2003 head lamp assembly

I just bought an '03 Disco. My driver side headlamp was out so i took out the assembly to replace it. The bulb still looked good but I swapped it anyway and i worked fine. Later that night I walked in front of the Disco and the new bulb was out too. I can only guess that it is the wiring that is bad. I also have other indicator bulbs that are out and when I put the right turn indicator on my trailer directional dashlight comes on. Any help here.... ?

    I actualy found the issue when I was following the wires backwards from the lights. On the harness one of the pongs were bent and it was not making a ood connection. Pretty elementary issue, but it's fixed. And yes I made sure I handled the bulbs with a clean rag.

Did you touch the glass on the new headlamp bulb?
Your sweat from your fingers will cause the bulb to blow because halogen lights heat up really quickly.
Check the earth(negative) wires around the rear lights and also check the socket for your trailer.
Slight corrosion will cause all sorts of problems.
It`s always worth checking earth connections just to make sure you can rule that problem out in the future if a bulb blows.
Hope you understand me. If not I will try to make it a bit simpler.
My wife says I can fix computers, cars and washing machines but can`t work a vacuum cleaner round the house.

How do I replace the headlight assembly MN133516


The 2003 Outlander utilizes replaceable (9007) headlight bulbs. If you're looking to replace the bulb(s);
1. Raise the hood.
2. Remove the plastic cover at the rear of the headlamp assembly by rotating it counterclockwise, and pulling it off. This will allow access to the headlight bulb.
3. Twist the bulb socket counterclockwise in order to remove it from the headlamp assembly. Pull the old bulb out of the socket, and use a clean cloth to install the replacement bulb. Do not touch the glass of the new bulb.
4. Place the socket back into the assembly, and twist it clockwise. Reattach the plastic cover, and close the hood.
Are you needing DIY instructions for replacing the entire headlamp assembly? Left (driver) or Right (passenger)?

What is the process for replacing the headlamp


Replacing headlamp bulbs
Handle a halogen headlamp bulb carefully
and keep out of children’s reach. Grasp the
bulb only by its plastic base and do not touch the
glass. The oil from your hand could cause the bulb
to break the next time the headlamps are
operated.
If the bulb is accidentally touched, it should be
cleaned with rubbing alcohol before being used.
To remove the headlamp bulb:
1. Make sure headlamp switch is in OFF position,
then open the hood. If you are replacing the driver
side headlamp, unclip the electronic module on the
right side of the battery and move it out of the way.
2. Locate the headlamp bulb through the hole in the
upper radiator support assembly.
3. Release clip and
disconnect the
electrical connector
from the bulb.
4. Remove the bulb
retaining ring by
rotating it
counterclockwise
(when viewed from the
rear) about 1/8 turn to
free it from the bulb socket, and slide the ring off
the plastic base. Keep the ring to retain the new
bulb.
5. With out turning, remove the old bulb from the
lamp assembly by gently pulling it straight out of the
lamp assembly.

To install the new bulb:
1. With the flat side of
the bulb’s plastic base
facing upward, insert
the glass end of the
bulb into the lamp
assembly. You may
need to turn the bulb left or right to align the
grooves in the plastic base with the tabs in the lamp
assembly. When the grooves are aligned, push the
bulb into the lamp assembly until the plastic base
contacts the rear of the lamp assembly.
2. Install the bulb retaining ring over the plastic base
until it contacts the rear of the socket by rotating
clockwise until you feel a “stop.”
3. Install the electrical connector into the rear of the
plastic base until it snaps, locking it into position.
4. Turn the headlamps on and make sure they work
properly. If the headlamp was correctly aligned
before you changed the bulb, you should not need to
align it again.

How do I change the back turn signal on my 2001 ford taurus


DIY - 5 Minute Turn Signal Bulb Replacement This is very simple to do. First you will need an 8mm socket and wrench to loosen one bolt. Second a good long flat head screwdriver. There are two black metal folded tabs behind the headlight assembly and one 8mm bolt holding it in plae at the center point of the front of the car. Loosen the bolt and remove. Use the screw driver to pull up the metal straps and then slide forward the entire assembly. This will slide easily unless your front bumper has been bumped! That will make it a little difficult to slide if it is out of alignment. If it was never bumped than this should take all of 5 minutes.

