Question about Black Diamond Cosmo Headlamp

Open Question

I've got a Black diamon cosmo headlamp which main lamp goes off about a tenth of seconds after I turn it on. Still, keeping the button pushed makes a really (REALLY!) dim light appear. The other lamps are just working fine for my batteries are new. Any idea? (please?)

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

Twilight sentinel will not work; now headlight and tail lights won't come on; interior lights still work with knob. Do you think it is the F-switch? Also, where can I get a schematic of how to ins


It's probably the lighting control module , but without doing some electrical testing that is just a guess !
Battery positive voltage (B+) is applied at all times to the lamp control module (LCM) through the underhood junction block HDLP MaxiFuse® and CKT 1242 (RED).
When you place the headlamp switch in the HEAD position, the headlamps input to the LCM is grounded. The LCM then applies battery positive voltage (B+) through the underhood junction block HDLOBML fuse and HDLOBMR fuse, which feed the left low beam headlamp and the right low beam headlamp respectively. When you activate the headlamp dimmer switch by pulling on the multifunction lever until the switch clicks, CKT 524 (PPL) is grounded to the LCM. The LCM then removes battery positive voltage (B+) from the low beam headlamps and supplies battery positive voltage (B+) through the underhood junction block HDHIBML fuse and HDHIBMR fuse, which feed the left high beam headlamp and the right high beam headlamp respectively.

Twilight Sentinel Circuit Description
Twilight sentinel determines whether the daytime running lamps (DRL), or the exterior lamps and the low beam headlamps at full intensity should be on based upon the signal of the ambient light sensor. When the ambient light sensor detects daytime, the twilight sentinel turns on the DRL. When the ambient light sensor detects darkness, the twilight sentinel turns on the exterior lamps and the low beam headlamps at full intensity. The twilight sentinel also keeps the lamps on for a delay period of 3 to 180 seconds under the following conditions:
• The vehicle is in PARK.
• The ambient light sensor detects darkness.
• The ignition switch is turned to the OFF position.
You may turn off the twilight sentinel manually. When it is dark and the gear selector is in PARK, pushing the twilight sentinel switch to OFF will turn off the headlamps and exterior lamps. Pushing the twilight sentinel switch to OFF again will turn on the headlamps and the exterior lamps. If the gear selector is not in PARK, pushing the twilight sentinel switch will have no effect.
The F- switch is just an input from the LCM - lamp control module .
Do you know how to test control module inputs an outputs ? Very easy to fry a module if you don't know how to do it .
Also have a full scan of all modules on the vehicle , could have DTC'S - diagnostic trouble codes stored . Not for the OBD 2 engine computer . The instrument cluster , BCM , LCM can all set codes too, related to lighting an someother thing's .

Electric Testing Techniques You Need to Know

You can find free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine ! Under system click on lighting ,then under subsystem click headlamps . Click the search button then the blue link . The first diagram you will see at the top the power supply to the LCM , down a little you will see the headlamp switch , ambient light sensor . Now if you want to start replacing thing's without testing good luck !

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 get in to change the headlight bulb on the 2004 Dodge Dakota


Remove the single torx screw holding the parking lamp assembly to the headlamp assembly. Remove the parking lamp bulb and sockets from the main assembly and set aside. Remove the three bolts holding the headlamp assembly. Pull the headlamp assembly forward off of the alignment pin and disconnect the harness from the back of the bulbs. Turn the bulb holder and pull the bulb out. Replace in reverse. Total replacement should take 15 minutes. Gregg

Thanks for the tips Gregg! Indeed, don't work anywhere but in front of the grill. Notes from my adventure:
You'll need a t-10 torx skinny screwdriver, and a 10mm socket wrench/driver.
Find the little torx screw near the bottom side of the headlight nearest the wheel and remove it. Tug and wiggle on the turn signal unit and it'll come loose. You'll find three 10mm bolts that hold the headlight unit in. More tug and wiggle and the unit falls free. After bulb replacement (don't touch the glass or finger oils can cause it break under high heat) replace the headlight unit. You'll see little plastic guides that the signal unit slides into- replace the unit and the tiny screw that holds it all in place. Replace the other bulb too, the second one takes a tenth of the time :)

This works on a couple different Toshiba models -- might work on yours...

Make sure the main power switch is OFF. Hold the "ON", "MENU", and "INPUT" buttons at the same time and turn the main power switch on. Keep them held until the yellow power standby light comes on, then let go. It is done.
