" Q:  I have no brake lights on my 2006 Mazda5 van. It went thru inspection 3 months ago and I admit that I don&amp;#039;t preflight so I&amp;#039;m not sure when it occurred. They work sometimes with the key off or on but only with the engine not running. Is the brake light circuit still a &amp;quot;simple&amp;quot; circuit (fuse, switch, lights) or does a computer control the lights?  A: The brake light circuit is still a simple mechanical switch on the brake pedal. Should be trivial to troubleshoot. It might simply need adjustment. "^^<http://www.w3.org/2001/XMLSchema#string>
