I replaced the driver's side HID bulb in my 2016 RS V6. The first indication that my bulb was burning out was that the color turned pink:
Step 1: Disconnect battery.
Step 2: Understand the bulb. The OEM HID bulb has a square base, a male connector, a glass bulb, and circular bezel that secures to the bulb socket of the headlight casing.
Step 3: Locate the cap for the HID bulb. You should be able to easily reach the cap following the arrow labelled 'Cap location'.
Step 4: Use the tabs on top of the cap to turn counter-clockwise and remove.
Step 5: After removing the cap, you will see the square base of the HID bulb and a (female) connector to the vehicle. Disconnect the vehicle connector by gently prying it from the HID connector with a small screwdriver. Note the orientation of the HID connector (the HID connector should be facing directly down toward the floor).
Note that there are two very small tabs on the inside of the vehicle connector that secure it to the HID connector. If there is not enough room to remove the vehicle connector from the HID connector, grab the square base of the HID and turn it counter-clockwise a few degrees until it no longer turns. Before pulling the bulb out of the socket, note the orientation of the HID base as you will want to insert the new bulb into the socket at this exact position. Next, pull the HID bulb out of its socket to more easily access and disconnect the vehicle connector from the HID connector.
Step 6: If you haven't already done so, remove the HID bulb by turning it counter-clockwise and pulling it out of its socket. Note the orientation of the bulb when pulling it out of the socket in order to insert the new bulb into the socket at this same position.
Step 7: View information on the OEM HID bulb to correctly identify and purchase new bulb. The OEM bulb is model D3S 35w.
Step 8: Purchase OEM HID bulb. I bought this from Pep Boys. For some reason, the box shows "Philips D3S C1" and not simply "Philips D3S"; I am not sure what the "C1" is for, but the SKU matches the original "Philips D3S" product.
The back of the box shows additional information:
Important: Note that counterfeit Philips bulbs exist in the market. Please check the bottom of the box to verify authenticity.
Step 8: Insert new HID bulb into the socket and turn clockwise to tighten.
Do not touch the bulb glass; only touch the square base of the bulb when installing. Reconnect vehicle connector to HID connector and reinstall cap.
Step 9: Reconnect battery.
Step 10: Turn on headlight and test.
