Majdi, if you mean the brake warning light in the dash is on after starting your car, the light is telling you there is a fault/problem with the braking system. You should not continue to drive if the brake warning light is on, as your brakes could fail. You will have to have a good shop check your brakes and diagnose problem and estimate repair. Check the attached links,instruction and guides, Good luck

What Causes the Brake Warning Light to Come on
http://honda-tech.com/honda-accord-1990-2002-2/%22brake-lamp%22-light-went-meaning-problem-1723211

The brake lamp light simply means one of your brake lights is burned out and the battery light means your alternator is not producing the proper voltage and/or amps to correctly charge the battery.

Yes. The reason it looks like the lights on the rear of the car and the reason it comes on every time you are hitting your brakes, is because your lamp-out module is trying to tell you that you have a brake lamp that is not working. This is normal function if you ave a burned out bulb or a broken wire in your brake lamps. It does not set any codes, so there is nothing to "reset". Just fix the brake lamp and the warning lamp will go away.

Usaly the Red brake lamp means your brake system needs service, It will set when emergency brake is moved even the slightest, Or if the brake fluid level is to low. If it is low? Do not top it off, Inspect for leaks, And pad/shoe wear. if all is well then the mastercylender is bypassing and needs replaced

If you mean that the brake warning lamp on the dash board comes on when you press the brake, then its because the brake fluid level is low and/or the brake pads are worn down to the limit.
If you mean that the brake lamps at the rear of the vehicle comes on when you press the brake, then thats how it should work, to let other road users know you are stopping. Hope that helps

one of your brake lamps is out.

when the brake light is on it usualy means one of two things. First one is parking brake is on, second is low on brake fluid. More then likely time to change brake pads or could be leak in the system.

It could be low fluid, bad sensor or the e-brake could be on even just a bit
