The chrome taillights have never looked quite right to me, at least on a black truck.  I replaced them with some "Bermuda Black" taillights from Adjure:

Fit and finish are near OEM.  My only installation tip:  use the OEM screws rather than the ones provided.

If you have condensation problems (I had mild problems), then you need to drill a couple of tiny holes to allow the humidity to escape.  Drill very slowly and keep blowing the plastic shavings away.  Drill from the bottom up into the light.  When you are just about to break through, finish the hole off in reverse.  If you get any shavings inside the light, keep it upright and try to coax them out.  If the shavings are on the second hole (I drilled one top and bottom), and are near the hole, then a blow gun into the opposite hole will force the shavings out of the hole you just drilled.

Our beds are open top and bottom, so I was concerned about water and dust getting inside.  So I cut tiny pieces of t-shirt fabric and taped them over the holes to act as filters.
