99 HONDA ACCORD BRAKE LIGHT (DASH) KEEPS COMING ON

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

check the fron brake pad thickness ,it may be the front pads are worn and the sensor is touching the brake disk

I assume you mean the one on the dash. This is an indicator that there is a problem in your braking system. Make sure it's not low on Brake fluid and have the brake system checked or check it yourself. If your going to check it yourself I recommend the Haynes repair manual on your vehicle as a reference.

depending on actual model,honda state between 5-8 ltr for all there cars.....flash at 8,on solid at 5...

Brake light switch? Its mounted near the top of the brake pedal lever. The lever contacts and holds the switch closed which keeps the lights from turning on when at rest. When you step on the brake, the contact is broken, the switch extends and completes the circuit allowing the brake lights to illuminate.

usually when there is an interuption in current flow you will get flickering indicator lights on the dash. This means one of two things, either the sensors that control those indicator lights are becoming faulty or the alternator may be on its way out. One thing you need to keep in mind if you ABS unit is on its way out you will not notice any difference in drivability. ABS is just a brake assist(Antilock Brake System) when it fails you don't lose your brakes you just stop like a regular brake system would without an assist.(ABS) Maybe the unitis on its way out as well.. I would ge it checked as well.. Good Luck

You need an alternator.

The brakelamp could mean brake probs or brake light needs repairing for the door ajar it could mean that the censor in the door isn't reading properly. It could also be a short in the dash wiring.

This I believe is a daytime driving light indicator as it appears to only be on Canadian models
