Brite Box for Toyota 4Runner 2003+

The Brite Box for Toyota 4Runner is a self-contained device that greatly contributes to driving safety on dark roads by improving both the output and coverage of standard vehicle headlights. All vehicles have two distinct beam patterns: low beam for close range illumination, and high beam for long range illumination. Im most vehicles, when the high beams are activated low beams shut off. The resulting choice of "near" vs "far" illumination compromises safety and comfort because at maximum, only 54% of the vehicles lighting potential is being used at any given time. Installing brighter headlight bulbs does little to help because the coverage of the headlights is still compromised. Additionally, if your vehicle has factory fog lights, they too shut off when high beams are engaged. How does one solve the problem?

Enter the Brite Box. Brite Box illuminates the low beams (and fog lights with Fog Light Control models) when the high beams are activated which allows 100% of the lighting potential of the vehicle to be utilized. Brite Box provides an even carpet of light that stretches from near to far. Safety and comfort are improved because the driver can now see a larger portion of the road. The safety benefits and circuitry of Brite Box has been proven in millions of miles of over the road testing, and is used by law enforcement and transportation companies. Brite Box features easy plug in installtion (in most vehicles) and can usually be installed in 30 minutes or less.
