The 1139 series is designed for High/Low Beam use and should be used with a matching set of 1129s for quad-headlight vehicles. It features a classic convex prismatic lens to match the look of old sealed beam headlights. Perfect for restoration, muscle cars, and hot-rods. The lead-crystal glass lens does not oxidize (become hazy or accumulate film) like plastic lenses. Additionally, added lead enhances the glass strength. The prismatic lens provides superior photometric light distribution. The four-phase vacuum metalized steel reflectors improve reflection 4 to 1 compared to stock. The bulb assembly is protected by a high-density silicone rubber boot with venting to guard against dirt and moisture. The product is DOT Compliant.
