What kind of resistor or fuse should I use?

[misbehave]

I have bought a blinking LED to put into my P5 so make it looks like I have alarm system, which my car doesn't have.
I want to connect it to my car battery but I don't know what kind of resistor or fuse I should use to protect the LED from burning out because of power overload? The LED power input should be DC10.05-13.08V and <100MA if I read it correctly from the box.

You shouldn't need one
Whats its resistance

You shouldn't need one.

agreed... and sheesh.. even if it did fizzle out.. how much could an LED cost anyways? certainly not much unless you were ripped off.

I kinda find it weird that LED is got that much input.
They usually at about 2-5V input and you would need a resistor.
Unless its got one already.

many LED you can buy in the store have internal resistors, and or are made for 12V... you can get them for just about any voltage you want. but this particular LED has some circutry in it anyways, as it is made with a switching relay or something else to make it flash.
