Its amazing how many people ask this question. No the Inners are not your main beam. If you ever get a chance to look at your bulbs in your larger lights you will see that they have 2 filaments. 1 is for dipped beam and the other for main beam. The inners are there simply to help out your existing larger lamps.
If you dont belive me then unplug your inners and stand infront watching while somebody puts main beam on! Prepare to see stars!

Oh and if your wondering where the sidelights work from, its a completely seperate small bulb.
