One trick is having 10"or longer screw driver to push a tab down which releases that center body trim piece. . Theres a little recess in the Signal which allows you to push the tab down from above after removing the screws also inside the center kidney's there are similar plastic tabs which you need to depress ,screwdriver or such which were what i foudn was neccesary to do simultaneously while pulling out on the whole trim/grill assembly. Everything else is essentially self explainatory once you have the two sides out. Also be carefull not to touch the bulbs with your bare hands if you plant to reuse them but likewise if isnatlling them new. They burn right out if touched.
