After-Sales Challenges in Automotive Parts: How to Quickly Resolve Headlight Issues

Modern vehicles are increasingly fitted with LED headlights, projector headlamps, and advanced lighting assemblies. While these upgrades improve safety and performance, many drivers and workshops encounter after-sales challenges such as:

Wrong headlight bulb type installed

Poor beam alignment or improper fitment

Flickering lights or CANBUS system errors

Difficulty in replacing headlight assemblies

At Conpexgroup.com,we provide globally compatible automotive lighting solutions and dedicated after-sales support to help you solve these problems quickly, no matter where your vehicle is located — Europe, Americas, Middle East, Asia, Africa, or Oceania.

1. Common After-Sales Headlight Issues

Understanding common problems is the first step toward fast resolution:

Incorrect Bulb Installation: Using the wrong H11, H7, 9005, or 9006 bulbs can cause poor light performance.

Flickering or Dashboard Errors: Modern cars require a CANBUS driver or decoder; without it, even compatible bulbs can fail.

Assembly Fitment Issues: OEM or aftermarket assemblies may not align perfectly.

Environmental Damage: Water or dust entering housings reduces LED lifespan.

2. Quick Solutions for LED Headlight Issues

A. Use the Correct Driver/Decoder

Most Conpex LED bulbs require a CANBUS driver or LED decoder:

Ensures stable electrical flow and prevents flickering.

Eliminates dashboard errors caused by vehicle detection systems.

Not installing the driver may result in voltage misreadings or damage.

B. Verify Bulb Type and Socket

Check your bulb type (H11, H7, 9005, 9006).

Match voltage and connector for proper fitment.

Plugging in without verifying may damage electronics.

Confirm mounting points and harness connector alignment.

Adjust beams according to your regional standards (DOT, ECE, JIS).

Replace damaged seals or cracked housings promptly.

3. Installation Guidance and After-Sales Support

Always disconnect the battery before replacing headlights.
