This has been discussed before. The flashing warning light is to let you know that one of the DRL LED's has gone bad. Those bulbs are built in, so the entire headlight assembly has to be replaced. Note: This DOES NOT apply to the headlight bulbs as those can be replaced. If you're fairly handy with basic tools (screwdriver), you can get a used replacement headlight assembly from eBay for $350 or less.
Premium Package (SL) with power panoramic moonroof, LED headlights, Forward Emergency Braking, Blind Spot Warning and Moving Object Detection.
