PIAA Stratos Blue HB3 / HB4 Car Replacement Headlight Bulbs (Twin)


PIAA Stratos Blue HB3 / HB4 (Twin)

PIAA’s Stratos Blue range finally provides a reliable halogen bulb capable of achieving a strong white-blue light.

Why buy the PIAA Stratos Blue HB3 / HB4 (Twin)?

The Stratos Blue range is the culmination of PIAA’s tireless efforts to produce a halogen bulb capable of projecting an intense white-blue light beam with a blue tint, closely matching the style of xenon HIDs. PIAA has exercised the whole of its expertise and world-renowned Japanese design and engineering standards in accomplishing the Stratos Blue range – and has redefined the boundaries of halogen technology in the process.

Unlike many inferior halogen bulbs that promise a xenon-style, intense white-blue light, the PIAA Stratos Blue utilises an outstanding 6000K colour temperature in a robust, yet intricately designed package to give you a stylish white-blue light without sacrificing reliability or vision. PIAA’s superlative precision engineering ensures an accurate projection of light from the Stratos Blue, minimising the risk of dazzling others while maximising the visibility of your surroundings, so you can experience true style and safety together at last.

PIAA Stratos Blue just became the automotive industry’s new authority in xenon-style halogen lighting. Buy now at PowerBulbs, and see for yourself.

(NOTE: The special 'HB' fitting of these bulbs allows for them to be used in either HB3 or HB4 applications. Purchase includes only one twin pack of bulbs with a multi-fitting base.)
