DELTA CLASSIC 5-3/4″ Hi/Lo HALOGEN HEADLIGHT KIT PART# 01-1139-50

 Classic 5¾” Universal Hi/Lo Halogen Headlight Kit – 1139 Series — MADE IN THE USA

The DELTA 1139 Series Classic 5¾” Universal Hi/Lo Halogen Headlight Kit is designed for high- and low-beam applications. For vehicles equipped with quad headlights, it should be paired with a matching set of 1129 Series headlights.

Featuring a classic convex, prismatic crystal glass lens, this headlight delivers the timeless appearance of traditional sealed-beam headlights while providing superior light distribution. Ideal for classic car restorations, muscle cars, and hot rods, the glass lens resists oxidation, haziness, and film buildup commonly associated with plastic lenses.

The four-phase, vacuum-metalized steel reflectors provide up to four times the reflectivity of stock reflectors, helping improve light reflection. A high-density silicone rubber boot with integrated venting protects the bulb assembly from dirt and moisture.

This headlight kit is DOT compliant and designed to replace standard 5¾” headlights using H5006, H4, or 9003-type connections.
