Restore the iconic halo-style daytime running lights on your Defender L663 with the DA5319 Headlight Signature DRL LED Repair Module. When the factory LED strip fails, this module brings back the bright, crisp DRL signature your Defender is known for. Designed as a direct-fit aftermarket replacement, it powers the headlight’s main halo signature ring, solving common DRL failure without replacing the entire headlamp unit.

Each module includes thermal grease, which must be applied between the LED unit and the heat sink to ensure proper cooling and long service life. Installation requires opening the headlamp housing but uses factory mounting positions once inside.

Fits:

• Land Rover Defender L663 (All Engines & Trims)

• Works on either LH or RH headlight

Includes:

• 1 × DRL LED Repair Module

• Thermal grease packet

Install tip: Apply thermal grease generously and evenly. Ensure all seals are properly reseated to prevent condensation inside the headlamp.
