Hi Patrick, Try pulling the two leads off of the brake light switch on your master cylinder. Then run a jumper wire between the wires themselves, turn the key on, and see if the brake lights go on. If they do go on, you have found the culprit - the switch is bad and needs to be replaced. This switch is frequently on Ebay. Did you change your brake system over to silicon brake fluid? This fluid type is known to eat up these switches one after another. So if you want to continue with the silicon fluid, buy several of the switches if you can get 'em. The other thing you can do instead is put a mechanical switch that is tripped by the brake pedal arm under the dash.
