Hyundai Tucson: Maintenance / Light Bulbs

Consult an authorized HYUNDAI dealer to replace most vehicle light bulbs. It is difficult to replace vehicle light bulbs because other parts of the vehicle must be removed before you can get to the bulb. This is especially true for removing the headlight assembly to get to the bulb(s).

Removing/installing the headlight assembly may result in damage to the vehicle.


  • Prior to replacing a light bulb, depress the brake pedal, shift to P (Park), apply the parking brake, move the ignition switch to the LOCK/OFF position, and take the key with you when leaving the vehicle to avoid sudden movement of the vehicle and to prevent possible electric shock.
  • Be aware the bulbs may be hot and may burn your fingers.


Be sure to replace the burned-out bulb with one of the same wattage to prevent damage to the fuse or electrical wiring system.


To prevent damage, do not clean the headlight lens with chemical solvents or strong detergents.

Information - Headlight desiccant (if equipped)

This vehicle is equipped with desiccant to reduce fogging inside the headlight due to moisture. The desiccant is consumable and its performance may change based on the used period or environment. If fogging inside the headlight due to moisture continues for a long time, contact an authorized HYUNDAI dealer.


The headlight and tail light lenses could appear to have condensation inside if the vehicle is washed after driving or if the vehicle is driven in wet weather. This condition is caused by a higher temperature inside the light and a cooler outside temperature. Moisture that condenses in the light is removed after driving with the light on. If the moisture is not removed, contact an authorized HYUNDAI dealer.


  • A normally functioning light may flicker momentarily to stabilize the vehicle’s electrical control system. If the light goes out, or continues to flicker, contact an authorized HYUNDAI dealer.
  • The parking light may not turn on when the parking light switch is turned on, but the parking light and headlight switch may turn on when the headlamp switch is turned on. This may be caused by network failure or vehicle electrical control system malfunction. If this occurs, contact an authorized HYUNDAI dealer.


Adjust the headlight aim after an accident or the headlight is replaced.
