Valeo Lighting - Headlamp Condensation - Is it a Problem?

Condensation in headlights is common, but is it a safety problem?

How Serious Is Headlight Condensation?

Discover What You Need to Know In Our Webinar

Does condensation mean a headlamp needs replacing? The answer depends on factors like how long condensation in headlamps persists and how much it affects visibility? In this 10-minute free webinar, you will learn everything you need to know about headlight condensation and how to remedy the problem.

Why Does Condensation Accumulate in Headlamps?

Since headlamps evolved from sealed-beam to aerodynamic plastic units, condensation in headlights has become more prevalent. Depending on the weather conditions and your vehicle’s headlamp design, some condensation is expected. Learn what causes this issue and what kinds of condensation are a reason for alarm. Discover the difference between normal condensation and a larger problem requiring intervention or parts replacement.

What to Check During Your Inspection

Modern headlamps have ventilation systems that let air into the unit, sometimes causing condensation. But if certain parts are damaged, the problem can surpass normal condensation and affect visibility and safety. Learn which parts to pay attention to during your inspection to determine whether the headlamp is damaged or operating normally. We’ll tell you how long condensation inside headlights typically takes to dissipate. You’ll also discover why some headlights attract water - one part in particular can make it physically irresistible for water to come in if improperly sealed.

How Condensation Affects Visibility

Headlamps are vital safety equipment on your vehicle, especially for visibility in dark conditions. If you have water sloshing around in your headlamps, does it affect your visibility enough to impact safety? We’ll answer questions like this and explain how long condensation in LED headlights takes to dissipate and how that differs from halogen and xenon headlamp technologies. You’ll discover the clever ways that headlamp designers have tried to reduce the condensation issue.

How to Troubleshoot a Foggy Headlamp

Before you attempt a costly replacement of the entire headlamp unit, we’ll tell you which parts to consider replacing first to see if the problem is resolved. You’ll also discover one surprising tool you could use for a condensation in headlight fix. These tips could save your customers expensive repairs and give them peace of mind.

Valeo’s Range of Headlamps

Valeo offers a full range of headlamp bulbs and headlamp-related technologies. We not only produce headlamp assemblies for OEMs, but we also produce the replacement bulbs for consumers. Valeo Brands like Cibié have more than 80 years of experience in vehicle lighting, further highlighting our expertise in headlamp technology.

If you're wondering how these different lighting technologies work, we’ve included a handbook in our downloadable materials explaining the different lighting technology types like halogen, xenon, and LED lighting. You’ll also discover matrix beams, pixel lighting, and laser lighting systems. The handbook demonstrates the differences between different Valeo bulbs, so you can easily find the best fit for your customer’s needs.

What You Will Learn in Our Webinar

In this webinar, you will learn:

  • How to use the calibration rig on an actuator
  • What formula to use for correct actuator calibration
  • What measurements to use for correct actuator calibration

Afterwards, you can download materials like technical service bulletins on Valeo Dual Dry Clutches, including tooling requirements and actuator calibration. You may want to print out the actuator calibration bulletin for reference when performing the calibration.
