Odd reverse light problem. Options

[bloodrain]

well, to make things simple, my reverse lights work when they want to. At first I thought they were completely dead (the bulbs), but then I noticed they will randomly turn on (when im backing up). I noticed there is a bit of corrosion inside the mounting part of the bulb (where the bulb meets the wires), cleaned that up, but still have the same problem. Also, my rear passanger side speaker ALWAYS blows out for no reason at all. Could these problems be related? and where can I even start to diagnose the problem?

Thanks for any help!

Alternately, it could be the actual sockets. I had to replace one of mine (brake light rather than back-up light, same idea however). When you install your bulbs, are you using dielectric grease to seal the connection? Cuts down on the corrosion issues.

Then again, with a tendency to blow a bulb, you might just have loose wires with a recurring short circuit.
