Hello,
Bulb TVs are very big. In most cases the TV will give a warning that alerts you it's time to change the bulb. Do not touch the glass part of the bulb, as oil from your hands will reduce the life span of your bulb. Replacing the bulb is a simple process that will take a few minutes. Here is how to do it.
Step 1: Read User Manual Make sure that you have your user manual with you when working on your TV. Most electrical appliances will have guides on how to deal with replacements of parts and where to get the replacements and what specifications to look for. Read the user manual in depth before attempting the project of replacing the bulb. Step 2: Disconnect Power When working with any electrical appliance, always switch off and disconnect the power. Electrical shocks can cause injury or even death. Step 3: Open Bulb Door At the back of the TV there will be a bulb door which will usually be near the power cord, depending on the make of the TV. Once you locate the door, proceed to open either by sliding it open or unscrewing it as may be required. Step 4: Remove and Replace Bulb Once the door is open, unscrew the bulb assembly and remove it. You can then remove the bulb from its compartment. Bring out the new bulb. Hold up the groove on top of the new bulb and align with the groove pocket on the inside of the TV, then proceed to slide the new bulb into place. Step 5: Replace Bulb Assembly Once the bulb is securely held in place, return the bulb assembly to its position and screw it back. Make sure not to tighten it too much but have the screws just firmly in place. Step 6: Close Bulb Door Once you are finished, you can close the bulb door after making sure there are no tools or screws left inside. Having such items inside the TV could cause a short circuit. Your door needs to be closed for the TV to operate. Tips: Remember to allow the old bulb to cool before you remove it. It will usually heat up to very high temperatures that could cause some serious damage. Most TV bulbs will warn you to replace your bulb while about a hundred hours are left on the old bulb. This duration is meant to give you time to get the replacement bulb and fit it. Finally, if you do not feel confident in doing the replacement yourself, get a professional to do it for you. They might charge you a fee, but it will be cheaper than the cost of damage caused by a poor fit.
Take care in solving the fault

Headlight bulb chevy traverse life


As I also had the dealer tell me it would be $120 - $150 to change I looked into it further. If you will remove the screws from the protective cover under the fender (just a few you do not need to remove the full fender cover). You can access the bulb. You will need to turn the housing and remove the bulb. Be sure to not touch the bulb as oil from your fingers will make certain you will be changing the bulb in a short time. Also I would use the standard bulb as the brighter bulbs run hotter and burned out very fast (2-3 months). If you turn the wheel your access to the bulb is easier. It is tight but by changing the bulb yourself you are saving a lot of money.

New signals not flashing


Depending on the year of your bike, If you changed your signals from a bulb type to a LED type you will need a Load equalizer. If its a bulb to another bulb, Check your voltage at the housing. A change in amps or watts for the bulb will usually only change the brightness, unless you have changed the bulb to an outrageous wattage or amps.

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.
Remove the headlamp bulb/socket from the headlamp assembly.

Left xenon ligth is not out... but has changed color from the cool blue ... to a slight pinkish color? is it the bulb or something else


xenon bulb has two electrodes and they will erode away if the bulb is old. The color that you see is probaby the erotion of the electrode mixed with the inert gas and metal halide. All HID bulb will change color over time. For example a brand new 4300K yellowish bulb will eventually turn into a 5000k color bulb which is purple and white

If your bulb is not too old but the colour has changed then that means your bulb has premature problem. Frequently switching on and off the bulb can age the bulb by up to 50%.

I strongly recommended to change both bulbs, so they have even color.