Replacing front parking lamp/turn signal/cornering lamp bulbs
  1. Remove headlight / lens assembly per below steps mentioned later

  2. Rotate the bulb socket of the offending bulb counterclockwise and remove from the lamp assembly.

  3. Carefully pull bulb straight out of the socket and push in the new bulb

  4. Install the bulb socket into the headlight assembly by rotating it clockwise

  5. Re-install headlight assembly - hold snugly into place until the brackets line up and retainer pins can be pushed down

To replace headlight bulb:
  1. Make sure headlight switch is turned OFF.

  2. Remove the bolt at the end of the headlamp housing.

  3. Pull the two black tabs with the L shaped bracket toward the back and then up and pull out(Located at the back of the headlamp) to release the headlamp assembly from the vehicle and pull headlamp assembly forward.

  4. Disconnect the electrical connector from the bulb by pulling it.

  5. Remove the bulb socket retaining ring by rotating it counterclockwise.

  6. Remove the bulb from the lamp assembly by pulling straight back.
    Do not twist, as there are alignment slots built into the lamp assembly socket.
    It may take some effort to remove the lamp because it has a rubber o-ring type seal - try a bit of wiggling side-to-side

  7. Insert new bulb into headlight assembly - don't touch the glass - use gloves, paper towel, or similar
    Make sure that the flat surface of the bulb socket is facing upward, and is firmly seated

  8. Re-attach retainer ring by rotating clockwise

  9. Reconnect the electrical harness

  10. Re-install headlight assembly - hold snugly into place until the brackets line up and retainer pins can be pushed down

NOTES
  • Do not touch the glass of the new halogen bulb - the oils in the skin will shorten the life-span of the new bulb, or possibly cause the bulb to explode when first turned on

    If the bulb is accidentally touched, it should be cleaned with rubbing alcohol before being used.

How do you remove the head lamp assembly on a 1993


1. Make sure headlamp is off and open hood.
2. Taurus model years 1990-1999: you must remove the whole headlamp to replace the bulb. Not a horrible task. Just annoying.
3. Facing the driver's side headlamp, and looking at the headlamp itself, at clock positions 8, 11 and 1 are the headlight housing screws. They all look the same. Using a 10mm socket wrench, remove these 3 screws and set them aside.
4. Just to the right of the "11 o'clock" housing screw is a bolt (same hexagonal 10mm sized top as the housing screws). This just needs a few turns to loosen it.
5. Gently pull the whole headlight forward. Now you can get at the bulb.
6. Disconnect the electrical connector from the bulb. Now the headlamp is free to work with. Remove the bulb, replace with a new bulb, make sure the bulb housing cylinder is in place and reconnect the electical.
7. Place headlamp back into position. Line up screw holes. Tighten the bolt. Replace housing screws and tighten.
8. Passenger side headlamp is mirror image of driver's side. Screws at 11, 1 and 4 o'clock positions. Bolt should be to the left of the "1 o'clock" housing screw.

I have 2006 Grand Prix How do I change head lamp?


Caution Halogen bulbs contain gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:
Turn off the lamp switch and allow the bulb to cool before changing the bulb.
Leave the lamp switch OFF until the bulb change is complete. Always wear eye protection when changing a halogen bulb. Handle the bulb only by its base. Avoid touching the glass. Keep dirt and moisture off the bulb. Properly dispose of the used bulb. Keep halogen bulbs out of the reach of children.
Raise the hood.
Remove the headlamp assembly bolts from the upper fascia support.
Slide the headlamp assembly outward enough to release the headlamp bracket tabs from the slots in the upper fascia support.
Position the headlamp assembly away from the vehicle body to access the electrical connector.
Disconnect the electrical connector from the headlamp assembly.
Remove the headlamp assembly from the vehicle.
Disconnect the electrical connector from the headlamp bulb/socket.
Remove the headlamp bulb/socket retainer ring from the headlamp, by turning counterclockwise.

I need to replace the driver side low beam headlamp bulb, but the bulb itself can't be removed. I have removed the battery for easier access. HELP !


The low beam bulb, drivers side, can be replaced by removing the entire headlight assembly, unplugging the electrical connection to the bulb, "pinch" the retaining clip on the bulb and the bulb comes right out. The only problem is the cost of the bulb---about $ 140. The replacement took about 45-50 minutes to complete.
