Infiniti I30 Side Marker Lights

Diagnosing Common Problems of Infiniti I30 Side Marker Lights

The side marker lights are just one of many external lights of the Infiniti I30, and while they may not be as important in function as the headlights, a broken side marker light can make your vehicle less visible at night and in similar low-light conditions. Infiniti I30 side marker light problems come in many different forms, and troubleshooting them is necessary in order to determine the exact source of the problem and save you time and headaches getting it fixed. In this guide, we'll share some of the common problems of the side marker lights and how to diagnose them.

The side marker lights won't turn on

If the side marker lights won't light up even when the tail lights are switched on, it could indicate various problems ranging broken electrical connections to a busted light bulb. First, check if the wirings connected to the back of the side marker lights are frayed or cut and if the socket where the bulb is mounted is corroded. Next, check the bulb itself to see if the filament is burnt out. However, if both the side marker lights in your vehicle refuse to turn on, the problem might be with the fuse.

The lights remain on even when the tail lights are off

On the other hand, if the side marker lights do turn on but remain so even when the tail lights are already off, the switch for the light might be malfunctioning or out of sync. Moisture and corrosion can also cause the switch to fail and for the light to get stuck at the on position. Check the condition of the switch and adjust or replace it if necessary.

The light is dim

If you notice that the side marker lights are fainter than usual, there might not be enough power reaching the bulb. Turn on the ignition and check the charging voltage with a voltmeter. If the side marker lights are receiving enough power, the meter should display 13.5 to 14.5 volts. But if the meter reads anything less than 13 volts, there isn't enough voltage reaching the side marker lights due to a malfunctioning alternator or battery.

  • Maintenance Guidelines for Infiniti I30 Side Marker Lights

    Due to its location and relatively minor function compared to tail lights, the side marker lights are often overlooked by Infiniti I30 owners when it comes to maintenance. But just like the tail lights of the I30, the side marker lights are just as vulnerable to wear and damage and will break down if not properly maintained. What's more, caring for Infiniti I30 side marker lights are not that difficult and only require an hour or two of your time. The following are just some of the key maintenance tips we recommend you follow to ensure the long, reliable service of your car's side marker lights.

    Clean the side marker lights regularly to keep them from fogging up.

    Side marker lights tend to become hazy and lose their brightness over time due to dust and grime. In addition, constant exposure to ultraviolet radiation from the sun's rays can also degrade the lens, resulting with a milky film on the lensexterior. Ordinary car shampoo can be used to clean and restore the appearance of the side marker lens, while mild abrasive polishing cream can be used to eliminate haze and scratches on the surface of the lens.

    Check for and remove any excessive moisture from the inside of the side marker light.

    Due to differences in temperature inside and outside the side marker light housing (particularly at night), condensation may form as tiny droplets inside the lens. If not removed, this may cause the side marker light socket to become corroded and for the bulb to short out. To remove this excess moisture, drill 1/8 to 1/4 inch holes at the top of the side marker light housing and let sunlight shine directly on it. After a couple of hours (or an entire day depending on how much moisture is inside the housing) the lens will eventually clear up. Once the condensation is gone, close the hole you've drilled earlier with silicone glue.

    Inspect the lights regularly.

    Some of the things you need to look out for include cracks on the lens surface, frayed or cut electrical wires, and rust on the socket and other metal parts of the side marker light. If the light is severely damaged, have it replaced immediately.
