LED-GTS-R\u00fcckleuchten f\u00fcr den BMW 3er G20\/G80 M3 (2019\u20132025): Umr\u00fcstung auf sequenzielle R\u00fcckleuchten<\/h1>\n

The G20 generation of the BMW 3-Series is a sharp-looking car, and the G80 M3 sharper still \u2014 but the rear light signature is one area where owners consistently want more presence. GTS-style LED tail lights are the go-to upgrade: they give the car a motorsport-inspired rear graphic, add a fluid sequential indicator sweep, and modernise the whole back end without touching bodywork.<\/p>\n

These LED GTS tail lights for the BMW 3-Series G20 and G80 M3<\/strong> are built by Xunder<\/strong> and designed as a plug-and-play replacement using the car’s original factory plugs. Here’s what they do and how they fit.<\/p>\n

Fitment: G20 and G80 M3, 2019\u20132025<\/h2>\n

This set is engineered specifically for the current-generation 3-Series and its M3 flagship:<\/p>\n\n\n\n\n\n\n

If your car falls within that window, the lights are designed to be a direct fit.<\/p>\n

GTS Styling with a Sequential Sweep<\/h2>\n

The “GTS” name refers to the motorsport-inspired light graphic that gives these lamps their distinctive look. Every position runs on high-performance LEDs<\/strong>, and the turn signals are sequential<\/strong>, sweeping smoothly across the lens in a flowing motion rather than blinking as a single unit. It’s the effect that most clearly separates an upgraded car from a factory-standard one at a glance.<\/p>\n

Die black lens<\/strong> finish sharpens the look further, giving the rear a darker, more aggressive appearance that suits both the standard 3-Series and the M3.<\/p>\n

Output and Electrical Specs<\/h2>\n

The lights produce 3400 lumens<\/strong> on a 35W<\/strong> draw at 12V<\/strong>, giving strong, even output across brake, running, reverse, and indicator functions without stressing the electrical system.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Built to Last<\/h2>\n

The housing is moulded from impact-resistant ABS<\/strong>, and the lens is polycarbonate (PC)<\/strong> \u2014 a tough, shatter-resistant material well suited to the knocks and stone chips of everyday driving. The whole assembly is rated IP67 waterproof<\/strong>, sealing out rain, spray, and dust.<\/p>\n

Certification is comprehensive: CE, DOT, SAE, E-MARK and ECE<\/strong>, covering the major standards for road use across markets. A 24-month warranty<\/strong> backs the set.<\/p>\n

Plug and Play \u2014 Factory Plugs, No Cutting<\/h2>\n

These lights use the original factory plugs and harnesses<\/strong>, so installation requires no drilling and no cutting<\/strong>. You unplug the factory lamps and connect the new units directly. The package is complete: driver-side and passenger-side units plus the required harness<\/strong>, so there are no extra parts to source.<\/p>\n

As with any full LED sequential assembly, professional installation is recommended<\/strong>. On modern BMWs the lighting is monitored by the car’s electronics, so a specialist will confirm that every function registers correctly and that no error appears on the dash, as well as ensuring the units are seated and sealed properly.<\/p>\n

Why This Upgrade Works So Well on the G20<\/h2>\n
