The Land Rover Defender has been in continuous production since 1983, evolving through several distinct generations and body styles. Modern variants are more likely to feature tinted glass and integrated electrical elements than earlier models.
From the mid-2010s onwards, newer Defenders increasingly incorporate integrated features such as brake-light patterns in the rear window and solar-control glass on certain trims. Some models also carry antenna elements built into the rear glass itself, which must be correctly reconnected during replacement to preserve radio functionality.
While most Defenders don't require ADAS calibration for rear-window replacement, matching your factory specification — including any integrated electrical or tinting details — is essential for a seamless fit and proper function.
