I have a halo projector headlights I bought them three months ago. And now, the low beam from the passenger side went off as the two led on the driver side. They are the halogen bulbs that came with the kit but I don't know which one is the right kind of bulb to buy and how to install it. I looked for it and in a thread I read that it uses H1 but I'm not sure. Any help would be very much appreciated. Oh what are the most long lasting drl's because I can't turn them off.
