Only if the LED fixture has built in current
or voltage regulation. The "cheap" way of regulating current
through the LEDs with dropping resistors will not protect them against over voltage damage.
If the LED assembly is rated for a wide range of voltages such as nine to thirty volts it will be fine. If it just says twelve volts, probably not.
