replaced all the interior lights w dd leds, great quality. the tail as turn module with mid-grade dd leds is like having a reverse lightbar. the net/net is it uses the brake light as a turn signal, and the turn signal as an aux reverse light (2turn + 2 rev = 4 rev lights). i have a very dark driveway and it's a huge improvement. i dont like stuff tacked on the outside of the truck, ie flood pods. this is a no brainer. no affiliation, just impressed. super ez install too. thumbs up. have their fog lights ill install next weekend.
