Brake light flickers while driving down the road.

It is NOT SAFE to drive your vehicle when the BRAKE and ABS lights are illuminated simultaneously.
I recommend that you have the vehicle TOWED to a repair facility for inspection, as you may find yourself with NO BRAKES, and UNABLE TO STOP.

Was any of the brake light bulbs changed recently, the wrong type of bulb may be used causing a short in the socket, and making the rest of the brake and signal circuit malfunction. I no bulbs were recently replaced, start with checking for corrosion in each bulb socket, signal and brake bulb sockets. Let us know what you find

Brake light indicater indicates low brake fluid or loss of brake control. Check fluid level.

Did you reseat the pads and calipers by pressing the brake pedal several times after completing the job?

Have you driven it at all? Do the brakes seem to be working properly other than the light?

there is a bad speed sensor on one of the hubs. i wouild take it to a respectable garage with a diagnostic scanner to tell you wich one is bad,also for the brake light check the brake fluid bottle and see if its low

check turn signal switch, the brake signal goes through the switch

if the brake lights work but are not very bright means they are not getting the full amount of voltage to them. the circuit board in the tailight could be bad or corroded not letting power get through also could be in the brake light switch.

you must check the layout first if the layout is ok then trace from the dash boards connection and you will know what wrong with the dash board lighting system,.after that contact your auto eletrician to re-connect the wires in the dash board.thank you

sounds like it is a brake light switch located at the brake peddle. test the switch and if it is faulty replace it.

Hitting the emergency brake's has nothing to with the brake lights on the back of the vehicle , you had to have this problem before an just didn't notice . Are all the brake lights lit ? High mount lamps too.. ? The regular one's are controlled by a BCM - body computer .
