ossie cossie

hello i would like some info. i would like to upgrade my headlight globes in the main beam on my escos to a 100watt dip and 130watt main beam. also like to put 100 watt globes in the other main beam lamps. i have noticed that the larger part of the headlight only has dipped wires and the main beam is on the smaller part of the headlight. also with the ignition on and the lights turned to side lights the dipped beam comes on about half brightness is this rite or not? when i turn the ignition off only the side lights are on. is this the same for all escos,s or is it a daytime run thing. thanks all.
