Replacement Halogen Headlight Bulbs H4 for Wranglers with converted headlight housings.

The Night-Tech line of high output replacement bulbs from PIAA features several advancements in performance, durability, and manufacturing. Through the use of a unique mix of gasses including a higher proportion of inert gasses as well as a new filament material these bulbs offer up to 90% more light than a conventional bulb with a greater life span. The gasses, filament material, and coatings on the bulbs offer a color temperature in the 3600 Kelvin range for a whiter output than standard bulbs and retain a DOT/SAE approval. The unique dual band bulb coatings not only create a whiter light but a brighter, longer range (up to 35 meters) output when compared to other replacement bulbs.
