I purchased projector headlamps from ebay and when I went to put in my new bulbs (PIAA Extreme White+ H7's for High and Main, H3 for Fog, and Philips Bluevision H6W for running lights) I found H7's in the highs, H3's in the mains, 5W's in the running lights. Are all projector lights like this or am I getting the shaft from a ebay seller? Can mains be strong enough with H3's. All info is appreciated!!!
