Please learn sentence structure and punctuation. You should have gotten the critical parts before you hit fifth grade.

Have you verified that the bulbs aren't burned-out? Do you have power to the bulbs when the brake pedal is pushed? If not, verify fuses, then trace wiring back until you do have power in the circuit.

Likely means air in the front or rear hydraulic system, including the anti-lock mechanism. I would flush the brake fluid until it ran clear and new at all four wheel cylinders, and also at the ABS valve unit if it has bleeder screw(s).

Constant, or only when you press the pedal?
Constant = defective brake booster
