If you want enhanced visibility for your car while using stylish LEDs, you need to invest in the best turn signal bulbs. Choosing these can significantly improve safety and visibility for vehicle owners, making roads safer. Read our article that covers all you need to know about turn signal lights and their benefits.

Understanding Turn Signals

Have you ever heard of the word blinkers? Well, you can say that is just a casual name for the turn signal lights. Drivers use these turn signal lights to signal the other drivers while turning and changing lanes. Blinkers are now an important part of every modern automotive lighting system.

Just like good quality LED headlights, turn signal lights are turned on by an easily accessible and simple switch. This allows the drivers to quickly indicate their driving intentions to others. The quickness and simple usage of these lights can make driving easier and safer for you and others.

These lights serve as different types of non-verbal communication on the roads. This is why it’s important to regularly check and maintain these lights. You must ensure that these lights are functioning properly and offer proper visibility, especially when you’re driving at night.

Best Turn Signal Bulbs for Different Needs

There are various types of turn signal lights, and you can opt for any that best suits your needs and helps ensure smooth driving habits.

A very common type of signal light can be found in the form of the standard and conventional Halogen Bulbs. If you want something simple, inexpensive, and non-fancy, good-quality Halogen bulbs can work as turn signal lights.

Another common type of these lights is the modern LED lights. If you want enhanced brightness, style, long life, and energy efficiency, upgrading to LED lights is the way to go. These lights come with all the LED benefits while also ensuring you get high ROIs with their quality and durability.

Whether you choose the Halogens or the LED turn signal lights, it is a must to invest in products that are made by top LED manufacturers who offer quality and safety.

How to Change a Turn Signal Bulb: Step-by-Step

Changing or installing a turn signal light is not difficult. All you have to do is follow a few simple steps carefully, and you can easily change turn signal lights in no time.

Firstly, you need to ensure safety by turning off your car’s engine. This allows for easy and safe access to the bulb socket on the front or rear housing where the new light has to be installed.

Then, twist it in the socket in an anti-clockwise direction to remove the already existing bulb. Once you feel like the bulb has been entirely detached from the housing, pull the old bulb out.

Now, install the new and correct turn signal bulb, following the general LED installation tips. This is an important step in the entire installation process and must be done carefully. Make sure you tighten the new bulb and that it sits properly in the housing.

Now, it is time to test the newly installed bulb. If it works, you’re good to go and can reassemble the outer parts of the housing, putting everything back in its place.

If you are using LED turn signal lights, we suggest using a load resistor or a decoder along for better and safer results. It is always advisable to choose a high-quality LED bulb from a renowned bulb manufacturing brand like Philips, OSRAM, or others.

Turn Signal Bulb Not Working? Common Causes

Despite their durability and long-lasting nature, turn signal light bulbs can often face issues and cease to work. It is normal for car owners to panic a bit in such cases. Don’t worry, we’ve got you covered. The following tips are for new drivers who aren’t sure how to fix their vehicle lights.

To tackle the problems with your turn signal lights properly, it is important to know the root causes behind their dysfunction. There are various causes behind your turn signal lights not turning on.

A common cause behind turn signal light issues is damage to the LED chip inside these lights. In case you’re using a halogen light, the burnout of halogen bulbs inside can be the cause of the problem.

Sometimes, blinkers don't work because of the car's internal wiring issues

Sometimes, loosening or corrosion of the bulb sockets can also hinder the smooth flow of electricity to these bulbs, causing them to flicker or turn off. If these lights aren’t working despite a properly secured connection, we suggest checking for any underlying wiring issues or a blown fuse.

It is also possible that you’re using an incorrect or incompatible bulb type, and there’s an LED polarity-related issue with the bulb and the housing. This is common in the case of LED turn signal lights that don’t have any obvious damage but still won’t work.

Lastly, in old vehicle models, there can be a delayed or bad flash relay that slows down or stops these bulbs from working.

Why Is My Turn Signal Blinking Fast?

