Built with a copper base, full-aluminum body and intelligent drivers, they aim to reproduce a halogen-style beam while pumping out much more light. The set includes two bulbs designed for quick installation and long service life under varied weather conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow much brighter are these compared to stock halogen bulbs?\u003c\/h3\u003e\n\u003cp\u003eOXILAM rates these H4 LEDs at roughly 700% more brightness versus typical halogen H4 lamps, using a dense array of CSP chips to reach a very high lumen output and a crisp 6500K white color. That increased light helps you see road details earlier without changing the beam shape.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e32 advanced CSP LED chips per bulb for elevated luminous output.\u003c\/li\u003e\n  \u003cli\u003e6500K color temperature for daylight-white illumination.\u003c\/li\u003e\n  \u003cli\u003eEngineered to intensify road illumination while maintaining beam clarity.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these bulbs fit my car and trigger warning lights?\u003c\/h3\u003e\n\u003cp\u003eThese H4 9003 bulbs are designed in a 1:1 form factor to match halogen sockets and use intelligent IC drivers to minimize CANBUS errors on most vehicles.
