If the brake lights on a vehicle do not work on one side, this could be an indication of a blown bulb. Also, some vehicles have front lights that affect the rear lights, so checking for problems in the front lights could help as well.

Why left side brake light doesn't work when I step on the brake but works when the head light is on?
tail light bulbs has two filaments inside. One for regular lights and a second for brake lights. One filament is burnt out. Change the bulb.
How can you get your brake lights to work when you apply the brake?
The first thing that I would do is look at the arm of the brake pedal and make sure the arm is pressing against the brake switch, press the brake pedal with your hand and see if the switch head goes in. Also if you have someone with you have them watch the brake lights and use 2 fingers and press the head of the switch in and ask if the brake lights are on,it may be that the switch is bad. this would be step 1. depending on how old the vehicle is you may have a broken 12 volt wire or a ground wire, if your turn signals work and your taillights work I would first check the brake light switch. i have never seen 2 brake light bulbs go bad at the same time.
What is wrong if the tail lights work but one brake light doesn't when the lights are on?
There are two filaments in the lamp. One for the tail light and a brighter one for the brake light. First thing I would do is pull out the bulb and check the filaments to be sure that they are both good. If the lamp appears to be good you can have someone hold the brake pedal down and check for voltage.
Why would your lower brake lights not work when the upper brake light does work?
By the nature of the question I assume that you are referring to the tail lights and brake lights. My Explorer has four bulbs. Tail, brake turn and backup. They are all in separate compartments of the light assembly. So it could be that you have just burned out one bulb. If you are referring to the upper brake light in the rear window or at the top of the tailgate, same thing. One or more bulbs are burned out. I see people driving all the time with both lower lights burned out and the top working or visa versa.
On a 1994 ford ranger how does the brake light switchsending unit work?
The brake light switch is located near the top of the brake pedal. When the pedal is depressed the switch is activated and sends current to the brake lights. To access the switch, the under dash panel needs to be removed.

Check the brake light fuse. If you have 12 volts at the brake light switch I would suspect the signal light switch is at fault.

Usually that would be caused by a faulty brake light switch connected TO the brake pedal. If the brakes work the pedal is probably ok.
