are jeep commander light sockets ck polarity

Jeep Commanders use CK-style sockets for their front turn signal lights. CK sockets are different from standard sockets in that they have a different wiring configuration, with the ground contact at the top and the high and low circuits below. This is different from standard sockets, which have both grounds on the left side of the socket. It's important to know which type of socket your car has before upgrading your light bulbs, as using the wrong type of LED bulb can cause them to not work properly or blow your fuses.


How to identify your Jeep Commander's light socket type

To identify the light socket type of your Jeep Commander, you can follow these steps:

Step 1: Search online

Start by searching Google or YouTube to see what other Jeep Commander owners are using. You can try searching the make, year, and model of your car along with the phrase "CK or standard socket." For example, if you have a 2006 Jeep Commander, you can search for "2006 Jeep Commander CK or standard socket." This will help you determine if your vehicle uses a CK or standard socket configuration.

Step 2: Visually inspect the socket

If you're unable to find the information you need through online searches, the next step is to visually inspect the socket on your Jeep Commander. Remove the taillight socket and take a closer look inside. Orient the socket so that it matches images or diagrams of standard and CK sockets. Standard sockets have both grounds on the left side of the socket, while CK sockets have the ground on the top and the high and low circuits below.

Step 3: Test with a multimeter

If you still can't determine the socket style or if it's difficult to visually inspect, you can use a multimeter to test the positions of the grounds. This will help you confirm whether your Jeep Commander has a CK or standard socket.

It's important to identify the correct socket type before purchasing LED bulbs or making any modifications to your vehicle's lighting system. Using the wrong type of LED bulb can lead to improper functioning or blown fuses.

How to test your light socket with a multimeter

If you're experiencing issues with your Jeep Commander's light sockets, you can test them with a multimeter. Here's a step-by-step guide on how to do it:

Step 1: Voltage Test

  • Set your multimeter to measure AC voltage in the 200-volt range.
  • Set the black lead into the common port (COM) and the red lead into the mAVΩ port.
  • Remove the bulb and turn on the power.
  • Hold either lead on the metal socket casing.
  • Touch the bulb at the bottom of the socket with the other lead.
  • If the reading is close to 120 volts, the socket is functioning correctly. If it's significantly lower or zero, the socket is faulty.

Step 2: Continuity Test

  • Set your multimeter to measure resistance.
  • Disconnect the fixture from the power supply.
  • Touch one lead to the ground screw or ground wire on the disconnected fixture.
  • Touch the other lead to either the socket itself or the bulb at the bottom of the socket. It's best to do separate tests for the socket and the bulb.
  • If the meter reads close to 0, the fixture is good. If it jumps to the right or reads "OL", the fixture is faulty.

Additional Troubleshooting:

If your tests indicate that the socket is functioning correctly but the bulb still won't light, try the following:

  • Replace the bulb with a new one to ensure it's not a bulb issue.
  • Check for corroded terminals. If they are corroded, clean them with isopropyl alcohol and a rag or toothbrush. You can also use sandpaper for stubborn rust.


How to upgrade your light bulbs to LED

Upgrading your light bulbs to LED can be a great way to improve your lighting, whether it's for your home or your car. Here's a detailed guide on how to upgrade your light bulbs to LED:

Upgrading Your Car Lights to LED:

  • Identify your car's socket type: Before upgrading to LED, it's crucial to determine whether your car uses a Standard or CK socket. The position of the ground contacts in the socket is the key difference. Externally, they look identical. You can search online or on YouTube to see what other owners of your vehicle are using. Alternatively, you can visually inspect the socket by removing the taillight socket and checking the position of the grounds.
  • Choose the right LED bulbs: When purchasing LED bulbs, ensure they are compatible with your car's socket type. Some cars have reversed polarity electrical connections, so you may need polarity-free LED bulbs. Also, be aware that LED bulbs may be coloured red or amber, even if they are replacing clear incandescent bulbs.
  • Make a list of required bulbs: Identify how many bulbs of each size you need. You can find the industry standard numbers for each bulb type on websites like Sylvania or Philips auto bulb sites, or in the auto parts section of Amazon.
  • Install the LED bulbs: The installation process is similar to replacing a bulb with another incandescent bulb. Remove the old bulb, taking note of the bulb type and ensuring you don't touch the new LED with your bare fingers. Then, install the LED bulb and secure it by twisting it in the socket.
  • Handle "hyperflash": If your car's turn signals or hazard lights flash quickly after installing LED bulbs, it's a phenomenon called "hyperflash". This occurs because LED bulbs draw less power, and your car senses it as a blown incandescent. To fix this, buy an LED bulb resistor kit and clip one resistor to the wiring at each bulb location to increase power consumption.

Upgrading Your Home Lights to LED:

  • Start with frequently used lights: Begin by replacing lights in heavily trafficked areas or hard-to-reach places. For example, the living room or dining room tend to use more light and can benefit from the energy savings of LED bulbs.
  • Replace lights in sets: When replacing incandescent bulbs, consider replacing fixtures with multiple lights all at once to maintain even colour temperatures and light intensities. This is because incandescent bulbs warm in colour temperature and dim over time, so replacing them individually with LEDs may result in noticeable differences.
  • Consider dimmer compatibility: LEDs use a different dimming method than traditional incandescents. If you have dimmer switches, check for compatible LEDs or upgrade your dimmer switches accordingly.
  • Take before and after photos: To truly appreciate the difference, take photos of your current lighting setup before installing LED bulbs. This will help you visually compare the improvement in brightness and colour temperature.


How to avoid blowing your fuses when changing light bulbs

Changing a lightbulb in a Jeep Commander can be a tricky process, and it's important to take precautions to avoid blowing your fuses. Here are some detailed instructions to help you get the job done safely and effectively:

Identify the Correct Socket Type

Before you start, it's crucial to determine whether your Jeep Commander uses a Standard or CK socket. While they may look identical from the outside, the position of the ground contacts inside the socket is different. The wrong type of LED bulb can lead to malfunction or blown fuses. To identify the socket type, you can search online forums or inspect the socket by removing the taillight and observing the position of the grounds.

Choose High-Quality Bulbs

When purchasing replacement bulbs, avoid cheap options. Cheap bulbs have thinner elements that are more susceptible to power surges, leading to frequent blowing. Invest in higher-quality bulbs to save money in the long run.

Ensure Secure Connections

Loose connections in the lamp holder or bulb holder can cause electricity to "arc" or jump across the contact, generating excessive heat and potentially blowing the bulb. Check the connections inside your bulb holder and ensure the spring-loaded connection is secure. Look for pitting (tiny indentations) on the contact point of the bulb as a sign of arcing.

Be Mindful of Heat Sensitivity

LED bulbs are extremely sensitive to heat. Even a small amount of heat buildup can cause them to blow. Ensure that the bulb you're using is the correct size for its surroundings to prevent overheating.

Handle Polarity Sensitivity

Some LED bulbs are polarity-sensitive. If the LED doesn't light up after inserting, remove it, flip it in the opposite direction, and reinstall. This is a simple fix that can prevent potential issues.

Consult a Professional

If you're unsure or uncomfortable with any part of the process, don't hesitate to consult a qualified electrician. They can help identify any issues with your lighting circuit and ensure a safe and proper installation.
