A short time ago, the dashboard bulb failure indicator light came on. The passenger side brake light bulb had loosened and dislodged. Once replaced the indicator went off. When it happened again, the bulb was replaced, looked like a faulty pin on the bulb. Since then (not sure if the two things are connected) the dashboard indicator comes on and goes off at varying intervals (sometimes the same day, sometimes after a few days), but when checked all the lights (interior and exterior) are working. Any thoughts? Is it maybe a dashboard problem as opposed to the lights? Help appreciated - garage is struggling to find the problem to fix.
