Common Issues behind Nissan Altima Headlight Assembly Defects

Placed at the front of your Nissan Altima, the auto's headlight assembly is engineered not only for optimum lighting but also for improved resilience to external elements and extreme weather conditions. However, constant exposure to these unwanted elements can take its toll on the auto's headlights. This could soon cause all sorts of lighting and safety issues to your vehicle. If you think you have a faulty headlight assembly, then you had better perform some troubleshooting. Listed below are some common issues that are encountered with Nissan Altima headlight assemblies.

Flickering headlights

A possible reason behind flickering headlights is a failing charging system, or it could also be a faulty headlight assembly. You can easily diagnose this by taking a look at your car's fuse panel, which is located under the steering column. You see, frayed or damaged wirings may cause the headlights to flicker. Alternately, you can check the hood for damaged wiring that runs to the headlights. If this is not the case, then you may proceed to check the tension on the alternator belt. A defect in the alternator belt causes the car to run low in RPMs, which then causes the headlights to waver.

Yellow or cloudy headlights

If you have been recently experiencing a sudden decrease in the headlight's brilliance, but your lamps have just been recently replaced, then check the headlight cover for indications of fogging or moisture. This lamp defect is easy to detect because of the change of headlight color. You see, the moisture build up is caused by cracks or sealant loss. When the headlight housings are short of sealant, the condensation settles in and affects the lighting performance of your car. So be sure to check for any sealant issues and cracks when troubleshooting for headlight assembly problems.

Other troubleshooting tips

When replacing or inspecting your car's headlights, be sure to wear rubber gloves. In fact, failing to wear them causes the headlights to wear at an earlier rate. This is because the oil from the skin reacts to the bulbs' lighting system and will eventually increase the rate of the headlight's expiration.

  • Tips on How to Prevent a Cloudy Nissan Altima Headlight Assembly 04 March 2014

    Engineered to provide the optimum front lighting for your Nissan Altima, the headlight assembly is equipped in a durable housing for a longer life service. However, the headlight assembly will exhibit lighting issues overtime, and one of the biggest problems that you may encounter is cloudy headlights. To makes sure that your Nissan Altima's headlight assembly is in its peak condition, follow these tips and tricks to prevent condensation build up:

    • Know what to apply before installation
    • The most common cause of condensation build up is attributed to cracks in the lens' housings and sealant loss. You see, these defects are easily prevented by applying dielectric grease on the headlight socket. This simple addition inhibits moisture to settle in and decreases the possibility of corrosion. In addition, apply a silicon sealant along the headlights' frame because the sealers can sometimes melt or loosen during hot conditions.
    • Using a hair dryer and a lint free cloth
    • Every time you drive during cold weather conditions, you expose your headlight assembly to a large amount of condensation that may creep in inside the bulbs. So, it is advisable to detach your headlight casings once in a while and clean up using a lint free towel and a hair dryer. Removing the headlights allow the trapped moisture to air out. By constantly monitoring and cleaning regularly, you extend the headlight's life service and prevent moisture to settle in the headlight bulbs. However, be sure to always wear rubber gloves when removing the bulbs because contact to skin oil will reduce the headlight's life service.
    • Applying Teflon tape
    • As a maintenance tip, you can apply a Teflon tape around the headlight bulb socket to reinforce moisture prevention. You see, its application covers the gaps, cracks, or any openings within the headlight assembly. In addition, it prevents air from entering the assembly and turning into condensation.
    Other maintenance tipsIf water has already built up in your headlights, the easiest way to take it out is to drill a small hole at the bottom and applying a sealant afterwards. Even if the lenses are taken off and left to dry, condensation is likely to occur again unless a proper sealant is used or some of the parts are replaced.
