Why Are My Led Lights Not Bright? – 5 Reasons You Need to Know!

Yes, car owners switch to LED lights from halogen headlights for better and brighter light. But, as you know, electronics are pretty unpredictable, so do LED lights. Often riders complain that the LED lights on the headlight don’t emit proper lighting; to be specific, the lights are not bright enough.

The reason why LED lights are not bright can vary from a faulty wiring system or a poor power supply to burning out. What caused your car’s LED light to dim down is something that you need to audit and look through.

In this piece, we are going to look at some of the most common reasons for dimming LED lights that you need to be aware of.

Performance of LED Lights

Generally, LED lights are quite satisfying to use. These lights are brighter, affordable, and last for a decent time. However, there are occasions when LED lights can get dimmed and offer poor lighting.

So, what goes wrong? What exactly are the reasons for LED lights getting dimmer? Let’s find out!

Reasons Why LED Lights Are Not Bright

So, here are some technical issues that may cause the LED light on your car headlight to dim, even if you’ve spent on the best-branded ones.

1. Poor Power Supply

Lack of proper voltage or current can definitely affect the brightness of the LED lights. While you are connecting the LED lights to your car’s headlights, you must make sure that the power supply is accurate and suits the requirement of the diodes. If the power supply is improper or not quite up to the mark, the light won’t be shining as it’s supposed to.

What you can do in this case is contact an expert technician, assess the power supply that the LED lights are receiving from the batteries, and repair it or retune it. In extreme cases, an oversupply of current can burn the lights out, too. So, a proper connection is necessary.

2. Loose and Faulty Wiringsloose and faulty wirings of car headlights

Another reason for dimming LED lights is faulty and loose wiring. It’s not that the connection has been loose since day one, but this can happen over time.

If you are riding on rough roads quite often, the internals of your vehicle is sure to shake up. However, while this is not something to be worried about, certain wirings inside the mechanism can get loosened or faulty.

If the wiring happens to be linked to the LED light on your front, it will definitely cause the light to dim down. Plus, occasional flickering will be an added hassle to deal with.

3. LED Light’s Age

How long you are using the LED lights has a lot to do with its performance. In our LED vs. Halogen light article, we have discussed this as a key difference between LED light and halogen. Although LED lights come with brighter light, it tends to dim down over time, unlike halogen lights.

So, if you have been using the lights for a long time now, it’s probably because of the age of the diodes that are causing the reduction in brightness. It’s better to replace the lights if you’ve been using those for around three years.

4. High Ambient Temperature

If the surrounding ambient temperature is very high, the brightness of the LED lights should drop. Generally, LED lights emit the highest brightness at around 25-degree celsius temperature.

However, if the environment temperature is around 40 to 50-degree Celsius, the brightness will surely drop to 70 to 80 percent. That’s why LED lights shine the brightest during winter and cold days. 

5. Not Enough Lumen Output

Before buying an LED light, you need to understand the lumen output of the light. Lumen output generally refers to the brightness of the LED light.

The more lumen output rating the light has, the brighter it is going to shine. So, if you have bought a set of LED lights with a lower lumen rating, it’s not going to shine like the ones with higher lumen ratings.

Final Words

So, that answers the question – why are my LED lights not bright! There are plenty of reasons behind the LED light of your car headlight getting dimmer. The good news is, you can solve every one of them on your own! So, make sure you identify the problem pretty clearly and take action accordingly.
