How to Fix Fading or Broken DRLs on Your 2018-2021 Volvo XC60: Step-by-Step Replacement

TL;DR

On 2018-2021 Volvo XC60 models, the daytime running lights (DRLs) commonly fail due to heat damage and UV degradation of the light guide strip and LED board inside the headlight. Usually nothing is needed on the Volvo Xc60 - it is a direct electrical swap. A minority of cars with self-checking lamps flag a bulb-out warning that a short coding change clears.

What Goes Wrong with XC60 DRLs

The DRL system in the 2018-2021 Volvo XC60 uses a light guide strip—a clear plastic channel that distributes light from an LED board—to create the distinctive Thor's Hammer shape. Over time, the LED board can suffer from heat cycling, which degrades the solder joints and causes flickering or complete failure. Meanwhile, the light guide strip can yellow from UV exposure or develop microcracks, scattering light and making the DRL appear dim or uneven. Moisture ingress through compromised seals can also corrode the electronics, leading to intermittent operation.

Diagnosing the Problem

Start by observing the DRL behavior. If one side is noticeably dimmer or has dark spots, the light guide is likely the issue. If the DRL flickers or doesn't light at all, the LED board may be failing. Check for condensation inside the headlight housing, which indicates a seal problem. To confirm, you can swap the LED board from the working side to the faulty side—if the problem follows the board, it's the board; if it stays, it's the light guide or wiring. A simple multimeter can test for voltage at the connector, but often visual inspection is enough.

Step-by-Step Replacement

1. Safety first: Turn off the ignition and disconnect the negative battery terminal to avoid electrical shocks. 2. Access the headlight: Remove the front bumper cover or the wheel arch liner to reach the headlight mounting bolts (consult your service manual for exact procedure; typically involves removing a few screws and clips). 3. Remove the headlight: Unbolt the headlight assembly and gently pull it out, disconnecting the electrical connectors. 4. Open the housing: Remove the back cover of the headlight to access the DRL module. 5. Replace the light guide and LED board: The light guide strip and LED board are usually held by clips or screws. Carefully detach the old components and install the new ones, ensuring all connections are secure. 6. Reassemble: Reverse the removal steps, reconnect the battery, and test the DRL function. The entire process takes about 1-2 hours per side for a DIYer with basic tools.

Fitment Tips

This replacement is designed specifically for 2018-2021 Volvo XC60 models. Ensure you are purchasing the correct part for your model year, as there may be minor variations. The Volvo Xc60 takes the part without wiring work. Whether a dash warning follows depends on the car's own diagnostics rather than on the board. Before installation, inspect the headlight housing seals and replace them if worn to prevent future moisture issues. Handle the light guide strip with clean gloves to avoid fingerprints or scratches that can affect light output. After installation, check for any error messages on the dashboard; if present, recheck connections.

Fix vs Replace

Replacing the entire headlight assembly is a common alternative, but it's significantly more expensive and time-consuming. A new OEM headlight assembly from a dealer can cost well over a thousand dollars per side, while our DRL light guide strip and LED board kit is a fraction of that cost. Installation of the kit takes about 1-2 hours, whereas a full headlight swap may take longer and require bumper removal. By fixing the DRL components, you keep your original headlight housing, maintaining the factory fit and finish. For current pricing, please visit the product page.

FAQ

Straight swap on the Volvo Xc60. The only variable is whether the car's lamp diagnostics object, which a short coding session resolves.

A: On the Volvo Xc60 the connector is factory-matched and no wiring is touched. If a warning appears it comes from the car's lamp monitoring, not the part.

Q: Is this an afternoon job or a weekend one?

A: For a DIYer with basic tools, it typically takes about 1-2 hours per side.

Q: Is this part compatible with all 2018-2021 XC60 trims?

A: Yes, it is designed to fit all 2018-2021 Volvo XC60 models, but always verify your specific model year and trim.

Q: What if I see condensation in my headlight after installation?

A: Condensation may indicate a faulty seal; inspect and replace the headlight housing seals if necessary to prevent moisture ingress.

Standards reference: for the Volvo Xc60, the daytime running lamp is governed by UN ECE Regulation 148 (which superseded R87) in most markets and by FMVSS 108 in the United States - these define when the lamp runs and at what output. The parts this guide covers return the lamp to that defined behaviour.
