How to Replace Under Cabinet Light Bulb

Under-cabinet lights are designed to fit within the confines of your kitchen cabinets. So it would be best if you had a light bulb that would fit into your specific under-cabinet lighting fixtures. You can replace them with various sizes of CFL or LED bulbs, so see which one works in your current fixture and buy accordingly.

Summary: Replacing an under cabinet light bulb is a simple task that can be completed with minimal tools and expertise, restoring the functionality and aesthetics of your kitchen or workspace. Begin by gathering the necessary materials, such as a screwdriver, replacement bulb, and a soft cloth or towel. Ensure that the power to the under cabinet light is turned off, either by unplugging the light or switching off the corresponding circuit breaker, to prevent potential hazards.

First, locate the light bulb within the under cabinet light fixture. Depending on the design of the fixture, you may need to remove a cover or diffuser to access the bulb. This can typically be done by carefully prying the cover off with a screwdriver or unclipping it from the fixture.

Once the bulb is exposed, carefully remove it from the fixture, either by unscrewing it or gently pulling it straight out, depending on the type of bulb (incandescent, halogen, or LED). Be sure to handle the bulb with a soft cloth or towel to avoid damage or fingerprint smudges. Replace the old bulb with a new one, ensuring that it is the correct type and wattage for the fixture. Reinstall the cover or diffuser, if applicable, and restore power to the under cabinet light. Test the new bulb to ensure it is functioning properly, and enjoy the restored lighting in your space.

Tools and Materials

  • Small flat-head screwdriver
  • Replacement light bulb
  • A stool or ladder to climb on to reach the cabinets in your kitchen.

A Step by Step Guide on How to Replace Under Cabinet Light Bulb

Step 1: Determine Whether to Replace or Repair the Light Bulb

Before you go through the trouble of replacing a light bulb, it’s essential that you first determine whether or not your light bulb is broken. If there are no cracks in the glass casing surrounding the filament, then your current issue might be caused by burnt-out filaments. Replacing this light bulb is usually very simple and only takes about 5 minutes. You can tell if your filament is burnt out if one or more sides of the lights inside are blackened when you get close enough to take a look.

This means that heat has been building up inside, causing some parts to get hotter than others until they eventually burned out. To fix it, all you have to do is remove the light bulb’s casing and replace the filament.

Step 2: Turn Off Power

Before you attempt to remove the burned-out bulb, it’s essential that you first turn off the power going to your under cabinet lights. Your circuit breaker might have a switch specifically labeled “cabinet lights” or something like that. Turning this switch off will ensure that there is no current running through the wires of your cabinet lighting system and will prevent any accidents from occurring.

Step 3: Remove Bulb Casing

The casing surrounding most light bulbs made for use over countertops is usually held in place by small screws on either side of the light. The number of screws depends on where you bought them and how old they are. People who purchase recessed lights find loose casings that can be removed entirely without taking anything apart. Other people might need to remove the screws on the back of their light bulbs.

Try to Remove a Single Screw

Simply test it out and see! If you try to remove a single screw and your casing doesn’t budge, then you’ll have to take apart the other side as well.

Step 4: Remove Bulb from Socket

The thing you’ve been trying to get at with a screwdriver is what’s holding the filament in place inside of your lighting fixture. In some cases, this piece is also attached directly to the electrical wires that power your lights, as well as a metal plate that allows electricity from those wires into those very same lights.

In some cases, this piece is also attached directly to the electrical wires that power your lights, as well as a metal plate that allows electricity from those wires into those very same lights.

Step 5: Replace Bulb

If you need to replace a light bulb, first make sure the old one is completely cool before touching it. It’s also a good idea to replace the old bulb with a new one of the same brand and wattage. You can also buy universal light bulbs which fit into most fixtures. Once you have your replacement light bulb, follow these last few steps:

Step 6: Reassemble Your Lights

To fix a broken light bulb, you will need to unscrew the casing around it, replace any metal plates or pieces, and then screw the casing back together. Only do about half as many screws as you took off, so you don’t put them in crooked or tighten them too much. Then, turn your power back on and test your light bulb! If it doesn’t work the first time around, try switching out the new filament with a different one before making any other significant changes.

