Prevents blinding on-coming vehicles: these light bulbs utilize the super high quality and most modern technology LED chips. This technology helps you get a LED array similar to the filament inside of an original halogen bulb. This creates a nice cut line on top of the beam. No pain in replacing bulbs often: a maximum level of heat dissipation is achieved when they are in use thanks to the ball-bearing cooling fan, the copper thermal heat sink, and the high-density aluminum body, ensuring up to 50,000 hrs lifespan.
