Does anyone do these to kill tail lights, drl's reverse lights, interior lights etc? Specifically on 2008+ Chevrolet Silverado 2500's? Just curious to see what others have done. I know there's huge liability involved and most don't like to do it. And if I remember right D 'n R carries a module to help with this. I don't need this module, plus the customer probably wouldn't pay for it so I'd just use a switch and a couple of relays. Thoughts?
