Decided to change my reverse lights to LED. Got under the car and realized the previous owner had them unplugged. Put led bulbs I and plugged in. No reverse lights and ‘bulb out warning” on dash. Removed led’s and plugged in stock bulbs - same result. Unplug harness and no light on dash. Did notice when I plug harness in I hear a faint beep for both sides. Where do I begin?

 

Are you talking about a SC300/400 or some different vehicle? I'm not sure how or why you would go under the car to determine the reverse lights were disconnected, as they run through the trunk...

 

Sorry, posted in the wrong place. It is an sc430
