Is the bulb for the turn signal and rear light the same?
The topic of today’s installment in the “Car Series” is how to determine whether or not your turn signal bulb has burned out, which is a critical and potentially fatal issue. I am not joking. I’m not trying to kill you.
Let me start with a factual incident. A few months back, Brad and I bumped into our next-door neighbor as we were heading out to take Jack on a stroll. She explained that because her husband was out of town, she was going to a nearby mechanic to get her tail lights checked out. Brad jumped in the car after Brad and I promised to check it out for her, and we ran the standard procedures (which I’ll demonstrate below) to determine what was wrong. It turned out that both of her back turn signals were defective. But things don’t stop there. Her rear lights were also broken because her automobile only had one bulb in it. As a result, she had no back brake lights at all when she braked, which is quite risky. Imagine yourself driving at 70 mph on the freeway when the automobile in front of you suddenly slams on the brakes. The automobile or semi-truck behind you doesn’t see you’re braking until it’s too late because you slam on the brakes, but your brake lights don’t illuminate since your bulbs are burned out. Really, who wants to perish because of a burned-out light bulb? Not I.
However, there is a way to determine whether your turn signal/brake light bulb is about to burn out or has already done so. After we told our neighbor about this, she claimed she had seen the warning and had brought it up with her husband, but he had dismissed her and told her not to worry. Big error.
Here, let’s get back to the fundamentals. There is usually one light bulb per tail light in more recent vehicles. Every light bulb has two filaments. One is for your turn signal, and the other is for your brake light. Therefore, one filament remains on while the other blinks when you’re stopped and your turn signal is on. Get it? Therefore, both your turn signal and brake light are eliminated when this bulb goes out.
How can you determine whether a bulb is burning out or going out in the front or back of the car? The speed of your turn signal in your car is the first clue. You are familiar with the click-click-click sound and the dashboard light that flashes.
Fortunately for me, Brad’s parents’ burnt-out tail light/turn signal bulb when they came to visit this past weekend allowed me to utilize their car as my model. Before they drove the three hours back to their house, we changed the bulb. Security first.)
Here is a video of a turn signal in proper operation. (Watch the video, really. It barely lasts for six seconds.)
This video shows a turn signal that is flashing to indicate a burned-out bulb. (If you skipped the last video, you should view this one immediately.)
When there is a burned-out turn signal/brake light bulb, have you ever noticed how the turn signal accelerates, blinking and clicking faster than usual?
Now, based on the turn signal indicator on the dashboard, we know that at least one of the two right turn signals has burnt out. But which bulbthe front or the backis it? or do both apply? Here’s a method to figure it out: Put your car in a secure spot. Your hazard lights should be on. Look around your automobile to identify any lights that aren’t flashing. Because we knew it was the right rear tail light, I didn’t go around the car for the video, but the hazard lights test in the video below will show you what I’m referring to.
In the following chapter of the car series, I’ll talk about how to change a turn signal/tail light bulb. You can complete this task quickly and easily in your driveway in less than 10 minutes.
I suppose I should wrap up the tale about our neighbor. She purchased two bulbs from a nearby car parts store, went back, and Brad changed the bulbs for her. Here are the neighbors of the year.
Who didn’t realize that a turn signal that was blinking quickly indicated a burned-out bulb?
How can I replace the bulb in my rear turn signals?
Replacing a Tail Light
- Step 1: Open the tailgate or trunk.
- Step 2: Remove the tail lamp assembly (if needed)
- Step 3: Remove the bulb.
- Step 4: Insert a replacement bulb after adding bulb grease.
- Step 5: Reattach the component (if needed)
- Repeat step 6 on the opposite side.
The blinker is blinking quicklywhy?
Ah, that moment when the song filling the cabin and the blinker perfectly time each other. But why, all of a sudden, does my turn signal blink quickly? What are the potential answers, and how large of an issue is this?
Blink on, Blink off
In most cars, the turn signal circuit is rather simple: Battery power is routed through a fuse to a turn signal relay. By activating and transferring electricity through a secondary load circuit, you complete the control circuit when you choose a turn signal direction at the steering wheel. The bulbs designed to turn on when the signal direction is chosen are part of this secondary circuit. The electricity is routed through a flasher since, of course, you don’t want the bulbs to be on all the time.
Different varieties of flashers are typically made with a thin metal strip whose shape is extremely heat-sensitive. The metal strip heats and cools as current passes through it, bending and straightening it to complete or break the circuit. The flasher is therefore temperature-controlled and made to bend precisely at predetermined intervals in response to electrical circumstances.
Why Does My Turn Signal Blink Fast?
The load demand, otherwise known as the lamps, influences the current in part. Despite the circuit’s apparent simplicity, the voltage, current, and resistance were carefully calculated when it was designed. Any of these adjustments may result in a change in blinker speed.
