check the wiring harness beside the hinge that moves when you close the trunk.i have seen the wiring get pinched and the ground gets broken. the tail lights have separate left and right side fuses.get a test light,and with the ignition in the on position,there should be power on both sides of all the fuses.the atc type have little test pins on them.ground the test light and put the tip on the fuse.if there is power,the light will come on. if a fuse does not light up the light on both sides,it is open.since the fuses are see thru,it is apparent if it is blown as the metal inside will be burnt.

P0420 is "catalyst system below efficiency". It means that the car thinks a catalytic converter is bad. It could be that the cat is failing, but it also may be that the secondary oxygen sensor (behind the cat, used as a comparator to determine the health of the cat) is failing. As that part is about 10% of the cost of a new catalyst, I'd replace it first, have the code cleared, and see if it comes back.
