SHOULD YOU REPLACE BOTH HEADLIGHTS WHEN ONE BURNS OUT?

Written by Headlight Revolution | Apr 10, 2023 3:18:34 PM

Have you ever wondered if you should replace both headlights when only one gives up the ghost? In this helpful guide, we'll dive into the pros and cons of replacing both headlights at once. Our guide will help you make the best decision for your vehicle and driving experience.

Why Replacing Both Headlights Could Be a Bright Idea 

Here are a few compelling reasons to consider changing both headlights, even if only one has stopped shining:

Balanced Illumination

As headlights get older, their brightness fades. Changing both ensures equal lighting on both sides of the road, enhancing your nighttime visibility and reducing eye strain.

Convenience

Save time and effort by replacing both headlights together, avoiding a second replacement when the other headlight inevitably fails.

Safety First

Uneven lighting can make it hard to spot road signs, pedestrians, or obstacles. Replacing both headlights reduces this risk, keeping everyone on the road safer.

Reasons to Replace Just the Burned-Out Headlight 

There are times when replacing only the faulty headlight might make more sense:

Cost Savings

If you're on a tight budget, you can save some cash by changing only the burned-out headlight.

Different Bulb Types

Changing only one headlight may be sufficient if your low- and high-beam bulbs are different.

Recent Replacement

If you've recently changed one of your headlights, it might not be necessary to replace both when the other one burns out.

9 Illuminating Headlight Replacement Tips 

Whether you decide to replace one or both headlights, these helpful tips will make the process a breeze:

  1. Consult Your Owner's Manual: Check your vehicle's manual for specific headlight replacement instructions, including any required precautions or tools.
  2. Choose the Right Bulbs: Pick the best bulbs for your vehicle, taking into account compatibility, brightness, and color temperature.
  3. Check Wires and Connectors: Inspect wires and connectors for damage before replacing your headlights, and replace them as needed.
  4. Proper Alignment: After changing your headlights, make sure they're aligned correctly for optimal lighting without blinding other drivers.
  5. Consider Upgrading: Replacing your headlights could be the perfect opportunity to upgrade to a higher-quality bulb like LEDs or HIDs for better visibility and energy efficiency.
  6. Replace in Pairs: If only one headlight has failed, it's generally a good idea to replace both for consistent brightness and color temperature, preventing another replacement soon after.
  7. Use Gloves: Handle bulbs with gloves to avoid fingerprints, oil, or debris affecting their performance or lifespan.
  8. Clean the Lens: Clear away grime, dirt, or debris from your headlights' lenses before installing new bulbs for maximum brightness and clarity.
  9. Test the Lights: Ensure your headlights are working correctly after replacing them, including illumination and any automatic functions.

This article is not intended to imply vehicle-specific street legality. LED and HID bulbs are street legal in the USA for fog light use only and not in low beam or high beam headlights because they are not compliant with DOT / FMVSS108. When looking for on-road-use headlight upgrades, we recommend DOT-compliant headlight housings, not bulb replacements. Certain specialty vehicles strictly limited to off-street use and not having DOT registration or license plates may use these products exclusively off-streets.