Bad to the Bulb
By far, a broken bulb is to blame when a signal blinks more rapidly. This is so that the blinker receives a varied current when a defective bulb changes the resistance in a circuit.
Test all signal lights to see if any bulbs are obviously out to determine if this is the problem. Otherwise, look for failure indicators like broken filaments or dark, cloudy glass in each turn signal bulb. Check the lights again after replacing any defective bulbs.
Poor Lighting
The blinking speed can also be affected by aftermarket components that don’t fit the intended system, so be sure to swap out any defective components with the proper ones. Avoid upgrading to aftermarket parts that add more lights or don’t take the blinkers into account, and avoid replacing halogen bulbs with LEDs. An erroneous part is unlikely to be the cause of the issue if you haven’t lately worked on the lighting system.
Bad Connection
Resistance and blinking speed are impacted by wiring that is corroded, fried, worn through the insulation, or loose at a connection point. Be wary of poor ground connections. With time, water damage, extreme heat, and other environmental pressures, relays and flashers can become defective. These parts can be easily replaced in order to immediately rule them out as the problem. Just keep in mind to swap like with like.
While a turn signal that blinks quickly shouldn’t cause alarm, it does indicate a circuit issue. Fortunately, the solution is rather simple to find once you know what to look for.

How much does a new turn signal bulb cost?
Your turn signal bulb, which alerts other drivers when you are turning or changing lanes, is one of your car’s most crucial lights. These bulbs are frequently used in cars as hazard lights. To guarantee the safety of both you and other drivers on the road, it is crucial to change your bulb if you notice that it has failed.
In autos, burnt-out turn signal bulbs are frequently encountered. This bulb replacement is a simple do-it-yourself project that typically takes 15-20 minutes and costs under $10.

How can a blinking blinker be fixed?
It may have been easy to swap out a bulb, relay, or fuse in older cars. Modern automobiles have a lot of quirks that might complicate an otherwise straightforward task.
You’ll probably save time and aggravation by taking your automobile to a reputable automotive specialist, particularly if it has an electrical issue underneath.
To fix the fast-blinking turn signal problem on your car:
- Ensure that no wiring is damaged.
- excellent turn signal parts and surroundings
- Replace fuses
- Battery examination or replacement for the car
- change the bulbs
What bulb serves as the turn signal?
The front left, front right, rear left, and rear right turn signals are typically each represented by a different bulb in turn signal lighting systems. They are frequently installed in the headlight and taillight systems. Additionally, many more recent cars have two additional turn signal lights, one on each side rearview mirror. Your rear turn signal lights must be red or amber in hue in North Carolina, while your front turn signal lights must be white or amber.
What is the ideal lifespan of a turn signal bulb?
What precisely is the turn signal bulb, if you’re not familiar with the automotive industry?
The turn signal bulb, commonly referred to as a blinker, is a light that enables you to signal to other drivers the direction you intend to proceed. Because the light turns on and off on the left or right side of your car, in your headlights and taillights, they are often referred to as “blinkers.”
Without the turn signal light, other drivers won’t be aware of your intended turn or lane change, which could cause a crash.
How Long Should My Turn Signal Bulb Last?
Turn signal bulbs should typically last for 4,000 hours. This implies that it will start to fail sooner the more you use it.
Your turn signal bulb will eventually need to be replaced, thus it is crucial to make sure it is operational at all times. Although we know it is unrealistic, we advise you to check your turn signal light each time you get into your car. You should be able to operate your automobile as long as you pay attention to the road and notice when other drivers cease reacting to your turn signal.
Signs That A New Turn Signal Bulb Is Required:
- Other motorists ignore your turn signal When using their turn signal, most drivers’ first observation on the road is that other motorists ignore them. Most drivers will slam on the brakes to make room for a car with its turn signal on to enter their lane. If the automobile in front of you doesn’t try to move over once to permit you into their lane, it could not be anything. However, if a trend emerges, you might want to stop and check your turn signal lights.
- Light Is Not Illuminating Both of your lights ought to be on when you stop to inspect them. When you pull the turn signal lever by your steering wheel, if neither of your turn signal lights turn on, the bulb may have burned out.
- Dim Turn Signal Light You might not immediately notice if your lights are fading. This is frequently one of the first indications that your turn signal bulb is likely to fail but hasn’t yet done so. You have two options if you detect a dim turn signal light: you can be proactive and replace the bulb before it burns out, or you can keep an eye on it and replace the bulb down the road.
- Your warning lights aren’t working. It’s crucial to note that your hazard lights are powered by the turn signal bulb in your car. Hazard lights alert other drivers to an issue with your car. They warn cars to avoid your car if it is stopped on the side of the road.
