Wiring the New Lights

Connecting the new lights to the power source of your Wrangler might seem a bit tricky but it is not rocket science. Here is how you can perfectly wire the lights without causing any mishaps!

 

  • Check out the wiring in your jeep and also identify the wires that need to be connected from the new light to the connections of your jeep.
  • The efficient ways to wire the lights are by referring to the manual of the vehicle or getting a wiring diagram for the Wrangler JL JT jeep before starting the process.
  • Usually, the chassis of the jeep needs to be connected with the ground wire and the positive wire has to be connected to the corresponding wires in your jeep. Note: Do check the model of the vehicle beforehand to avoid any problems.
  • Use electrical tape to secure the wiring in place and help prevent any possible damage to the wiring. Electrical tape also keeps the wire secured and prevents it from getting loose.
  • You need to use a wire stripper to get rid of any extra insulation from the wires and guarantee a secure and successful connection.

How do you install the New Lights?

Installing the new turn signal lights and side marker lights is the final step in the process. Start by positioning the lights in place and securing them with screws or clips. Be sure to align the lights properly and make any necessary adjustments before tightening them down.

To ensure a secure installation that will last, we recommend double-checking the alignment and tightening the screws or clips firmly. You can also use a sealant or silicone to create a watertight seal around the lights and prevent any water from getting inside.

Testing the Lights

So far so good, good job at installing those lights. Now you need to test them. Here is how you can successfully check the lights and ensure that they are working perfectly!

  1. Start the vehicle and check each light individually. Light each of them one at a time and maintain a checklist of each light.
  2. Double-check that the turn lights are flashing perfectly and the side marker lights are also illuminating.
  3. If the lights are not operating correctly then there can be two reasons:
  • Problem with the wiring or connection.
  • The lights may have a fault or problem.
  1. You may use a multimeter to check the issue and identify any loose ends in the wiring.
  2. If you are still unable to identify the problem or solve the issue then it is better to consult an expert rather than experimenting and escalating the issue even more.

Here are some tips that can help you avoid major problems during the installation process and any other associated procedures. Let’s shed some light on them!

  • Always acquire the vehicle’s manual or wire diagram in advance to execute the process flawlessly.
  • Procure the right tools for the job e.g. pliers, screwdrivers, wire strippers, etc.

  • Never try to hurry any process or do a speedy installation process. You might skip some crucial steps or connect the wires in the wrong sequence.
  • Get LED lights as they are more efficient in terms of power consumption and they are more long-lasting compared to incandescent bulbs.
