Well I not an expert but the one in the top of the web page (volumetrix) you can do it as follow:
1.- Create your title as you want
2.- applying the light zoom effect to the title
3.- Animate the title with as typing machine "effect" (check the last tag in the title options)
4.- Animate the ligth effect, in the X position, the first key frame and the last key frame, you will create that the ligth will be move fromn left to rigth or rigth to left, as you want.
I think now you have the big picture how to do it, practice and experiment, I sure you will do the effect as you want!.
I did not do the effect as it is in the web page, I am not a pro with BR, I just was traying to give you the big picture, you can play with it.
I think in this effect you can include the blur filter to the light, you will have other different wiew, also the light intensity in the effect is bigger that the standard in the BR ligth effect.
I this case I recomend you first get the settings of the ligth as you want, then animate the ligth and the last animate the title.
