Routine Check

For your own safety, check the brake lights as often as possible.


PROCEDURE

When you press the brake pedal, the garage wall behind your vehicle should flash light red on both the left and right sides.

When driving in a line of traffic, you can see in the interior rear view mirror whether both of your brake lights are reflected in the headlight reflectors or on the paint of the vehicle following you.
