What are 7443/7440 LED Bulbs, and Where Do They Go?

7443 and 7440 LED bulbs are popular choices for automotive lighting that are compatible with a lot of different vehicles, including popular models from Toyota, Honda, Chevrolet and Nissan. They're commonly used for daytime running lights, parking lights, turn signals, brake lights, and reverse lights. These bulbs are known for their superior brightness, energy efficiency, and long-lasting durability compared to traditional halogen bulbs.


Difference Between 7440 vs 7443 Bulbs

  • 7440 LED bulbs are single-intensity, typically used for one function at the rear of your vehicle, like turn signal lights or reverse lights. They emit a consistent brightness level suitable for signalling or illumination.
  • 7443 LED bulbs are dual filaments, perfect for applications needing two brightness levels at the front of your car or truck, like tail lights that also serve as brake lights. They switch seamlessly between dim and bright modes, ensuring optimal visibility.

These bulbs are engineered to fit standard sockets, making them an easy plug-and-play upgrade for most vehicle makes and models.

Benefits of 7443/7440 LED Bulbs

  • Better Visibility & Safety

    7443/7440 LED bulbs produce brighter and more focused light, making your vehicle's signals highly visible to other drivers. More consistent illumination will always improve road safety, especially in harsh weather conditions or during nighttime driving.

  • Easy Installation

    These bulbs are designed for straightforward plug-and-play installation and fit standard sockets without requiring additional wiring or modifications, making it a hassle-free upgrade.

  • Energy Efficiency

    With advanced LED technology, these bulbs consume less power than halogen or incandescent bulbs, while also delivering a brighter output. This efficient energy use reduces the strain on your vehicle’s electrical system and extends the battery life.

  • Cost-Effective Investment

    While the upfront cost might be higher than halogens, the extended lifespan and reduced energy consumption make 7443/7440 LED bulbs a much more cost-effective choice over time.

  • Long Lifespan & Durability

    7443 and 7440 LEDs are built to last, often outliving traditional halogen bulbs by up to 50,000 hours. Their design and efficient heat dissipation assures consistent performance over the long term.

  • Modern Aesthetics

    Upgrade your vehicle’s appearance with the clean, crisp light. Bright and focused beams provide a contemporary look, boosting the overall style of your car or truck.
