Hand Brake Warning Lamp Does Not Turn On

Hello Friends, I have been driving a Peugeot 207 2009 model semi-automatic vehicle for 4 months.As I said, I have been riding for 4 months, but yesterday I noticed that the brake warning lamp does not light on the instrument panel when the handbrake is on, I wonder if the light bulb is on, but when the vehicle is in semi-ignition, all the lamps are on when the brake warning is on and then goes off. I learned that it may be related to the handbrake sensor. Could it be due to another problem or if I can get this part I can replace it myself. I want to do it cheaply. I wish you good days.

hello i don't think there could be anything other than handbrake sensor. If you have dexterity, it should be right under the handbrake lever.
