Why LED Turn Signal Flasher Is Necessary
From my experience, using an LED turn signal flasher is essential whenever I upgrade my vehicle’s turn signals to LEDs. The main reason is that LED bulbs draw much less current than traditional incandescent bulbs. Without the proper flasher, the vehicle’s original flasher unit often doesn’t detect the lower current and causes the turn signals to blink too fast or not at all. This can be confusing and even unsafe on the road.
I’ve also found that an LED flasher helps maintain the correct blink rate, keeping my signals consistent and reliable. It prevents the rapid “hyper-flashing” that not only looks odd but can also cause other drivers to misinterpret my intentions. Additionally, using the right flasher ensures that my vehicle’s electrical system isn’t overloaded or damaged by improper current flow, which gives me peace of mind.
In short, an LED turn signal flasher is necessary because it ensures proper functionality, maintains safety, and protects the vehicle’s electrical components when switching to LED signals—something I’ve learned is well worth the small investment.
My Buying Guides on Led Turn Signal Flasher
When I first decided to upgrade my motorcycle’s turn signals to LED, I quickly realized that a standard flasher relay wouldn’t work properly. The LED bulbs draw much less current than traditional incandescent bulbs, which causes the turn signals to flash too quickly or not at all. That’s when I started looking into LED turn signal flashers. Here’s what I learned from my experience and what I think you should consider before making a purchase.
Understanding What an LED Turn Signal Flasher Does
I found that the LED turn signal flasher is a small electronic device that regulates the blinking speed of your turn signals when you switch to LED bulbs. Unlike traditional thermal flashers designed for higher current loads, these flashers work with the low power draw of LEDs to keep the flash rate steady and reliable.
Compatibility with Your Vehicle
My first tip is to check your vehicle’s specifications and the type of turn signals you have. Some LED flashers are universal, but others are made specifically for motorcycles, cars, or trucks. I made sure the flasher I bought matched my bike’s voltage (usually 12V) and connector type so installation was straightforward.
Flashing Speed Options
One feature I appreciated was adjustable flashing speed. Some LED flashers let you set the blink rate to your preference or to comply with local traffic laws. I chose a model with multiple speed settings because I wanted to avoid the overly fast or slow blinking that can confuse other drivers.
Load Resistance and Canbus Compatibility
Since LED bulbs consume less power, my original flasher didn’t work properly without adding load resistors. However, many modern LED flashers come with built-in load resistance or Canbus compatibility to prevent error codes and hyper-flashing on newer vehicles. If your vehicle has a Canbus system, make sure the flasher supports it.
Ease of Installation
I looked for a flasher that was easy to install without needing extensive wiring modifications. Plug-and-play models saved me time and hassle. Also, waterproof or weather-resistant designs are a bonus if you ride in wet conditions.
Durability and Build Quality
Because turn signals are safety features, I wanted a reliable flasher that would last. I checked reviews for products with solid build quality, good heat dissipation, and protective housings that resist corrosion and vibration.
Price vs. Value
LED turn signal flashers come in a range of prices. I found that the cheapest models often lacked durability or didn’t work well with all LEDs. Spending a little more for a trusted brand or a product with good warranty coverage gave me peace of mind.
My Final Recommendations
To sum up, when I bought my LED turn signal flasher, I prioritized compatibility, adjustable flash rates, Canbus support, and ease of installation. Taking these factors into account helped me avoid common problems like hyper-flashing and error warnings, making my LED upgrade smooth and hassle-free. I hope my guide helps you choose the right flasher for your needs!
