For example, some types just have one warning light that illuminates when there’s a fault within the brake light circuit. Others are fitted with two lights, one among which acts as a systems check and illuminates whenever the pedal is pressed to point that the circuit is okay. the opposite light – usually red glows to point there’s a fault within the circuit.

With the latter type you’ll fit the control unit almost the brake lights at the rear of the car and mount the red light on the dash itself or during a bracket secured to the dash.

1. Mount warning light

Disconnect the battery. If the red light is to be mounted on the dash, find an appropriate position and drill out a hole for it. If it’s mounted during a bracket to the underside of the dash, drill two holes and secure the bracket with self-tapping screws. Then fit the red light to the bracket.

2. Fit control box

The monitor control box is mounted inside the boot near to the rear brake lights using a self-adhesive pad. Remove any trims or covers from round the taillights .

4. Wire warning light

Route the 2 red light wires back from the control box, under the carpets, to the red light . Join the 2 wires to the 2 terminals on the red light . employing a Scotchlok connector, tap an extra wire into the red warning-light-to-control-box wire, then join this to a fused, ignition-controlled feed.

5. Earthing

Find the world wire attached to the control unit. Run it either to an existing earthing point or drill a small hole within the bodywork and secure it with a self-tapping screw. you’ll need to rub the paint right down to the bare metal to urge an honest contact. Smear the reference to vaseline to stop corrosion.

6. Testing

Reconnect the battery. activate the ignition and therefore the red light should illuminate for a few seconds. Remove one among the stoplight bulbs and depress the pedal —the red light should illuminate to indicate the fault. If the sunshine fails to illuminate recheck all the wiring.

When Did the Brake Warning Light Show Up?

If the brake red light comes on and stays on when you start your vehicle, don’t begin to drive it. Turn your car off and inspect the possible causes of the difficulty (we will get to those soon).