In some cases, instead of making other drivers aware of your intentions, your turn signal lights can cause disruptions for them. This is true in the case of hyperflashing, where these lights keep on blinking very fast.

This commonly happens when you replace halogens with LEDs like D-series, 360 LEDs, or other plug-and-play LEDs in your turn signal lights. Since LEDs draw less current, your vehicle’s ECU is fooled into thinking that the lights have an issue and hence sends out more than needed current. This causes intense and fast blinking of the lights.

A simple solution to this problem is to add a load resistor in this assembly to manage the current flow. You can also invest in high-quality CANbus LEDs or replace your old relay with an LED-compatible relay system that works well.

Benefits of Upgrading to LED Signal Lights

Like all other LED products, LED signal lights also offer numerous benefits to those who upgrade to them. By installing the high-lumen LEDs, you can experience enhanced visibility and better performance with a hint of style.

The amber colour of these turn signal lights is very attractive and offers great visibility even in low-light conditions. This ensures reduced risk of accidents and improves the overall road safety.

Another benefit of LED signal lights is their energy efficiency. These lights don’t stress the vehicle’s electrical system much to function properly. This minimises the risk of problems for the internal vehicle systems, ultimately benefiting the vehicle owners.

LED Turn Signal Lights: Pros and Cons

The LED turn signal lights offer multiple advantages. The most notable one is the enhanced brightness and visibility offered by them. These lights can turn on and off instantly, saving time and preventing accidents that can happen within microseconds.

Compared to conventional lights used for the same purpose, these lights have a longer lifespan. Ideally, these lights can last up to 50,000 hours.

Another pro point of these lights is their stylish looks, which are enough to add modern aesthetics to any vehicle.

When it comes to their issues, turn signal lights might hyperflash unless managed with load resistors. These lights often show a high sensitivity to polarity and have several compatibility issues.

If you own an older vehicle model, you must expect the least from these lights since most of these only work with modern vehicle lighting systems.

Turn Signal vs Hazard Lights: What’s the Difference?

While both the turn signals and hazard lights serve the same purpose of communicating a driver’s intentions to others, they are used in different ways.

Turn signals or blinkers are used when you want to change lanes or turn. Depending on your needs, you can either activate the blinker on your right side or the left side. These can easily communicate your next move to those walking or driving around you.

Blinkers can indicate the direction one wants to change lanes or turn to

On the other hand, hazard lights are used to indicate an emergency that is causing your vehicle to stop or slow down. In this case, both the right and the left blinkers are used together, alerting the traffic behind you.

It is essential to know when to use hazard lights, fog lights, blinkers, or other types of car lights to abide by traffic laws and ensure safety.

Exploring Turn Signals in Various Contexts

Other than their usage in vehicles to indicate a driver’s intentions to others on the road, turn signal lights can also be used to manage pedestrians and cycling tracks. Here, these signals offer improved safety and minimise the risks of accidents.

Proper usage of turn signals can promote safe driving and responsible behaviours. Those who can use these signal lights properly truly understand their importance in enhancing road safety.

Amber vs White Turn Signals: Which Should You Choose?

Amber signal lights are often mandatory by law in most countries as they are more visible in fog and daylight. These LEDs are legally compliant and offer functionality with safety.

White turn signal lights are stylish and modern, but aren’t legal in most regions. Be sure to check with local authorities if these lights are legal before investing in them.

Yes, compared to the conventional halogen bulbs, LED turn signal lights last longer and offer better performance.

Will LED bulbs make the blinker faster?

Yes, these lights can often cause hyperflashing. It is better to use resistors or CAN bus LEDs.

Can I replace a turn signal bulb myself?

Yes, you can easily do that provided you understand the compatibility basics and legality requirements of your region.

Conclusion

By now, we expect you to understand everything about the turn signal lights and are ready to invest in these for an enhanced driving experience. Make sure to trust and rely on an authentic LED manufacturer and supplier if you want to choose LED bulbs for your vehicle’s upgrade.
