With an LED current is dependent exponentially on the voltage in the diode. This means that a small change in voltage can cause a large change in current.
If the maximum voltage rating is exceeded by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED.
The typical solution in electronics is to use constant current power supplies, or driving the LED at a voltage much below the maximum rating.
Since your Jeep battery/alternator/voltage regulator system is not a constant current source, does your LED fixture include a power converter?
Just interested in how it is going to handle the voltage changes. These LEDS are more sensitive being semiconductors than the incandescent lamps or the HID discahrge lamps.
The voltage at the battery in a standard setup is about 14V with the engine running but out at the end of those little bitsy wires at the headlights drops to nearer 11V, sometimes lower. The lower voltages will protect the lamps BUT the amount of current is exponential to the voltage so the light levels must have a much larger drop.
