Bring Your Silverado or Sierra LED Headlight Back
The LED driver module powers and controls the factory LED headlamp. When it fails, the headlight can flicker, go dim, or stop working, and a headlamp warning may appear on the dash. Replacing the driver module with the correct GM part is often far cheaper than replacing the whole headlight assembly.

Installation (2019-2022 Silverado 1500 / Sierra 1500 with LED Headlights)
High-level steps for the 84547823 driver module. Access differs by trim and grille style, so use a service manual for your exact truck.
- Power down. Turn the ignition off and disconnect the negative battery cable.
- Free the headlamp. On these trucks the headlamp is usually held in by the grille and upper front fascia. Remove the upper radiator cover and the grille/fascia fasteners as needed, then unbolt and pull the headlamp forward.
- Remove the old module. The LED driver module mounts on the back of the headlamp housing. Unplug its connector and remove the module.
- Fit the new module. Mount the 84547823 module in the same spot and plug the connector in until it locks.
- Reassemble. Reconnect the headlamp harness, reinstall the headlamp, grille and fascia, then reconnect the battery.
- Program the module. GM lists 84547823 as programming required. Have it set up by a GM dealer using GM SPS, or by a shop with a GM-capable scan tool.
- Test. Check low beams, high beams and DRLs on both sides, and confirm no lighting warnings on the dash.
