Well I could two ways with this respone the first being "A" the high road/the truth... yes the lights and bumper are very functional. Not only is our Tahoe my DD it is also our expeditionary vehicle and my emergency response vehicle, so these additions are serve there purposes very well. And of course there's "B" the low road/being a D-Bag, (insert extreme southern accent here) well them there lights and bumper are very helpful so i can see them there critters that like to run into me and kill em so I can take them roadkills home to my redneck bride and she cook us up some redneck stew mmmmm.
