Hi guys,
Recently bought myself a 2004 mazda 3 , excellent car and is a beautiful example but I have a question to ask you guys.

Have you ever heard of the the interior lights( dash lights) effecting the rear lights?
When I turn on the lights for the car the dash lights and rear lights are intermittent. They will turn on and off at the same time. The front lights are fine though.
Took it to mazda and they said it was a problem with the front light holder as it was corroded. It's been replaced however it's still happening.
Do you think it's a wiring job?
Any thoughts are appreciated

Thanks guys.

James
