Upgrade your headlights with this 4-piece LED bulb kit. It includes both H11 and 9005 sizes, so you can replace your low beams and high beams at the same time. The bulbs emit a cool white 6000K light (they call it 10000K but it's likely around 6000K), which is brighter and whiter than stock halogens. They're super bright with 3570 CSP LED chips, fanless design (so quiet), and are plug-and-play—no wiring mods needed. Voltage range is 9V-36V, so they work with most cars. Made from aviation aluminum for heat dissipation, and they come with a 5-year warranty. Just make sure your vehicle uses H11 for low beam and 9005 for high beam (common in many trucks and SUVs). Easy install, huge visibility improvement for night driving.
