3.) Once removed, you will see a circular plastic cap that covers the DRL bulb, twist and remove it.
4.) Remove the DRL bulb holder from the socket and remove the bulb. Please be advised that the passenger side is much more difficult than the driver side. Removal of the headlight is highly recommended for an easier installation.
