. Could it be related to some damaged wires etc?

Try shaking it a little or pulling it a little & see whether the handbrake light goes off. Its either a loose connection/wire cut somewhere,mostly under the dash board.
