These LED Bulbs from Diode Dynamics are a direct replacement for your factory bulbs.  Diode Dynamics does not make a claim for increased light out put and are only intended to offer a more modern look for your vehicle. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. As many companies only offer guesses at light output the color match may not be exact. Diode Dynamics LEDs are built with constant-current inductive circuitry, along with transient suppression, which allows them to live for year with no flickering or failure. Bulbs are sold as a pair.
