Automotive LED Light Bulbs for Every Vehicle

Car LED lights are one of the easiest and most impactful upgrades you can make to your vehicle. Whether you’re replacing interior dome lights or upgrading your headlights and brake lights, LED light bulbs for cars offer brighter output, faster response time, and greater energy efficiency than outdated halogens.

At Underground Lighting, we carry a wide selection of automotive LEDs compatible with most makes and models of cars and trucks. From switchback turn signals and taillights to LED fog lights and LED interior accent lights, our bulbs are designed for simple plug-and-play installation using your factory housings - no rewiring or custom tools required.

These LEDs come in various fitments and color temperatures, so you can customize your lighting setup just how you want it. Whether you drive a compact car, SUV, or heavy-duty truck off-road, our collection of LED lights for cars delivers both form and function in one upgrade.

Upgrade Your Driving Experience with LED Lights

  • Simple Installation

    Our automotive LED lights are designed to fit standard sockets and housings. Our replacement bulbs require no special tools or modifications, making them a great DIY-friendly upgrade

  • Fast Response Time

    LEDs illuminate instantly - no warm-up time. This is especially important for brake lights and turn signals, where quicker activation improves reaction time for other drivers.

  • Lower Power Consumption

    Because LEDs require less power, they reduce the strain on the lighting and electrical system. That means more efficient energy use and less draw from your battery and alternator.

  • Long-Lasting Performance

    LED bulbs can last up to 20,000-50,000 hours, depending on application and usage. That’s significantly longer than halogens, meaning fewer replacements and more peace of mind.

  • Sleek, Modern Aesthetic

    Car LED lights offer a crisp white or cool blue tone that instantly updates the look of your vehicle. Say goodbye to dull, yellow halogens and hello to super bright car lighting - LEDs bring your car into the modern age with a premium feel.

  • Enhanced Visibility and Safety

    LED light kits produce a brighter, more focused beam pattern, which means you’ll see more of the road and be seen more clearly by other drivers - especially in poor weather conditions or at night.

How to Choose the Right LED Lights for Your Car

Choosing the right LED light bulbs for cars can be easy when you follow a few simple steps:

  1. Identify the bulb type you need: You can find this in your owner’s manual under the "light specifications" section or by removing the existing bulb and checking the part number. Common types include 3157, 7443, and 1157 for exterior lights or festoon and wedge bases for interior bulbs.
  2. Use our Vehicle Search Tool: Match the exact bulb sizes for your make, model, and year to guarantee compatibility and eliminate guesswork.
  3. Decide on the features that matter most to you: Brightness level, color temperature, or CANbus compatibility for modern vehicles with error-checking systems. Our team is always available to help you compare options and find the best match.
  4. Place your order with confidence: We offer fast, reliable shipping across the U.S. and internationally, and every purchase is backed by our fitment guarantee, so you get the right LED car lights the first time.

Frequently Asked Questions: Car LED Lights

Can I install LED lights in my car myself?

Most LED bulbs are plug-and-play, designed to fit your factory housings with no extra tools or modifications. Just remove the old one, insert the new LED, and test it. If you experience flickering or dashboard errors, you might need a load resistor or decoder.

What’s the difference between a halogen bulb and LED bulb?

Halogen bulbs generate light using heat, which is less efficient and causes them to burn out faster. LED bulbs produce light electronically, resulting in lower power consumption, brighter output, cooler operation, and significantly longer lifespan.

Do LED bulbs work for all parts of the car?

At Underground Lighting, we have automotive lighting that works across all applications - headlights, taillights, brake lights, fog lights, license plate lights, dome and map lights, trunk lights, and more. Just make sure to get the correct bulb size and type for each area.

Will LED bulbs fit my car?

Our automotive LED lights are compatible with a wide range of vehicles, and you can use our Vehicle Finder to quickly check what fits your specific make and model. If you’re unsure, our lighting experts are here to help.

Why do some LED bulbs need resistors or decoders?

Some vehicles, especially newer ones, have advanced systems that monitor bulb performance. When switching to LEDs, the lower power draw can trigger “bulb out” warnings or cause hyper-flashing. Load resistors or CAN bus decoders fix these issues for smooth operation.

Can LED lights drain my car battery?

LED lights are actually more energy-efficient than traditional halogen bulbs, so they draw significantly less power from your vehicle’s electrical system. That said, like any electrical accessory, if LEDs are left on for an extended period while the engine is off, especially interior or accent lights, they can slowly drain the battery over time. To avoid this, make sure all lights are turned off when the vehicle is not running. For most drivers, LED bulbs are a smart upgrade that helps conserve battery power, not drain it.

Can I mix LED bulbs with a light kit in my car?

Yes. You can pair individual LED bulbs with a light kit as long as everything matches your vehicle’s power and connection type. Most drivers do this when they want stronger brightness in one area and a fuller lighting upgrade in another.

Will LED bulbs work properly in reflector headlights?

Yes. LED bulbs can work in reflector headlights, but results vary by design. Some reflector units spread the light evenly, while others create glare or uneven patterns. Choosing LED bulbs made specifically for reflector headlights gives you a much cleaner beam pattern and keeps oncoming drivers comfortable.
