But it starts dimming because of the loss in current, right?

Right, the current drops as the charge is stored on the capacitor.

and substituting q/C for V and qo/C for Vo where qo is the initial charge on the capacitor you get an equation of the same form q = qo e^-t/τ. Therefore the charge also decreases exponentially. By differentiating the previous equation w.r.t time (i = dq/dt) you get i = -qo/τ e^-t/τ same with the current! (- implies current decreases with time)
