Why is there a warning light flashing when you push on the brake pedal its a orange light and looks like a oil filter with five lines on the inside of it?

If you have led lights when the brake light warning switch is closed (foot on brake) because it has a predetermined voltage and the rig is change to led's there is a different voltage used, hence an error warning light. can get around it by adding the original lamp in series with the brake circuit out of the way somewhere say under the dash.
