Laxman Singh Bisht(Salman) is nicknamed tube light by his neighbours because he is feeble-minded. Despite being special, Laxman lives by one life-lesson; keep the faith alive and you can do almost anything, even stop a war.At the outset, one must warn people that Tubelight is a departure from your regular Salman Khan mass entertainer. Here Bollywood’s darling-star plays a child-man who doesn’t take off his shirt or flex his biceps. So the audience going in for this one should invest belief in this age of innocence offering from Kabir Khan, whose past outings Ek Tha Tiger and Bajrangi Bhaijaan were more commercially-wired.
