my peugoeut 206 brake lights come on as soon as i turn on the ignition


You need to test the "BOO" switch that controls the brake lights, it is located above the brake pedal and the brake pedal arm opens and closes the switch. It of course should be an open circuit with 12 volts at one contact without the application of the brake pedal and a closed circuit with the pedal pressed down (12 volts in and out), Adjust or replace the switch as the testing dictates.

My 2004 Chevy malibu brake lights only come on if at complete stop


Your brake pedal has a switch mounted in conjunction with it. It's located above the pedal, under the dash on a bracket. The switch has a threaded collar on it and can be adjusted by loosing the 2 lock nuts.
The switch is deactivated when plunger is depressed ( opposite from a traditional switch)
When you step on the brake pedal the plunger is released (rasied) and the circuit is energized.
If your switch is out of adjustment the plunger will not fully rise during light braking, causing the brake light failure.

break lights dont work, I replace the lights how do you replace the break fuse what should I look for?


Bulbs are just like a fuse to for they blow out like a fuse. You have a brake light switch mounted near the brake pedal. Check that switch out with a OHM meter. Just unplug the switch and feed the Ohm meters contacts into the switch. Then push the brake pedal down to see if it completes the circuit. If a OL reading is showing at all times the switch is bad and needs to be replaced

No brake lights when depressing the brake pedal


This can be caused by a number of things. You just have to eliminate each one.
Light Globe Replace one with a new one if it works replace both.
Fuse Check fuse in fuse panel under bonnet.
Brake pedal switch Unclip wire connector, check with circuit volt light indicator, Ohm meter or other continuity tester.
Wiring from pedal switch to light globe As above (maybe cut squashed or broken wiring)
Hope this helps
