You can buy LED bulbs for your car from a variety of sources, including major auto parts retailers like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, online marketplaces such as Amazon and eBay, and specialty automotive websites like CarID and AmericanMuscle. For a direct-from-manufacturer option with strong warranties, sites like Diode Dynamics and Philips Automotive Lighting are excellent choices. The best place for you depends on your need for immediate installation, specific brand preferences, or expert advice.
When choosing a retailer, consider the bulb size (like 9005 or H11 for headlights), color temperature measured in Kelvin (K) for the desired light color, and lumens, which indicate brightness. Reputable brands will provide this data clearly. For critical lights like headlights, opting for bulbs with proper SAE/DOT certification ensures they are legal for road use in the U.S. and are designed to prevent glare for other drivers.
| Retailer Type | Examples | Key Advantages | Potential Drawbacks |
|---|---|---|---|
| Local Auto Parts Stores | AutoZone, Advance Auto Parts | Immediate availability, in-store assistance | Limited high-performance brand selection |
| Online Marketplaces | Amazon, eBay | Vast selection, competitive pricing | Varying seller reliability, risk of counterfeit products |
| Specialty Automotive Sites | CarID, AmericanMuscle | Curated options, vehicle-specific fitment tools | Longer shipping times than local stores |
| Manufacturer Direct | Diode Dynamics, Philips | Highest quality assurance, strong warranties | Often higher price point |
Installation complexity varies. Interior and license plate bulbs are often simple DIY projects. For headlights and fog lights, some vehicles require bumper or headlight assembly removal, which might necessitate professional help. Always check your vehicle's owner's manual for the correct bulb sizes before purchasing.

I just grab mine from Amazon. You type in your car's year, make, and model, and it shows you bulbs that definitely fit. The reviews are everything—I look for ones with tons of photos and videos showing the actual light output. It’s cheap and shows up in two days. Just stick to well-reviewed brands, not the no-name stuff.
