Eventually, you'll need to replace the light bulbs on your Mk4 Jetta. Replacement of the light bulbs is not an overly complex job, but there are a few unique ways in which the light bulbs are mounted within the car. In this article, I'll go over the steps required to replace nearly all the outside bulbs on your Jetta. Note that this article does not cover the replacement of the front fog lamps, as our project car was not equipped with them.

Right Headlight Assembly - Loosen and remove the two Phillips head screws (green arrows) and lift the access panel (yellow arrow) up and out of the engine compartment.

Right Headlight Assembly - Loosen and remove the two Phillips head screws (green arrows) and lift the access panel (yellow arrow) up and out of the engine compartment. This will give you more room to access the headlight housing below.

Left and Right Headlights: Use a screwdriver to pry back the retaining clips (green arrows) and remove the rear cover of the headlight assembly.
Figure 2

Left and Right Headlights: Use a screwdriver to pry back the retaining clips (green arrows) and remove the rear cover of the headlight assembly. Note that I have removed the battery in these pictures for better access. While it is possible to change the bulbs with the battery in place, removing the battery makes it much easier. The right side headlight assembly is much easier to work with.

Left and Right Headlights: You'll see the main high/low beam bulb directly inside the headlight assembly.
Figure 3

Left and Right Headlights: You'll see the main high/low beam bulb directly inside the headlight assembly. Rotate the locking ring (green arrow) and pull the headlight bulb out. This can be a little tricky.

Left and Right Headlights: Pull back the locking tab (green arrow) on the electrical connector and pull it off the headlight bulb.
Figure 4

Left and Right Headlights: Pull back the locking tab (green arrow) on the electrical connector and pull it off the headlight bulb. Installing the new headlight bulb is the reverse order of removal. Take care not to touch the glass part of the bulb with bare fingers, as the oil from your hands can damage the bulb when it gets hot.

Left and Right Headlights: The turn signal bulb is located inward of the headlight bulb.
Figure 5

Left and Right Headlights: The turn signal bulb is located inward of the headlight bulb. Press the tab (green arrow) on the access panel and pull it off the back of the headlight assembly.

Left and Right Headlights: Inside the assembly is the turn signal bulb.
Figure 6

Left and Right Headlights: Inside the assembly is the turn signal bulb. Turn the locking ring and pull the bulb out. Again, this can be a little tricky.

Left and Right Headlights: Pull the bulb (green arrow) out of the bulb holder.
Figure 7

Left and Right Headlights: Pull the bulb (green arrow) out of the bulb holder. Installing the new bulb is the reverse order of removal.

Left and Right Taillights - Open the access door inside the trunk to access the back of the taillight lens.
Figure 8

Left and Right Taillights - Open the access door inside the trunk to access the back of the taillight lens. Press the tab (purple arrow) on the electrical connector and pull it out of the bulb carrier. Now press the two tabs on the bulb carrier (green arrows) and pull the bulb carrier out of the taillight lens.

Left and Right Taillights - It's a tight fit, but the bulb holder comes out of the taillight lens with a little effort and twisting.
Figure 9

Left and Right Taillights - It's a tight fit, but the bulb holder comes out of the taillight lens with a little effort and twisting.

Left and Right Taillights: And here's the bulb carrier removed from the car.
Figure 10

Left and Right Taillights: And here's the bulb carrier removed from the car. The individual bulbs are replaced by pressing them down slightly and turning them. Installing the new bulbs is the reverse order of removal.

Left and Right Side Lights: The side light bulbs are replaced by using a small screwdriver to pry the side light housing out of the fender.
Figure 11

Left and Right Side Lights: The side light bulbs are replaced by using a small screwdriver to pry the side light housing out of the fender. Start from the rear (green arrow), and take care not to damage the paintwork.

Left and Right Side Lights: Pull the bulb socket (green arrow) out of the side light housing.
Figure 12

Left and Right Side Lights: Pull the bulb socket (green arrow) out of the side light housing.

Left and Right Side Lights: Pop the old bulb out of the socket (green arrow), and install the new one in its place.
