I would think so. I have LED parking lights and they blink very fast as if a light is out.

Really? So if I put resistor, it'll be not blinking so fast right? Thanks

I would figure that the way to system works is that it doesn't have a certain amount of resistance from the bulb, then it will blink fast, notifying the driver a light is out. LED bulbs don't put up the same resistance as OEM style ones, so the system doesn't recognize a bulb being there, even though it lights up like normal. I would figure if you put a resistor on it would clear up that issue. I just am not that bothered by it. Lol

its not blinking fast because of the resistor..a resistor only restricts voltage to the LED from the main power source so they dont blow.

Example: 1 2.2volt LED needs a resistor in order to handle 12volts from your car.the more LEDs you add the more resistance you'll need.

If you just connect an LED straight to 12volts it will blow.if you connect alot to 12volts the will be dim.

Anytime you use an LED on 12volts you need a restr, useless you bought the light setup the restr should be preinstalled.

You don't need resistors for the back up lights I put led bulbs in mine and they work fine! And they look sweet! There not as bright but I don't go places where's there's no lights when I back up so I don't need blinding reverse lights they just add a nice touch but no you don't need resistors

A bulb is different than an LED.rstrs are preinstalled on bulbs to handle the extra current.on a plain LED you must install a rstr.or it will burnout. I attached pics of the LEDs i am referring to, if you are using a manufactrd replacemnt BULB..maybe thats how it functions.
