Replacing tail lights on a Jeep Comanche is a practical skill that can save you money and time. Many owners find themselves facing faded, cracked, or non-working tail lights, especially on older trucks. The process is not complicated, but knowing the right steps, tools, and tips makes the job much easier. This guide walks you through everything you need to confidently replace your tail lights, even if you’re not an experienced mechanic.
Why Replace Tail Lights On A Jeep Comanche?
Tail lights are more than just a style feature. They keep you visible at night and signal your actions to other drivers. If your tail lights are not working, you risk fines, reduced safety, and even accidents. Older vehicles like the Comanche often have problems due to age—plastic housings crack, bulbs burn out, and electrical connections corrode.
It’s also worth noting that replacing tail lights can upgrade the look of your truck, making it appear fresher and more well-maintained.
Tools And Parts You’ll Need
Before starting, collect all necessary items. Having everything ready avoids frustration halfway through the job.
Basic tools and parts include:
- Phillips screwdriver
- Flathead screwdriver
- Socket wrench set (usually 8mm or 10mm)
- Replacement tail light assembly or lenses
- New bulbs (if not included with assembly)
- Electrical contact cleaner (optional, but helpful)
- Gloves (to keep bulbs clean and hands safe)
Pro Tip: Buy replacement parts that match your Comanche’s model year. Some models have small differences in the tail light shape or connector type.
Step-by-step: How To Replace Tail Lights
Follow these steps to ensure a smooth replacement process:
- Turn off the ignition and ensure the truck is parked on a level surface. Safety first.
- Open the tailgate for easy access to the tail light screws.
- Locate and remove screws holding the tail light assembly. On most Comanches, you’ll find two or three screws on the side of the lens.
- Gently pull out the tail light housing. Wiggle it slightly if it feels stuck, but don’t force it.
- Disconnect the wiring harness. Press the plastic tab on the connector and pull it out. If the connector is dirty, use electrical cleaner.
- Remove the old bulbs. Turn each bulb counterclockwise to take it out. Inspect for dark or broken filaments.
- Install new bulbs into the replacement tail light assembly if required.
- Reconnect the wiring harness to the new housing. Listen for a click to ensure it’s secure.
- Carefully fit the new assembly into the body, aligning screw holes.
- Tighten the screws without over-tightening. Too much force can crack the new lens.
- Test your new tail lights. Have a helper check that brake, turn, and reverse lights all work.
If any lights do not function, double-check bulb orientation and wiring connections.
Tail Light Assembly Vs. Individual Bulb Replacement
It’s important to know when you need to replace just the bulb or the entire assembly. Here’s a quick comparison:
| Situation | Replace Bulb Only | Replace Assembly |
|---|---|---|
| Burned out bulb | Yes | No |
| Cracked lens | No | Yes |
| Water inside housing | No | Yes |
| Faded or cloudy lens | No | Yes |
| Broken connector | No | Yes |
If you only need to change a bulb, the process is quicker. Replacing the full assembly takes a bit longer but is still very manageable.
Common Mistakes To Avoid
- Mixing up bulb types. Jeep Comanche tail lights can use different bulbs for brake, turn, and reverse functions. Double-check the correct type for each socket.
- Touching bulbs with bare hands. Oil from your skin can shorten the life of new bulbs, especially halogen types. Use gloves or a clean cloth.
- Over-tightening screws. This can crack the plastic, making your new tail light leak water.
- Forgetting to test before finishing. Always check all lights before closing up. Fixing a missed step is easier now than later.
Real-world Example: 1989 Jeep Comanche Tail Light Replacement
Let’s say you own a 1989 Comanche and notice your left tail light is not working. You buy a replacement assembly online, making sure it matches the 1987-1992 Comanche series.
- Remove two screws on the side of the lens using a Phillips screwdriver.
- Pull out the housing and unplug the connector.
- Replace both bulbs even if only one is out. This saves time in the future.
- Plug in the new assembly, align it, and secure it with screws.
- Test all lights with the ignition on and the brake pedal pressed.
Most owners finish this job in under 30 minutes with basic tools.
Choosing The Right Replacement Parts
Buying the correct parts is key. Here are some tips:
| Factor | Why It Matters |
|---|---|
| Model year | Fits properly and works with your wiring |
| OEM vs. aftermarket | OEM matches original look; aftermarket may be cheaper but not always perfect fit |
| Bulb compatibility | Ensures all functions (brake, turn, reverse) work correctly |
| Quality of lens | Thicker plastic lasts longer and resists fading |
It’s smart to read reviews and check return policies before buying. For more part compatibility information, you can check the Jeep Comanche Wikipedia page.
Extra Tips For A Smooth Job
- Keep old screws; some aftermarket kits do not include new ones.
- Clean the connector with electrical cleaner to prevent future problems.
- If your lens is only lightly faded, you can sometimes polish it instead of replacing.
- Store spare bulbs in your glove box for emergencies.