If neither of those work, then you probably have to take your lights into a repair shop because something more complicated is wrong with them.

Step 7: Reroute Wires

If you are attaching a new lightbulb, be sure to move any wires that could get in the way. Make sure the wires are pushed back as far as possible so you can easily screw or latch on the new light bulb casing. It is recommended that you hold the two metal pieces of the light together with one hand while tightening the casing with the other, just in case the filament breaks again.

Step 8: Clean Up the Area and Power On

If you need to replace a light bulb in your cabinet, first make sure the power is turned off. Then, unscrew the casing around the light bulb and carefully remove it. Put in the new light bulb and screw the casing back on. Finally, turn the power back on and check to see that everything looks good.

Turn the Power to Your Lighting System


  1. Carefully turn off the electricity to the light at the circuit breaker box. If necessary, ask someone to help you, so you don’t get shocked while changing the light. Next, use a small ladder or step stool to climb up and reach the fixture’s cover plate screws. Once these are removed, grasp one edge of the cover plate with both hands and gently pull away from the fixture until it comes free.
  2. Look for an exposed wire connected directly to one of two wires inside the electrical box. The head of each screw also should have wire insulation wrapped around its threaded portion. One or both wires may be white, and the insulation will be white or off-white.
  3. Take this wire in your hand and gently tug it to make sure it’s secure before you unscrew it from the light fixture. The wire should slide right out once you’ve loosened it with a screwdriver. Then wrap the end of a new pigtail wire around it and tighten the screw securely.
Unscrew It From the Light Fixture
  1. Attach the other end of the pigtail to one of two screws on top of the light bulb socket, which should already be visible inside the fixture housing. If there is only one screw on top of the socket, attach the pigtail ends to that single screw. It doesn’t matter which you use as long as both ends are securely attached. Once the pigtail is attached, loosen it to release any slack.
  2. Turn the electricity back on at the circuit breaker to test your changes. If the light isn’t working, check all wire connections to make sure they are secure before calling an electrician for further assistance.

By considering these factors, you can successfully choose the best under-cabinet lighting that will suit your needs and enhance the functionality of your living spaces.

How Can I Tell if My Under Cabinet Light Bulb Needs to Be Replaced

Metal filaments are usually held in place by two metal plates on either side of the flat strip that holds it all together. These strips are generally about an inch long, and can be slid out easily once you’ve taken apart enough parts to get to them. This is a crucial step in how to replace under cabinet light bulbs.

Under-cabinet lights are a great way to add some extra light to your kitchen. They attach to the underside of cabinets above countertops and commonly use halogen bulbs. The lifespan of these bulbs depends on how often they are turned on and their proximity to items that could raise their internal temperatures, such as ovens or dishwashers. The temperature of your under-cabinet lights can also vary depending on what kind of material is used for your cabinets.

Commonly Use Halogen Bulbs

For example, wood cabinets will raise the temperature more than metal ones and may also crack if exposed repeatedly to very high temperatures. How often your cabinet lights are turned on varies among households, with lighting becoming more necessary during meal preparation hours or in homes where children start doing homework after dark.

Frequently Asked Questions

Do You Need to Turn the Power Off to Change a Light Bulb?

There are a few ways that you can do it without even leaving your chair! One of the most common methods is using a ladder or step stool. By standing on the top rung and reaching down toward the lightbulb with an extension cord, you can easily replace it without having to get down on all fours like you would when changing a fuse.

Another easy way is to use a coin-operated flick switch. Just place one end of the wire into either terminal and twist until it clicks into place. Then reach up from below and unscrew the old bulb while holding onto its socket for protection.

Can You Change Light Fixtures Yourself?

Changing light fixtures can be a fairly simple task, depending on the type of fixture you’re working with.

For standard light fixtures that use round bulbs, most people can twist them off and replace them with standard bulbs. For more complex or custom fixtures, such as chandeliers or pendant lights, it may be necessary to hire a professional.

In any case, always consult the manufacturer’s instructions before attempting to replace a light fixture.
