Upgrading to the 2021 Toyota 4runner Limited model brought with it the anticipation of enhanced visibility, thanks to its factory-installed LED headlights. Trading in a 2019 Limited for the newer model, the promise of stock LED unified low/high beam projectors and LED reflector fog lights was a key highlight. This review assesses the performance of these new LED headlights, comparing them to previous models and aftermarket alternatives. While the daytime running lights (DRL) remain halogen, the focus is on the significant change in low and high beam technology.
LED Low Beams: A Significant Improvement in Visibility
The LED low beams in the 2021 4Runner Limited are a notable advancement. Finally achieving a level of brightness comparable to contemporary LED setups, such as those found in the Toyota Corolla, these low beams offer a substantial improvement over previous halogen options. The light spread is impressively wide and extends far down the road, providing excellent nighttime visibility. Crucially, the light maintains good contrast, avoiding the overly blue hue that can reduce visibility in some LED bulbs. This enhancement marks a significant step forward for 4Runner nighttime driving safety and clarity.
LED Fog Lights: Functional and Redesigned
The LED reflector fog lights represent a design departure from the “high-performance” OEM LED fog lights of prior 4Runner models. Functionally adequate, these new fog lights do not project as wide a beam as their predecessors and lack the black bezel aesthetic that many found appealing. Their contribution to overall visibility is somewhat diminished by the already wide and effective LED low beams, making their impact less pronounced in typical driving conditions.
LED High Beams: A Minor Setback in Performance
Conversely, the LED high beams in the 2021 4Runner appear to be less effective than the halogen 9005 high beams they replace. Observations suggest a reduction in throw distance, intensity, and overall contrast. Furthermore, the automatic high beam assist feature is reported to be unreliable and potentially disruptive to other drivers. While high beam usage is typically less frequent, this aspect of the LED headlight system represents a slight decrease in performance compared to the previous halogen setup.
In summary, the 2021 Toyota 4Runner Limited’s LED headlights are a worthwhile upgrade, primarily due to the vastly improved LED low beams that bring its nighttime driving illumination to modern standards.
