The interference with the headlamp housing caused byother than koito brand lamp bulbs does not comply with FMVSS 108, "lamps, reflective devices, and associated equipment."
Toyota dealers will provide a new koito brand bulb with no charge if a non-koito brand bulb is now installed, or should a headlamp bulb burn out in the future. "caution labels" will also be placed on each headlamp housing.
