Disconnect the Negative Battery Terminal

Before disconnecting the negative terminal of your battery, ensure your truck’s engine is off and completely cooled down.

Create More Space

Locate it and disconnect it. When you twist the connector in some trucks, the bulb will come out from its housing. 

Fix the New Bulb

You should never touch the bulb with your bare hands. Use the base of your new headlight bulb to fix it. Ensure the fixing is done correctly.  

Reassemble Everything

After ensuring that your bulb is firmly fixed, and secure, put back the headlight housing, plug it into the connector and connect everything you disconnected to create room. Connect your battery and tighten everything. 

Test Your New Headlight

After ensuring everything is well connected, turn on the high and low beams. Just to be sure that the bulb is working properly. If it is dark, ensure the bulb is sitting correctly to distribute light evenly.
