Step 3: Remove Fender Flares and Lower Valance

To access the bolts for the factory light, you'll need to remove the fender flares and lower valance.

Turn the hinges on the fender flare to the unlocked position. Remove the flare by hand.

Next, unclip the lower valance underneath the light. Repeat this process on the other side.

Using an 8 mm socket, unscrew the bolts holding the headlight in place. Remove the headlight from the housing. Repeat this process on the other side.

Pro Tip:When you're pulling out the factory light, you may feel some resistance. This is because of a plug meant to hold the light in position. Just give it a solid pull to remove it from your Bronco.

Step 5: Adjust Lighting Settings

Use a Phillips-head screwdriver to remove the four screws on the outside of the LED wiring housing. On the inside of the wire box there'll be two wire plugs. Deciding which of these wires to plug in will determine the light setting you'll have.

For an all-white headlight with a white bar, leave both plugs unconnected.

For a white circle with an amber bar, connect the top two red wires. Leave everything else unplugged.

For an all-amber look, plug in both side connectors.

For an amber circle with a white bar, only connect the plug on the right.

Once you have your chosen setting, reassemble the wiring box. Repeat this process for the other side.

Step 6: Install New LED Headlight

Plug in the new LED housing to the factory wiring harness. Reattach the bolts for the light. Repeat this process for the other side.

Once both new lights are connected, reinstall the fender flares and lower valance. Unlock the fender flare hinges, reinsert it, and relock the hinges. Snap the lower valence back into place. Reinstall these parts on the other side.

Reinstall the grille with the factory bolts, then reinsert the front trim panel.
