LED Headlight Control Modules for DRLs (Daytime Running Lights)

 The search for affordable LED headlight control modules for daytime running lights (DRLs) has become a growing challenge for many vehicle owners. High dealership costs and compatibility issues can make replacing these modules a frustrating experience. At Pro Vision Lighting & Electrical, we’re beginning to introduce after-market solutions that deliver reliable performance without costing the earth. 

Key Considerations When Replacing Your Headlight Control Module

1.      Used Modules and Coding Issues:
We’ve noticed that when people buy used headlight control modules, they often run into coding problems. This typically happens because the used module is already coded to the original vehicle it came from. In some cases, your scan tool—or the module itself—doesn’t have the capability to clear the existing code or reset the computer, making it difficult or impossible to re-code the module for your own vehicle. 

2.      New Modules Offer a Clean Slate:
With new LED modules, 99% of the time, the vehicle’s computer readily accepts them because they start with a clean slate. In certain instances, you may still need a scan tool to reset the system. However, new modules generally have fewer compatibility issues than used ones.

3.      Matching Part Numbers and Configurations:
Sometimes the same module model number may be used across different vehicle trims or regions, each with a slightly different function. For example, a base model’s module might lack the capabilities required for upgraded features like a “laser function” or support for a different territory’s standards (EU vs. USA). Often, if the part number matches, the module is new, and the pin configuration aligns with your existing setup, it’s worth trying. Make sure you can return it if it doesn’t work out.

Finding Reliable After-Market Solutions

We are compiling a list of tried-and-tested products on our website to help you find compatible, cost-effective LED headlight control modules for DRLs. By offering these options, we aim to save our customers from paying thousands of dollars for a complete headlight assembly at the dealership.

Tips for Buying and Checking OEM HID Xenon Globes by Pro Vision Lighting.

 How to Identify What Globe Is in My Car.

If you blow a factory-fitted HID Xenon Globe, you can test it a few ways. The identity of the bulb type is on the globe’s base or side of the globe, with its main identifiers being D1S, D2S, D2R, D3S, D3R, D4S, D4R, D5S, D8S. This indicates the fitting and bulb type.

Colour temperature (e.g., 4300k, 4200k, or 6000k) tells you if it's a warm white or cool white globe. Voltage (42V or 85V) corresponds to the Ballast. D1 and D2 series are old 85V; D3, D4, D8 are newer 42V. D5S is unique with a built-in ballast, not to be confused with the ignitors on the back of D1, D3, and D8 globes. D2 and D4 might have the ignitor in the OEM Factory Fitted HID Xenon Ballast or on the headlight connector.

Manufacturers like Philips, Osram, Harrison have their own series numbers like 66340, basically telling you it’s an Osram D3S 6000k Xenstart globe.

Check via your VIN with the dealership or check out a Philips or Osram Bulb Application Guide. You will search by vehicle like this -> VW - 2016 - Amarok - low beam globe type.

Is the Globe Blown?
A burnt-looking pressure cylinder is not always an indicator that the globe is blown. When lit, HID globes burn very hot, so looking a bit burnt is not always an indicator of a faulty globe. If it’s as black as night though, this is a good indicator the globe is blown.

Globe or Ballast Faulty?
Sometimes its prudent to swap the globes around. If the fault follows the globe, it’s blown. If the fault stays on the same side it is likely to be the ballast. Some HID systems have separate ignitors, which also burn out — we advise that an automotive electrician help in diagnosing the exact problem.

How to Find a Company that Sells Good HID Globes?
With so many after-market Xenon Bulb Replacements around you want to look out for fakes or ancient stock. Dealers overcharge, some suppliers lie. Pick a local supplier with genuine reviews by google or trustpilot and see if the business has a track record of more than 12 months.

Remember, headlight relays, connectors, computer faults, wiring faults, etc. exist too. But I hope this helps make your diagnostics a bit easier.

Diagnosing a Faulty HID Globe

Before deciding to upgrade, it’s crucial to determine whether your HID globe or the ballast (headlight control module) is faulty. Follow these steps to diagnose the issue:

1. Check for Symptoms: If one of your headlights is dim or not working, it could indicate a faulty globe or ballast.
2. Swap the Globes: Remove the suspected faulty globe and swap it with the functioning one on the opposite side. If the issue moves to the other headlight, the globe is the problem. If the fault remains on the same side, the ballast is likely the culprit.
3. Inspect for Damage: Look for any visible signs of wear, such as cracks or discoloration on the globe, which might indicate it needs replacement.

Understanding the cause of the issue will help you decide whether to replace the faulty component or upgrade both globes to LED.

Why Upgrade to LED?

Switching from OEM HID Globes to LED offers a host of benefits, making it a worthwhile upgrade for your vehicle. Here are the top reasons:

1. Extended Lifespan

LED globes have a significantly longer lifespan compared to HID. This reduces the frequency and cost of replacements over time.

2. Enhanced Reliability

LEDs are engineered to provide stable performance in various conditions, ensuring reliable illumination without flickering or dimming.

3. Cost-Effective

While the initial investment in LED globes may be higher, their durability and efficiency result in long-term savings.
