Reverse bulb

Hello everyone, the problem I have is that every time I put the reverse in my Renault Kangoo 1.9 d, the lights of the march back do not light ... I think it is the bulb, but I do not know where it is to change it .... Does anyone know where it is? or I could facilitate the electrical circuit of the Kangoo 1.9 I will appreciate them forever !!!! thank you so much!!!

It is usually located on the side of the gearbox.
