    Tail light flashes fast

    Hi Folks,
    Had to replace my left tail light in my 2007 DTS. Bought one on Ebay for a 2006 and it flashes at about twice speed.
    I am guessing the internal resistance of the unit is lower for the 2006 than the 2007.
    I am also guessing that I can install a resistor to correct the problem.
    From what I have deduced the yellow wire would be the correct place to do this.
    Any suggestions other than buy the 2007 light?
    Anyone run across this?
    Thanks in advance....

    Check the LEFT FRONT turn signal ...
    See if it is also flashing fast or maybe not flashing at all.

    The left front is also flashing fast. Apparently the resistance of the 06 tail light is different than the 07.
    Just looking to see if someone had an easy fix here...thanks for your reply.
