Purchased a set of power seat switch bezel trim appliqués from this website. Installation was easy, about five minutes per side (98% of this time was cleaning and waiting for the adhesion promotor to setup), They add to the seat trim, or at least I think so, and the price was not bad. Went with the brushed to match the I/P center trim panel.
Also, installed the front HUMMER letter inserts in polished stainless steel to match the polished grille.
