The 1139 series is High/ Lo Beam for use with matching set of 1129s for quad head light vehicles. Features a classic dome or bubbled prismatic lens to match the look of the 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. Added lead enhances glass strength. Prismatic lens provides superior photo-metric light distribution. Four time finished vacuum metalized steel reflectors improve reflection 4 to 1 next to stock. Bulb assembly protected by high-density silicone rubber boot with venting to guard against dirt and moisture.
