Brake lights work but not the taillights

Since these are on separate circuits first check the front park lights and dash lights are going since these ARE on the same circuit. If not check the fuse. If that's ok, remove taillight bulbs and check they are not blown. You should be able to see the filaments between the prongs inside the bulbs. If they are ok with a test light check there is power going to lamp sockets with light switch on. If they are dual filament bulbs only one contact inside the light socket will have power going to it. The other contact is the brake light. You will need to identify it by getting someone to work the brake while you hold the test lamp on either contact with the light switch off then the other one is the taillight contact.

Fog light on mk5 astra sxi not working on passenger side new bulb and checked fuse and fuse ok ?

With everything checking out OK, fuse, bulb, etc, and the driver's side is working, the problem may be the socket or the contacts. Check all wiring for that side, including ground wire. Giggle the wires going into the light to see if the works.

Rear lights not working

You will have to check the circuit boards for power. Check fuses for parking lights too

Tail lights don't work, but brake, flash and hazzard work.

generally when the fuse is ok and the bulb is ok the problem is corrosion of the ground wire and connection to the frame, or corrosion in the bulb sockets. for starters go to any auto parts store and get an aerosol can of contact cleaner especially for auto bulbs and connections.

The boot light will not work even with a new bulb

Fast solution:
Assuming all fuses are OK.
Check the filaments (look for a broken filament wire) in the old bulb to make sure it's a bulb problem. If the old bulb is truely defective, check the new bulb to make sure it does not have a broken filament. If the bulb looks OK, take a look at the socket to make sure that it is not rusty or corroded. If the socket contacts are not clean, take a small piece of fine sandpaper and clean both the center contact and the inside of the socket.
If you have tried these things, and the light still does not come on, you'll have to do a continuity trace of the wiring to fine where the power to the bulb is being interrupted.

Brake lights do not work All bulbs have been replaced.

Troubleshooting Procedures - Read Completely Before Beginning
(American Car) All Brake Lights Not Working
  • Check System Fuse: A fuse is used to protect the brake light circuit from amperage overload. If the fuse has failed it will not allow the electrical current to continue to the brake lights. To check the fuse, first locate the brake light system fuse in the fuse panel which is either under the dash or under the hood in the power distribution center. Connect the test light to a ground like an engine or dash bracket and turn the ignition key to the "on" position. Using the test light probe both sides of the fuse. If the test light illuminates on both sides the fuse is ok continue onto the next step. If one side of the fuse illuminates the fuse has failed and needs to be replaced. If the fuse fails as soon as it is replaced or when you apply the brake pedal the brake light electrical circuit is shorted to ground. Rarely a system short can occur, a car repair manual is needed to find the wiring schematic for the brake light circuit. Once the brake light wiring has been located inspect and repair as needed.
  • Check Brake Light Bulbs: All cars have three brake light bulbs that create the brake light illumination affect. If all of these brake light bulbs fail no brake light operation will occur. I know what you're thinking, you might say all three brake lights at once? But in reality one brake light went out at a time and you did not notice. People only tend to notice something when they almost run into the back of your car to help persuade them to inform you the brake lights aren't working. Remove any of the brake light bulbs to confirm the bulb is ok or burned. After the bulb has been removed inspect the filament and replace if failed. If the brake light bulbs are ok continue to the next step.
  • Checking the Brake Light Switch: A control switch is used to connect the brake light electrical circuit. This switch is located near the brake pedal lever. Basic switches have just two wires, power in and power out to the turn signal switch. Use a test light that is grounded and with the key in the "on" position test for power at one side (wire) of the switch, then press the brake pedal while testing the opposite side (wire). It should illuminate the test light, if electrical power is connected through the switch go to the next step. If no power is detected through the switch the brake light switch has failed and replacement is required. If your car is equipped with more than two wires integrated into the brake light switch a car repair manual is needed to locate the proper brake light circuit wiring.

Have you checked the bulbs and contacts ? To check the contacts, remove the bulb and check if it is not burnt out. Then get a voltage check tool. It is a tool that has an aligator tip on one end which you connect to ground. Then touch the pointed tip to the contact inside the bulb holder.A small light will glow in the tool itself if there is power.If it does not and it is not the bulbs then you have an open circuit somewhere. Cut wires, or even the switch itself may be at fault. contacts tend to flatten out and will not make good contact with the bulb.
