<div> <h1>Right DRL Lamp Tube for MERCEDES-BENZ GLS X167 (2020-2024) Long Version</h1> <p>An OEM-grade DRL light tube that restores the headlight's daytime running line — the moulded acrylic guide that spreads the LED light evenly across the lamp face. Years of in-lamp heat leave the original hazed, discoloured or fractured and the daytime line looks broken up. Replacing just the guide recovers the original finish at a fraction of the price of a new headlight.</p> <p><strong>Features</strong></p> <ul> <li>Optical-grade acrylic rated for sustained temperatures inside a sealed lamp</li> <li>Moulded to the factory profile for an exact, drop-in fit</li> <li>Uniform light transmission true to the original daytime signature</li> </ul> <p><strong>Fitment &amp; Care</strong></p> <p>The headlight has to be opened, the lens separated and the unit resealed to change the guide, so installation by a qualified technician is advised. The existing LED is reused and nothing needs rewiring or coding. <strong>This is the right-side guide only</strong> — the left headlight takes a different part, so order the matching left-side item if you need a pair. Only routine lens cleaning is required afterwards.</p> </div>
