Hi there,
Recently I had my front fog lamps/ driving lamps replaced and soon after the brake system warning light stayed partially illuminated even when the key is not in the ignition.

Anyone have any incite on where to look to solve the issue? There is no message on the dash and no codes come up with a reader. As well the brake fluid level is within range and the brakes seem fine.

If the light is on with the key out of the ignition then I think you have a wiring issue. There should be no Power going to the system when the ignition is off. It could be anywhere in the system. If the place that replaced the fogs did any wiring then they may have hooked power to the wrong place and it is back feeding into the brake system. It could also just be something internal in the instrument cluster.
