Not sure on the speedo.

The night light? PArking light? If you mean parking light, you probably need a bulb. There is a double filiment bulb that will light when brake is on and slightly dimmer with the parking light.

Would you call the knocking a rattle, like marbles in a tin can noise?

Yeh the speedo light not working is annoying, but i've changed the rear light bulb with the double filament and it still doesn't work.

The knocking is kind of like a low pitch sort of sound like a golf ball continuously hiting the underside of the car near close to my feet

Is is possible that the exhaust moves into a postion that is is bumping the floor? OR a heat shield that is moving at the higher speeds? Stick you nose under and do a little feeling around for anything that may be loose.

You'll need to check for power and good ground back to that socket if the bulb is good and installed correct. Sometimes there is a ground tab that needs a little manipilation.

Not necessarily. When your in fifth gear, you are running at higher speeds and have an increased air flow throughout the car. IF you stick your arm out the window with a loose jacket on you'll see how the sleeve flaps like crazy. Now hold you hand out flat and slightly pitch it like a flap on an airplane. You whole arm goes up and down as you change your flap..err hand. Transfer that theory to the car. A loose heatsheid that is thin will do the same. It may be pushing up on something such as a hose. It can be moving itself or somthing else and hitting the floor board or anthing that transfers the energy to your feet.

Suggested Repair

Inspect underneath for a loose heat shield or exhaust that contacts the floor at higher speeds and secure anything loose. For the rear parking light, confirm the dual-filament bulb is correctly installed, then check power and ground at the socket, including the ground tab. The speedometer lighting was not diagnosed.

Conversation Summary

The owner of a 1993 Mitsubishi Galant reported inoperative speedometer lights, a rear parking light that still failed after a dual-filament bulb replacement, and a low-pitched knock near the feet in fifth gear above 90 km/h. The expert said the knock may come from a loose heat shield or exhaust moving in the increased airflow at higher speed, and advised checking underneath. For the parking light, the expert recommended verifying power and a good ground at the socket.
