1. Disconnect the electrical connector: There's a connector holding the wiring harness to the bulb socket. Carefully unplug this connector. It usually just pulls apart, but be gentle to avoid breaking anything.
2. Remove the bulb socket: The bulb socket itself might be held in place by a retaining clip or simply friction. Gently twist or push it to release it from its housing. Some Ranger models require a little more force than others. Inspect the socket to see how it's held in. If there's a clip, try to locate it and gently release it.
3. Replace the bulb: Carefully remove the old bulb (it usually twists out). Ensure you get the correct replacement bulb; check your owner's manual or an auto parts store for the correct type and wattage. Insert the new bulb and twist it firmly until it's securely in place.
4. Reassemble: Put the bulb socket back into its housing, making sure it clicks into place. Reconnect the electrical connector securely.
5. Replace the cover: Put the red plastic cover back on and secure it with the two screws.
Important Considerations:
* Bulb Type: Make sure you replace it with the correct type of bulb. The wrong bulb can cause problems, including improper fit and incorrect signaling.
* Grounding: If the new bulb doesn't work, double-check the electrical connector and ensure everything is securely connected. A poor ground connection can also cause lighting problems.
* Safety: If you're not comfortable working on your vehicle, take it to a mechanic.
