The Night-Tech line of bulbs from PIAA feature 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 bulbs.If you don't know your vehicle's bulb type: Find it Now
