Colyn. Look into cree leds for your reverse. I plan on doing some stock silvy tails (if I can't get mine back to red) and cree leds and remove the bumper lights.
A few of the guys on the Duramaxforum have run these with out an isuue
Well I pulled the trigger on some 55w 5k for the bumper from vvme I can let you know when they come in of the quality compared to some of the bast companies I've used
I was going to do the switchbacks but with some people having issues with trying to get them to work properly they just arent worth the extra cash to me
Buddy of mine is going to help me install them and do the wiring to swap from drls sockets to turn sockets in bumper lights that way it will be all white when driving then when I turn that whole light will flash orange...
My 194's were from V-led's. Switchbacks worked awesome for a couple months, then they started to flicker when ever i took the truck in and out of park. And if I had the fogs on the driver side would not return to the running color white. My connections were all good on the resistors too. Said fawk it and removed them.
