H4 LED Bulb, 6500K White for Car 12V-24V Hi/Lo Beam Conversion Headlight Bulb Kit. (2pcs) f74 [CREE Chip] H4 LEDs are made with CREE chips which do not fade over time. Each bulb comes with 4 sets of beads, and the double light output design is more perfect than the cut line of halogen lamps, emitting a perfectly clear beam of light without glare, giving you an extremely wide and clear view for driving. easy in the dark or on rough roads. [Standard Socket] Designed 1:1 according to the original H4 bulb, it has better cutting line for high beam and low beam. crossing and works perfectly. The bulb produces a cool white light of 6500K, which is over 300% brighter than halogen lamps. Plug and play, no modification required, just unplug the old bulb, plug in the H4 LED bulb and start using it immediately. [Wide voltage] The H4 LED bulb has a wide voltage of 9V-32V DC, suitable for upgrading 12V-24V car headlights. LED H4 can start immediately and reach full brightness instantly, regardless of strong current and voltage. Built-in smart chip for reverse plug protection, overcharge protection and overheat protection, giving it a lifespan of over 30,000 hours. [Material of quality] The housing of the H4 LED is made of 6063 aviation aluminum alloy, and the bottom of the bulb is designed with heat dissipation fins to cool the bulb quickly. With its integrated design, it has a shockproof function, which greatly improves safety and shock resistance. With IP65 waterproof certification, it can be used in rainy days or harsh environments. 1:1 design same as halogen bulbs. The H4 LED has almost the same 1:1 dimensions as the halogen bulb, compact one-piece design, no additional decoder, fits most factory dust covers, simple plug and play, installation usually only takes 5 minutes. High-quality CREE lamp beads Using high-quality CREE beads makes the bulb more stable brightness, and through the internal voltage control chip, the brightness is stable and flicker-free, no flickering caused by power surges or low voltages. Standard Socket Standard H4 bulb socket is compatible with all car models equipped with H4 bulbs and requires no additional wires or accessories, making it truly plug-and-play and non-destructive, making installation and replacement easy. Fanless cooling construction Excellent 6063 aircraft aluminum and heat dissipation surface design make the bulb work stably. The finned cooling structure provides efficient passive heat dissipation without high temperature damage, allowing the bulb to withstand extreme temperatures ranging from -30C to and80C. A clear range of light H4 LED bulbs have a clear beam and a longer lighting distance. Emits 3 times more light than halogen lamps, no shadows, no scattering, no dark spots.
