Pair of DDM Tuning Bi Xenon Retrofit Mini H1 Projectors V3 Premium,2.5in,W / Mini GG Shrouds, Beam Pattern: Perfect light distribution will give plenty of light on the road in front of you while maximizing the output down the road. Incredibly sharp cutoff. Construction: Lens: Optically clear Grade A glass. Only the best lens is used for these projectors. Lens Holder: Make of a high temp nylon / fiber glass composite to withstand up to 220 celsius (438 F). Solenoid: We use a large (strong) magnetic solenoid that will pull the high beam shutter all the way to allow more light output when on high beams. With the larger solenoid we designed a deeper high beam that will illuminate further down the road. Reflector Bowl: After casting the mold each reflector is polished smooth to remove any imperfections then coated with a high temp chrome coating that is again polished to a mirror finish to reflect more light forward. The chrome coating can withstand the heat from both 35W and 55W HID systems without burning or yellowing over time. Mounting: H7 and H4 plates are included at no charge to allow for easier installation. Our threaded collar is 15mm long to limit modification needed to stock headlights during installation. Comes with rubber gaskets to properly seal the projector in place. Warranty: All DDM Projectors come with a lifetime warranty. Kit includes: 2 x H1 V3 Projectors, 2 x Mini GG Shrouds, Mounting Hardware (H7, H4 plates), Gaskets, Width: 101mm, Height: 78.6mm, Length: 136mm
