A US mechanic called Eric has issued a warning about aftermarket LED bulbs after discovering what happened to his daughter’s car.

He opened the tailgate of her Honda Element and found the brake lights completely dead.

The cause, he says, was a pair of LED replacements that failed without warning.

He has now made the drastic decision to stop using aftermarket LEDs on any of his vehicles.

Aftermarket LED bulbs caused issues with his daughter’s car

A US-based car mechanic shared a big discovery in a video about his daughter’s Honda Element.

He pulled failed bulbs out of the car’s brake lights and explained why he no longer trusts them.

He said they did not fade or flicker but simply just stopped working, leaving the car with absolutely no brake lights.

He added that regular filament bulbs usually show clearer signs of trouble and are easier to anticipate when they conk out.

The mechanic also said this issue happens more often than people expect, and many modern cars use a body control module to monitor LED bulb health.

Because LEDs draw so little power, the system can misread the signal and assume a bulb has burned out, and then this can trigger warning messages or cause electrical quirks in your car.

Why LED conversions can create electrical issues

Aftermarket LEDs also cause heat and quality concerns, and cheaper bulbs often lack proper heat control and can fail early inside the headlights.

Compatibility adds to the problem because many cars are not designed to work with LED replacements unless resistors or adapters are installed.

Without them, the low power draw can cause flashing, error codes, or lights that don’t operate correctly.

Some drivers have even reported the battery draining or interference after installing budget LEDs.

Eric said switching back to simple filament bulbs is worth it for reliability, and he suggested that drivers think carefully before swapping factory bulbs for aftermarket LEDs, especially in safety-critical areas like brake lights.
