PIAA fitted but do nothing
 

hi all have just brought my new impreza and have piaa fitted but when press the switch inside nothing happens where can i get wiring diagrams and also any basic advice as have had nothing to do with these in the past thanks

Just try your high beam first you might find that they are driving lamps,and have been wired up to the main beam,not the fog light switch in the car. If still no joy try the bulbs. If that fails follow your wiring back into the car to see where it is connected too.

What he said: they are now driving lights, NOT fogs, and should come on with main beam and off with the dip beam. The switch may, or may not, do anything. Mine still allows me to CHOOSE if they come on with main beam, so they don't get flashed around town, etc
