This article applies to the Jeep Wrangler JK (2007-Present).

The HID headlights stand for high-intensity discharge. It’s a wise choice to brighten up the road ahead of you while driving, but if you do any type of off-roading at night, this should be a must. The last thing you want is to fall in a ditch or get stuck in the middle of the night. The HID lights increase the light your headlight produces tremendously. These bulbs are designed to last 2,000 to 3,000 hours; that’s a lot more than halogen lights, all while using less energy. If you want to take your Jeep Wrangler to the next level, HID headlights are the way to do it. Read this guide to learn how to install the kits yourself, but continue reading to learn all about the different brands and what’s right for you and your budget.

How to Install HID Headlights

Materials Needed

  • 10mm wrench
  • Flat head scewdriver
  • Torx screwdriver
  • Socket set
  • Industrial strength Velcro
  • HID kit

Step 1 – Disconnect battery and remove grille

The first thing you always want to do when doing any electrical work is to disconnect the battery. Using your 10mm wrench, disconnect the negative (black) battery terminal, then wrap it in a towel so it doesn’t touch any metal while you’re working.

Remove the grille. It’s held in place by six clips, stick your flat head screwdriver under it and pry it up, then pull it out completely. Tilt the grille back and reach from the side to disconnect the turn signals connected to it. Turn the turn signal’s electrical harness down to disconnect, then pull it back and out. Remove the grille.

Step 2 – Remove horn, air box, and move power steering reservoir

The horn is held in place by one Torx screw on the front of the engine, on the driver’s side.

Remove the air box. Loosen the clamp on the air intake hose going into the air box, unclip the clips on the air box cover, remove the cover, remove the filter, and finally remove the air box out. You will need to wiggle it a bit so it comes off of its three rubber grommets.

Use your 10mm socket to disconnect the power steering bolt, and then place it on the passenger’s side of the engine compartment; don’t disconnect the hoses.

Step 3 – Replace headlight bulb

Remove the stock, halogen bulbs by turning them counterclockwise, then pull them straight out. Install the new HID ones by turning them clockwise until they lock in place.

Step 4 – Install the ballast

Install the ballast underneath the headlights on the front of the Jeep. You can use heavy duty double tape or industrial strength Velcro to keep it in place.

Figure 7. Mount the ballasts on both sides, under both headlight.

Step 5 – Route the wires

Install the relay control module anywhere you want; a common place is between the passenger’s side front fender and the body. Route the wires into the engine compartment.

Route the red wire with the ring connector to the positive battery terminal on the battery. You can run it along the fender next to the factory wiring harness.

The passenger’s side ground wire can be connected to an existing body ground. The passenger’s side ballast’s connector will run to the passenger’s side ballast.

The rest of the wiring will go to the driver’s side headlight. You can run it along the factory wiring across the radiator.

  • Connect the ballasts connectors to each of their ballasts.
  • The ground wires to the body grounds on both sides.
  • The high/low beam connectors to both headlights.
  • Connect the red cable to the positive battery terminal.

Step 6 – Re-install parts

Installation is the reverse of removal.

  • Install the horn.
  • Install the power steering reservoir.
  • Reinstall the air box, air filter, and attach the air intake hose.
  • Reinstall grille and turn signal.

Kit Includes – Everything

Warranty – 1 Year

This light weight kit is designed to sneakingly install to your Wrangler, and publicly shine the whole road in front of it. This kit comes backed with a one year warranty. It can be sold as a single lamp or a whole kit, which includes the wiring harness you need for the swap, the adjustable mounting bracket, clear protective shield, and all the mounting instructions you need to get the job done. A lot of customers complained that the adjustable brackets don’t work well, since one click down makes it too low, so it’s not a proper selling point. Other customers claimed this brand is very bright, but it doesn’t last as long as the company claims; hence, the one year warranty. Many Jeep owners love the beam pattern on this kit, claiming that it adds a good amount of brightness over the stock, while providing a nice pattern that lights up the road.

Kit Includes – Everything

Warranty – 1 Year Bulb/5 Years Material

When it comes to easy installation, this kit takes the lead. It comes with everything you need to swap the factory halogen with the new HID kit. This product comes with a one year warranty on the bulb, but it also has a five year warranty on the rest of the material and wiring; so if you take your Jeep off-roading and expose it to hard conditions, this warranty might come in handy. Even though this kit could get quite pricey, it makes up for it with quality. Delta takes pride in their materials and parts. The kit comes equipped with everything you need to install it, in addition to rubber boots and protective covers for the parts. There is one problem, however, Delta’s website states that these kits are not DOT approved, which makes this kit less of a competitor to the law obeying citizens. The reason some HID kits aren’t DOT approved is because they are too bright for street use, so with that in mind, if you live somewhere in the middle of no where or if you have the luxury to use your Wrangler for off-roading more than street use, this kit will light up your path and everybody’s paths around you. Read on your state laws regarding HID kits; if you can legally install this kit, it’s highly recommended. Recommended if you’re looking for a quality HID kit.
