The brake lights on a 2019 Hyundai Tucson are located at the rear: two main brake lights in the left and right taillight assemblies, and a center high-mounted brake light at the top edge of the rear window on the tailgate.
When you apply the brakes, the left and right taillights illuminate, and the center high-mounted brake light (CHMSL) also lights up to improve visibility for drivers behind you. The exact appearance can vary slightly by trim, with some models using LED elements and others using traditional bulbs.
Brake light layout on the 2019 Tucson
Below is a quick breakdown of where each brake light is located and what you should expect to see when braking.
- Left rear taillight brake light: located in the left taillight cluster at the outer left rear corner; illuminates when braking (and also serves the left turn signal when used).
- Right rear taillight brake light: located in the right taillight cluster at the outer right rear corner; illuminates when braking (and also serves the right turn signal when used).
- Center high-mounted brake light (CHMSL): mounted at the top edge of the rear window on the tailgate; provides a third, higher brake signal to following drivers.
In short, braking in a 2019 Tucson typically triggers three lights: two in the tail light assemblies and a CHMSL perched above the rear window.
Center high-mounted brake light (CHMSL) specifics
On the 2019 Tucson, the CHMSL is usually a slim light mounted along the top of the rear window or integrated into the tailgate’s upper trim/spoiler area. It serves as a supplementary brake signal to improve visibility, especially in heavy traffic or mountainous driving conditions. If the CHMSL isn’t lighting when you brake, it may indicate a bulb/LED failure or a blown fuse, and should be inspected by a technician.
What to do if a brake light isn’t working
If you notice a brake light out, use this checklist to diagnose the issue before seeking service.
- Check the bulbs: Inspect the left and right taillight bulbs and the CHMSL for burnt filaments or failed LEDs; replace as needed.
- Check fuses: Find the brake light fuse (the label may read BRK or LT BRK) in the vehicle’s fuse box and replace a blown fuse.
- Inspect wiring and connectors: Look behind the taillights and CHMSL for loose connections, corrosion, or damaged wiring, especially after cargo loading or car washes.
- Test systematically: Have someone press the brake pedal while you observe each light to confirm which one is not functioning; if more than one light is out, the issue may be a common ground or power supply fault.
If you’re unsure or the problem persists, consult a Hyundai dealer or a qualified mechanic to restore full brake-light function and safety.
Summary
A 2019 Hyundai Tucson uses two main brake lights in the left and right taillight assemblies plus a center high-mounted brake light at the top of the rear window. Braking activates all three signals for maximum visibility. If any light isn’t working, check bulbs, fuses, and wiring, and seek professional repair if needed.
