It is characterized by a small bulb filled with halogen gas, which provides higher light output and a longer lifespan compared to standard incandescent bulbs. With a power of typically 55 watts, this lamp reliably offers visibility during nighttime driving. The H1 fitting allows for easy installation in various car models. Note that these lamps generate heat and should be handled with care to ensure their effectiveness and safety.
