LED Headlight Bulbs and Subaru Daytime Running Lights: A Comprehensive Guide

If you’re a proud owner of a Subaru, you already know that daytime running lights (DRLs) are a standard feature in most Subaru models. DRLs are important because they help other drivers see you on the road, especially during low-light conditions. However, some Subaru owners may wonder if they can upgrade their DRLs with LED headlight bulbs. In this guide, we’ll answer the question: do LED headlight bulbs allow for Subaru daytime running lights?

Key Takeaways:

  • LED headlight bulbs can be used to replace stock halogen bulbs in Subaru models.
  • LED headlight bulbs offer several benefits, including increased brightness and longer lifespan.
  • Subaru DRLs can be upgraded with LED bulbs, but wiring modifications may be required to ensure proper operation.

How do LED Headlight Bulbs Work?

LED stands for "light-emitting diode." LED headlight bulbs are made up of tiny semiconductor diodes that emit light when an electrical current is passed through them. Unlike halogen bulbs, LED bulbs do not have a filament that can burn out over time.

LED headlights have several advantages over traditional halogen bulbs. LED bulbs are much brighter, which can help improve visibility on the road. They also have a longer lifespan and use less power, which can save you money on replacement bulbs and reduce your vehicle’s energy consumption.

What are Daytime Running Lights?

Daytime running lights (DRLs) are a safety feature that improve visibility during daylight hours. DRLs are typically located in the front of a vehicle and turn on automatically when the engine is started. DRLs are not as bright as headlights, but they help other drivers see your vehicle from a distance.

Most Subaru models come with factory-installed DRLs. These lights are usually located in the headlight assembly, but they can also be located in the fog light assembly or in a separate housing. The exact location and style of DRLs can vary depending on the specific Subaru model and year.

Can LED Headlight Bulbs be Used for DRLs in Subaru Vehicles?

Yes, LED headlight bulbs can be used for DRLs in Subaru vehicles. However, it’s important to note that not all LED bulbs are compatible with every Subaru model. To ensure proper operation, you should choose LED bulbs that are specifically designed for your Subaru’s make and model.

In addition to choosing the right LED bulbs, you may need to make some wiring modifications to the DRL circuit in your vehicle. This is because Subaru DRLs are designed to work with halogen bulbs, which have a different power draw than LED bulbs. If you install LED bulbs without making any modifications, your DRLs may not work properly or may not work at all.

How to Upgrade Subaru DRLs with LED Headlight Bulbs

If you’re interested in upgrading your Subaru’s DRLs with LED bulbs, here are the steps you’ll need to follow:

  1. Choose LED bulbs that are specifically designed for your Subaru model. You can consult your vehicle’s owner’s manual or contact a reputable automotive parts supplier for guidance.

  2. Remove the old halogen bulbs from your vehicle’s headlight assembly. This process will vary depending on your specific Subaru model, so consult your owner’s manual for detailed instructions.

  3. Install the new LED bulbs into the headlight assembly. Be sure to follow the manufacturer’s instructions for proper installation.

  4. Test your new DRLs to ensure they are working properly. If the DRLs are not functioning correctly, you may need to make wiring modifications to the circuit. Consult a professional automotive technician if you’re unsure how to proceed.
