RECON Projector Headlights are sold as a set & use H1 Style headlight bulbs for both Low-beam and High-beam. RECON projector headlights come with 4 standard halogen bulbs already installed; however, if you wish to upgrade to XENON Headlight Bulbs, you must order QTY 1 of either part # 264H1DW, 264H1PB, or 264H1SY.
However, if you want to upgrade to full HID's in your projector low-beam, you must order QTY 1 of part # 264H1HID. Keep in mind there are two bulbs in each projector headlight, so you will need to buy two sets of headlight bulbs for each set of projector headlights you are upgrading the bulbs in. Our recommendation is to use HID's in your low beam projector and use Xenon gas filled bulbs for your high beam.
