I purchased a pair of license plate bulbs from vleds. Im very happy with their performance ( very bright white light) and only cost me $12 shipped. Got them bout 4 days after ordered. I've decided to replace my backup lights with vleds bulbs as well so when I use my key fob the lights will light up brighter behind the vehicle. Are these just a plug and play or is there more to them. I have heard that TB's are tempermental with the lights and I know turn signals need the flashers upgraded so they dont flash super fast with leds.
