Today I installed Nixon Offroad LED taillights that had plug n play resistors that came with it on my ‘03 3500. Previous taillights were LED with exception to the reverse bulbs and the new are all LED. Old lights did not have the lamp out problem. New lights triggers the lamp out for a split second on the release of the brakes. Lamp out stays on while the indicators or hazards are on but remains off if the indicators and brake are engaged simultaneously.
