Bad bulbs: If the bulbs are old or of poor quality, they may be more likely to blow. Check the bulbs and replace them if necessary with high-quality bulbs rated for the correct voltage.
Loose or corroded connections: Check all the electrical connections in the brake and tail light circuits for looseness or corrosion. Clean any dirty or corroded connections and make sure they are tight, ensuring a proper electrical connection.
Malfunctioning switch: The brake light switch, which is responsible for turning on the brake lights when you press the pedal, may be malfunctioning. Test the switch and replace it if necessary.
Faulty wiring: Damaged or faulty wiring can cause short circuits and overheating, leading to blown fuses or bulbs. Inspect the wiring for damage and replace any damaged or faulty wiring.
Overloading: If you have added additional lights or accessories to your vehicle that draw excessive power, it may be overloading the electrical system and causing the fuses to blow. Check the electrical system to make sure it can handle the additional load.
Grounding issues: A bad ground connection can cause various electrical problems, including blown lights. Ensure that the ground connections in the tail and brake light circuits are clean, tight, and making proper contact.
Damaged tail or brake light housing: If the tail or brake light housing is damaged, it may allow moisture and debris to enter the housing, causing the bulbs to blow. Check the housing for damage and replace it if necessary.
