How to replace a Mercury tail light

Cost: $30 to $60, but sometimes as high as $100
Time: 5-10 minutes
Tools needed: Phillips head screwdriver, replacement parts 
Difficulty: Easy
First, you’ll need to figure out what’s causing your Mercury tail light to quit working. Obviously, if your tail light is broken because you backed into something or got rear-ended, figuring out the problem won’t be too difficult. 
However, if you only knew your tail light was out because a law enforcement officer pulled you over, you might have to do some troubleshooting to figure out the issue.
If your brake lights are working fine and only one tail light is out, you probably just have a burnt-out bulb. However, if both tail lights are out or you notice your
brake lights aren't working
either, you might have a fuse or wiring issue.
If you suspect a more complex wiring issue, you can always have a mechanic look your vehicle over and identify the problem for sure.
Once you’ve located the problem, check your owner’s manual to find out the specific parts you need for a replacement. Your manual should list the specific parts and part numbers for your Mercury model and model year.
The process for replacing the tail lights on any Mercury model is pretty standard, with maybe a few differences depending on the model. Here are the steps for a
, but they should work for any model with a little tweaking.  
  • Disconnect the battery. When you’re working with anything that has wires, it’s a good idea to disconnect from the power source to prevent electric shock.
  • Open the trunk. Then locate the mounting screws on the tail light.
  • Unscrew the screws and pull the tail light assembly straight out.
At this point, you can disconnect the whole assembly and replace it if needed. But if you just need to replace a bulb, continue with these steps:
  • Unscrew the bulb socket. Then take out the burnt bulb and replace it with a new one.
  • Reinstall the tail light assembly and secure it with the mounting screws.
  • Test the new lights to make sure they’re functioning properly.
Key Takeaway Replacing Mercury tail lights is easy enough that you can do it yourself with the right tools and replacement parts.

Commons reasons for Mercury tail light malfunctions

In the case of an accident or collision, you’ll know why your tail light isn’t working anymore. But if your lights suddenly go dark, there could be several reasons why. Here are some common causes of malfunctioning tail lights:
  • Burnt-out bulb: If only one tail light is out, it’s most likely a burnt-out bulb.
  • Faulty wiring or fuses: If more than one light is affected, you may have a problem with wiring or a blown fuse. 
  • Corroded socket: If moisture gets into your tail light assembly, it can corrode the sockets where your bulbs are screwed in.
  • Broken control switch: If you replace your tail light assemblies and are still having issues, the problem may be with the control switch. 

Does car insurance cover broken tail lights? 

Depending on your policy, your
car insurance might cover a busted tail light
on your Mercury. However, it’s usually a better idea to skip the insurance claim altogether.
If your tail light was broken in an accident or by backing into a stationary object,
collision insurance
would cover the damages.
Comprehensive coverage
would kick in if your tail light was damaged by a natural disaster or vandalism.
One thing to remember is that before your insurance will pay for the damaged tail light, you’ll have to pay your deductible. 
The most you would pay to replace a tail light on a Mercury is $100. Compare this to the average car insurance deductible of $500, and you can see how you would end up saving money by not making an insurance claim. 
Remember that
filing a car insurance claim
can potentially cause your premiums to go up. So filing a claim for a cheap repair you can do yourself can end up costing you quite a bit of money. 
Key Takeaway It’s more cost-effective to pay for a Mercury tail light replacement out-of-pocket than to file an insurance claim.
