Buy Hyundai Tucson Headlight Assembly

Hyundai Tucson headlights started as simple halogen head lamps and now shine with bright LED projectors that earn "A" scores for reach and glare control in 2024-2025 safety tests. A small 2022 recall shows how vital working front lights are: a software glitch could shut off both the head- and tail-lights on a few SUVs. Use this guide to learn which front-lamp assembly fits your year, what bulb type you need, how to aim the beams, and how to keep the lights legal, bright, and earth-friendly.

Overview

The headlight, also called a head lamp or front-lamp assembly, lets you see the road and lets others see you. It houses the low-beam and high-beam bulbs, wiring, fuse, and aiming screws. When even one part fails, night driving gets risky. IIHS tests show that better lamps can cut crash rates after dark.

Fit & Years

Bulb Types

• 2005-2015 low-beam: H7 halogen.
• 2005-2015 high-beam: 9005 (HB3) halogen.
• 2016-2021 projector trims: D8S HID or LED module (non-serviceable).
• 2022-2025 all trims: Integrated LED modules; no separate bulb changes.
  Always match the socket or module code in your owner's manual before ordering.

Technology

Modern Tucson lamps add:

• LED projectors that use less power and send light farther. IIHS found "good" or "acceptable" reach on every 2021-2025 test set.
• High-beam assist (auto-on high beams) on many trims from 2021 up.
• Auto-leveling motors on HID setups to keep glare down when the SUV is loaded. Owner's manual notes automatic self-check at start-up.

Common Problems

1. Condensation behind the lens. Small water mist is normal and clears as you drive; heavy pooling means a bad seal.
2. Fuse blowouts. Low-beam and high-beam fuses sit in the engine-bay box (check the lid diagram).
3. Mis-aimed beams. Many owners report factory aim set too low; a #2 Phillips screw behind the lamp lets you raise or lower it.
4. 2016-2018 wiring wear. Early TL harnesses can chafe near the radiator support, causing intermittent lights. Community fix notes extra loom wrap.

DIY Care

• Bulb swap (halogen) takes a 10-minute twist-and-pull from behind the housing. Wear gloves so oil from skin does not shorten bulb life.
• LED module replacement on 2022-2025 lamps requires whole lamp removal-four 10 mm bolts and a wiring plug. Check torque spec in the shop manual before reinstalling.
• Beam aiming: Park 25 ft (7.6 m) from a wall, mark lamp center, then turn the vertical screw until low-beam cutoff sits at or just below the mark.
  A correct beam keeps oncoming drivers safe and meets the 22-inch minimum center height rule in federal code.

Safety Rules

• U.S. Federal Motor Vehicle Safety Standard (FMVSS) 108 sets photometry, color, and durability rules for all replacement lamp assemblies.
• Europe and many export markets follow UN Regulation 112 for LED and halogen beam patterns and UN R48 for aim and auto-leveling.
• Always keep both lamps working; NHTSA can recall vehicles when software kills lamp output, as it did for a handful of 2022 Tucsons.

Upgrades

• LED retrofit bulbs (for 2005-2015 reflector housings) can deepen night vision, but be sure they have a focused emitter and DOT compliance pouch so light does not scatter.
• Projector swaps give a sharp cutoff and wider spread; quality hinge mounts ease alignment.
• Any upgrade must not exceed 2,000 lumens per bulb or the lamp ceases to self-certify under FMVSS 108.

Environment

Halogen and HID bulbs contain glass and small metal parts; fluorescents and HID capsules also carry mercury. The U.S. EPA calls used lamps "universal waste" and urges drop-off at local hazardous-waste centers. LEDs lack mercury but include solder with trace lead; recycling saves valuable metals and keeps toxins out of landfills. Wrap any broken glass in paper before disposal and label the package "waste lamp."

Frequently Asked Questions

Q: What headlight bulb size fits a 2019 Tucson?
A: Low beam is H7; high beam is 9005 (HB3).

Q: Why do my 2023 Tucson lights seem too low at night?
A: Factory aim can sit low to avoid glare. Raise the vertical adjuster screw behind the lamp until the beam cutoff is just under headlight center at 25 ft.

Q: Are LED modules serviceable on 2022-2025 lamps?
A: No. If an LED fails, you must replace the whole front-lamp assembly because the diode board is sealed inside.

Q: Is it legal to tint or smoke my head-lamp lens?
A: Dark films reduce light output and can violate FMVSS 108 or local laws that demand white or amber forward lighting.

Q: How can I stop moisture inside the lens?
A: Light mist clears on its own. Heavy water means a leak; remove the lamp, dry it, and reseal the rear cap or lens seam with automotive-grade butyl.

Q: My head-lamps quit and the fuse is fine-what else?
A: A known software bug on some 2022 SUVs can shut off lamps; Hyundai issued a recall to reprogram the control unit.

Q: What is the head-lamp fuse number on a 2018 Tucson?
A: Engine-bay fuse box position F14 protects both low beams.

Q: Do brighter bulbs improve safety?
A: IIHS data show higher-rated lamps lower crash risk at night, but beam focus and proper aim matter more than raw brightness.

Q: How do I dispose of an old HID capsule?
A: Treat it as hazardous waste; store it in a sealed box and take it to a collection site that handles mercury bulbs.

By understanding bulb sizes, rules, and care, you can keep every Hyundai Tucson head-light-whether halogen, HID, or LED-shining safely and legally for years to come.
