These are the lights that go on the tailgate, and dually fenders on dually pickups. They are incandescent bulbs, just as the original ones were on your truck.
The factory used 2 amber lenses on the front of the dually fenders, and 2 red lenses on the rear. There was also 5 lenses on the bottom of the dually tailgates.
Don’t forget to order the black mounting base if you need them.
Lenses sold individually.
