Quick Summary

The Mazda 3 tail light-also called the rear light, tail lamp, or rear combination lamp-keeps you visible from behind, shows braking, and signals turns. From the 2004 first-generation cars to the 2025 models, Mazda used a mix of halogen-bulb housings and newer full-LED assemblies. Bulb sizes (7443/W21-5W for many bulb-type years), fuse numbers, wiring, legal rules, common failures like condensation, and easy upgrades such as sequential LED sets are all well-documented. Keeping the lamp clean, checking fuses, and replacing worn gaskets extend its life and meet U.S. lighting law FMVSS 108. (Mazda Owners Manual, eCFR, NHTSA)

What It Does

Visibility & Signaling

A tail light lets drivers behind you see the Mazda 3 at night or in bad weather. When you tap the brake, a brighter filament or LED section flashes red so people know you're slowing down. (Mazda Owners Manual)

Parts Inside

Typical units combine:

  • Running-lamp filament or LED strip
  • Stop-lamp (brake) filament/LED
  • Rear side-marker reflector
  • Built-in gasket to keep water out

Key Features

Bulb vs. LED

  • 2004-2013 (BK & BL) - Halogen twin-filament 7443 bulbs are common. (Mazda Owners Manual)
  • 2014-2018 (BM/BN) - Split design: inner hatch lamp plus outer quarter-panel lamp; many trims switched to factory LEDs in higher packages. (YouTube)
  • 2019-2025 (BP) - Standard full-LED "signature wing" tail lamp that uses less power and lights faster. (AUXITO)

Styling Options

Clear lenses, smoked lenses, and sequential turn-signal LED kits fit the same mounts and wiring clip for 2014-2023 sedans and hatches. (Amazon, MIKSTOREPH LLC)

Bulb Guide

  • 7443 / W21-5W - Tail/stop bulb for 2004-2013 and some 2014-2018 halogen trims. (Mazda Owners Manual)
  • WY21W (amber) - Rear turn signal on bulb-type cars.
  • LED module - Non-serviceable on most 2019-2025 units; replace full assembly if an LED fails. (AUXITO)

Safety Rules

U.S. law FMVSS 108 says rear lamps must shine red, be visible 1,000 ft at night, and LEDs must meet the same brightness curve as filament bulbs. (eCFR) Amber stop lamps are not allowed on passenger cars. (eCFR)

Troubleshooting

  • No Light - Check fuse #35 (2004-2009) or #15 (interior dome fuse feeds tail circuit on some 2014-2018 cars). (Mazda3 Revolution, Mazda3 Revolution)
  • Condensation - A light mist inside lens is normal and should clear after a drive; heavy water means bad seal and requires replacement. (NHTSA, NHTSA)
  • Camera Recall Confusion - Some Mazda 3 recalls apply to rear-view cameras, not tail lights; verify with your VIN on Mazda's recall site. (Kbb.com, Mazda USA)

Replacement Steps

  1. Open trunk or hatch and peel back the carpet trim. (Mazda Owners Manual)
  2. Remove the three 8 mm nuts holding the lamp.
  3. Pull lamp straight back; unclip the wiring harness. (YouTube, YouTube)
  4. For bulb-type units, twist the socket counter-clockwise and swap the bulb.
  5. Reinstall and hand-tighten nuts to about 36-48 ft-lb per workshop threads. (Toronto Mazda 3, Reddit)

Upgrade Options

LED "sequential" rear lamps plug into the factory connector, add sweeping turn signals, and drop current draw by roughly 65 %. (Amazon, MIKSTOREPH LLC) Keeping the original harness means no dashboard error codes.

Care Tips

  • Wash lens with mild car-wash soap; avoid ammonia cleaners that dull plastics.
  • Once a year, wipe the gasket and add silicone grease to keep water out.
  • Replace cracked lenses quickly-water can short the rear light fuse. (Mazda3 Revolution)

Environmental Impact

Switching from halogen bulbs to LED modules saves about 7 W per lamp, lowering load on the alternator and trimming fuel use a tiny bit over time. (AUXITO)

Frequently Asked Questions

Q: How long should a Mazda 3 tail lamp last?
A: A halogen bulb often lasts 4-6 years; factory LEDs can exceed 10 years under normal use. (Mazda Owners Manual)

Q: Can I replace just the bulb on a 2020 Mazda 3?
A: No. The 2019-2025 LED assemblies are sealed; if one LED fails you replace the whole unit. (AUXITO)

Q: What size fuse controls the rear lights?
A: On most 2014-2018 cars it is a 10-amp mini fuse in slot 15; always match the original rating. (Mazda3 Revolution)

Q: Is condensation inside the lens a problem?
A: A light haze is normal and should clear after the light warms; pooled water means it's time to swap the lamp. (NHTSA)

Q: Are LED upgrades legal?
A: Yes, if they meet FMVSS 108 color and brightness rules and show DOT or SAE marks on the lens. (eCFR)

Q: Do tail lamps affect brake-light function?
A: Yes-on bulb units the same 7443 bulb has two filaments for running and brake lights. (Mazda Owners Manual)

Q: Will a 2016 lamp fit a 2014?
A: Yes, 2014-2018 outer lamps share the same mounting and connector. (YouTube)

Q: What tools do I need to remove the lamp?
A: A trim pry tool, 8 mm socket, and a Phillips screwdriver for inner trunk lamps. (YouTube)

Q: How bright must the light be?
A: U.S. law requires at least 80 cd for the tail function and 300 cd for the stop function measured at 0° test angle. (eCFR)

Q: Why did both rear lights go out together?
A: Start with the fuse or the light-switch stalk; both bulbs rarely fail at the same moment. (Mazda3 Revolution)
