So Fix it

The best fog light bulbs for automobiles produce white or selective yellow light. Fog lights are generally mounted low on the front of your car, aimed toward the road. This provides increased illumination of the road surface for low-visibility conditions such as fog, rain, snow or dust. Fog lights are not a legal requirement and should only be used for low-visibility driving situations. Misused fog lights can produce glare for other drivers as well as excessive foreground glare, impairing your driving vision.

White-Light Fog Bulbs

White light fog bulbs that use xenon gas are durable and long lasting. Further, xenon bulbs are significantly brighter than halogen bulbs. Buy white-light bulbs that do not emit blue wavelengths, as they can cause glare. The PIAA Coorporation makes high-quality white-light fog lights.

Selective Yellow Fog Light Bulbs

Selective yellow light bulbs improve visibility during inclement weather by removing the short wave lengths emitted by blue light. Blue wavelengths cause glare, especially during fog, rain and snow. The PIAA Corporations ion crystal bulbs have less lective white light, however they are considerably more expensive than other market options. More economic options are the Hella Optilux Extreme XY Yellow and the Narva All-Weather bulbs.

Selective Yellow Bulb Coating

If you would like to make your existing head light bulbs into selective yellow lights, you can buy a special coating that will limit the amount of emitted blue light. This is a cost-effective way to achieve similar results with your fog lights.

During the life of your Trailblazer, the bulbs in the headlight may burn out and need to be replaced. In order to replace these bulbs, the headlight assembly needs to be removed from the front of the vehicle. Removing the headlight assembly allows you to access the bulbs, which are connected to the sockets on the electrical connectors. Before starting this project, the bulbs will need to be purchased from an auto supply store.

Instructions

1

Open the drivers side door and pull the hood release lever to release the hood. Lift the hood up and set the support bar.

2

Find the snap clips that are used to secure the grill to the front of the vehicle. Pry the retainer clips with the flat head screwdriver to release them. Pull the grill off of the vehicle.

3

Find the retainer clip that is located in the upper left or right of the headlight. Push up on the retainer clip with the flat head screwdriver. Look under the fender, beneath the headlight, and locate the second retainer clip. Push this retainer clip up with the screwdriver.

4

Press the release tab that is on the back of the headlight assembly. Pull the electrical connector out of the headlight. Pull the headlight assembly out and set it on a bench or table.

5

Pull off the two rubber caps on the back of the headlight assembly to expose the headlight bulbs. Turn the socket counterclockwise and pull the bulb out of the headlight. Lift up the tab on the electrical harness and then pull the bulb out of the socket.

6

Insert a new bulb into the socket and then place the bulb back into the headlight. Turn the socket to the right or clockwise to lock it in place. Set the rubber caps back in place over the electrical connector.

7

Set the headlight back in place and then reconnect the electrical connector. Push the upper and lower retainer clips back in place to secure the headlight.

8

Set the grill back in place and then push on it firmly to secure the retainer clips to the frame.

The Hyundai Elantra GT is a Korean made car that is shipped all over the world. The fog lights that are mounted on the front of the car are 55-watt bulbs. Fog lights are used when visibility is low due to inclement weather. The Hyundai Elantra takes a 9006 style replacement bulb, which is a common and easy to find fog light.

Instructions

1

Raise up the front of your Hyundai using a jack to support it. Disconnect the wiring to the fog lights. The wiring is connected using a harness, so simply depress the locking tab and pull it off.

2

Turn the bulb in a counterclockwise direction until you feel or hear a click. This means that it has unlocked from the housing. Pull the fog light straight out.

3

Push the new bulb into the housing connector and then turn it in a clockwise direction.

4

Reconnect the wiring by clicking the harness back into place. Replace the foglight from the other side in the same way.

5

Lower the car and remove the jack from underneath.

The Chevrolet Cavalier might have been a pretty decent little car in itself, but a certain malady followed the name wherever it went. Not only was the Cavalier not quite the import-killer that GM had hoped; older buyers had never forgotten that it was essentially a rebadged relative to the worst rebadged travesty in history: the Cadillac Cimarron. The Cobalt that replaced the Cavalier, free of such burdensome history, rose quickly from its 2004 debut to become one of Americas favorite compact cars.

Dash Lights

The 2008 Cobalt, like most modern cars, used a few different dash bulbs. The basic bulbs were single, white LED units from Equus, part number 9903. Part number 9904 was three 9903 bulbs splined into the same harness. The 5-inch Autometer tachometer uses a white, twist-in bulb, part number 3219. The gauges also use a few Autometer-brand, colored LED bulbs: the green LED is part number 3283, the blue is number 3286 and the red LED number 3294.
