<div> <h1>DRL Lamp Tube for MERCEDES-BENZ GLE W166 (2015-2019) Long Strip Fits Left &amp; Right</h1> <p>A like-for-like replacement for the headlight's daytime running light guide — the moulded acrylic strip that distributes LED light along the daytime signature. Sustained heat inside the lamp eventually clouds, discolours or cracks the original, and the line reads dim or interrupted. Fitting a fresh guide recovers the factory look without buying a complete headlight. This is the longer guide in the assembly.</p> <p><strong>Features</strong></p> <ul> <li>Heat-resistant optical acrylic moulded to the original shape</li> <li>Factory dimensions throughout, so nothing needs trimming or adapting</li> <li>Clean, uniform light spread true to the original daytime signature</li> </ul> <p><strong>Fitment &amp; Care</strong></p> <p>Replacement calls for opening the headlight, changing the guide and resealing the unit, so a qualified technician is recommended. The original LED and wiring are reused and no coding is involved. <strong>This guide is common to the left and right headlight</strong> — order two for the pair.</p> </div>
