LED's are semiconductor devices that need current limitation. Resistors are the prevalent way of limiting current in a DC circuit. As long as the current running through an LED does not exceed the maximum allowable current figure for a particular LED, the device will continue to operate for a long, long time.
It is highly likely that LED's manufactured specifically for incandescent bulb replacement in automotive applications have a resistive element built into the plug which guarantees current limitation - or else the installation instructions that come with the device should provide clear guidelines on what is necessary to achieve correct operation.

The fact is that the suppliers think that if you are ordering it, you must know what you are doing so they don't bother printing anything.
