The most common problem is switch on side of transmission.(If bulbs and fuse are good)   Another common problem with reverse lights is a faulty ground.Check for the black ground wire off the lights in the back. If the connection to the ground (body or frame) is rusted or broken repair it.

It could be that the cruise is on Answer Never heard of a speed light. The only thing I can think of that you might be talking about is a shift light. This light is used to indicate shift points. Shift when the light comes on. All of the lights on you dash are explained in your owner's manual.

Answer The idle speed decreases to a set point as the engine warms up naturally. The engine when cold needs more fuel than air to stay idling. As the engine temp rises it tells the computer to cut back on the fuel and when it does it lowers the idle rpms. It is a natural thing. If your oil light …

Things (with mass) cannot be accelerated to the speed of light (or beyond) under any circumstances. That's because as an object is accelerated and its velocity approaches that of light, the energy used to increase its velocity is converted into mass.

At what are called relativistic speeds (some 90% the speed of light and more), time slows down appreciably. At the speed of light, time stops.
