Im upgrading my brake light bulbs to LED 7443 bulbs and when I press on the brake pedal without keys in the ignition, theres a beep inside for the duration I hold the brake pedal. Is that some sort of warning that the car thinks the brake bulbs are out since theyre LEDs? If so, will i need to install a resistor for each of the bulbs? FYI, both brake filaments work just fine.
