Daytime driving lights not working

I recently purchased a h2 and the driving lights don't come on in the day or evening.  I've changed the bulbs but still nothing.  I don't know too much about this vehicle yet and was wondering if anyone has a clue as to why they are not coming on.  Thanks !!!!!!!!!!!!!!!!

Do you have the light switch on auto?? (which is furthest to the right I believe)
 
OOOPPPS nevermind -  you said H2...don't knows nutin bout dem H2's!

My witch is always on auto..

Is it supposed to work when the switch is on auto ??   Where is the sensor on this vehicle ??  Thanks !!!

Right hand side of the upper dash, right next to the windshield to the right of the right side defroster vent, paasenger side of the interior just behind the hood, left of the righ rearview mirror...Approximately
