Car LED Lights

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brake lights, LED light bulbs for cars offer brighter output, faster response time, and greater energy efficiency than outdated halogens.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 sizes 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.

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 every purchase is backed by our fitment guarantee, so you get the right LED car lights the first time.

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 halogen and LED car bulbs?

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?

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 CANbus 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.
