Owners of any Smart Fortwo models or trim levels such as the coupe hatchback, cabriolet or "cabrio", electric, pure, passion, forfour, prime and proxy may also find these DIY instructions to be helpful.

The compatible replacement light bulb part numbers are as follows: Low Beam # H7, High Beam # H7, Front Turn Signal # 2357A (or 2357NA) and Front Side Marker # 2827 or WY5W.

No tools are needed to access and replace any of the light bulbs in either the driver or passenger side headlight housings.

Gently push in the release tab on the black plastic lever in towards the center of the car before swinging it open towards yourself.

Repeat the process for the lever on the other side of the black plastic grille.

Pull the service flap slightly forward towards yourself.

Once the two black plastic tabs on the rear edge of the flap (closest to the windshield) are removed, you can pull it off the front of the car.

Hang the service flap on the front edge of the car.

I just put a towel on the ground and gently let it rest on the floor.

The low beam light bulb is located at the center of the headlight housing.

Then gently pull the black plastic power plug off the old low beam bulb.

Push in the metal loop near the top of the bulb socket and pull it down to release the metal retaining arms from their hooks.

Swing open the metal retaining arms down and off the back of the old light bulb.

Try to avoid touching the glass part of the new halogen H7 low beam light bulb with your fingers or anything greasy in the engine bay.

If you do get the new bulb dirty, wipe it clean with a paper towel and some rubbing alcohol.

Insert the new # H7 low beam bulb in to the housing.

Push the top of the retaining clip forward and up to secure it in the two metal hooks.

Push the power plug on to the base of the new low beam bulb.

Push the rubber cap back in to place over the low beam bulb housing.

Pull the black cover off the back side of the high beam housing.

Gently tilt the old high beam bulb down and pull it out of the housing.

Use a flathead screwdriver to gently push in the metal tabs to release the old high beam bulb.

Push the electrical connector straight on to the base of the new high beam bulb.

Re-attach the rubber cover on the rear of the high beam housing.

Rotate the grey plastic turn signal bulb socket 1/4 turn counterclockwise before pulling it straight out of the housing.

Push a new amber colored number 2357A light bulb down in to the socket and rotate it 1/4 turn clockwise to secure it in place.

Re-insert the bulb socket in to the housing and rotate it 1/4 turn clockwise to secure it in place.

To remove the front side marker bulb socket, you have to rotate it 1/4 turn towards the outside of the car.

The side marker light bulb socket removal procedure is the same for both the driver or passenger side headlight housing.

Just twist the bulb socket towards the outside of the car.

Push in a new amber colored number 2827 or WY5W light bulb straight in to the socket.

Re-insert the bulb socket in to the housing and rotate it 1/4 turn towards the inside of the car to secure it in place.

Re-insert the two black plastic tabs on the rear edge of the service flaps in to their corresponding slots on the cowl.

(The cowl is the black plastic area in between the service flap and the windshield.)

Push down the front edge of the service flap.

Push in the two levers to secure the retaining clips.

Double check that the service flap is securely in place.

Be sure to record the headlight bulb change in your car's service records.
