Elite Vision Advanced Automotive Accessories Elite LED Bulbs are made to be as simple as swapping out a halogen bulb! They were made to be about the same size as your stock halogen bulbs, so there will never be a fitment issue with your EV LED bulbs! Copper Frame: our LED bulbs were made with a copper frame to give the LED a longer lifespan because of how much cooler it will run because of better heat dissipation. EV’s LED bulbs are made to give off a proper 360 degree beam pattern. CanBus Functionality: Some newer cars are equipped with CanBus systems, therefore the LED will need a canbus chip, which were engineered inside the LED bulbs to work on those vehicles to prevent flickering of the LED bulbs.
