Diesel does "light" as do most flammable liquids. I am assuming that you mean why would diesel not light if I put a match/cigarette to it then the answer is as follows : Diesel is made up of "heavy" molecules made up of hydrogen and carbon. This means that it requires a lot of energy e.g. a high temperature to make them turn into a gas so that they will burn. The minimum temperature required for Diesel to ignite when a flame is applied (technical term is the flash point) for Diesel is above 62 degrees C hence even on a really hot day the diesel won't be hot enough to ignite. (The hottest day ever recorded was 59.8 degrees C in death valley US) In comparison the flash point of petrol (gasoline) is around -40 degrees C hence why it will quite happily ignite when a flame or spark is applied. This is why petrol engines use spark plugs but diesel engines don't.

Is diesel and light oil the same thing?
Diesel and light oil are not the same, although they are related. Diesel fuel is a specific type of light oil derived from crude oil, designed for use in diesel engines. Light oil, on the other hand, refers to a broader category of petroleum products that includes various fractions of crude oil, such as gasoline and kerosene, in addition to diesel. Therefore, while all diesel is a type of light oil, not all light oil is diesel.
