Why Flasher Relay For LED Lights Is Necessary
When I first switched to LED lights on my vehicle, I quickly noticed that the turn signals were blinking way too fast or sometimes not blinking at all. That’s when I learned how essential a flasher relay is for LED lights. Unlike traditional bulbs, LEDs draw much less current, and the standard flasher relay is designed to work with higher loads. Without the proper relay, the system thinks a bulb is out or malfunctioning, causing the rapid blinking or no blink at all.
In my experience, installing a dedicated flasher relay for LED lights ensures that the indicators blink at the correct, consistent rate. This not only makes the signals clear and safe for other drivers but also prevents potential electrical issues. It’s a simple upgrade that makes a huge difference in reliability and functionality, which I found crucial after upgrading to LEDs. Without it, the whole lighting system can behave unpredictably, which is definitely not something I wanted on the road.
My Buying Guides on Flasher Relay For Led Lights
When I first started upgrading my vehicle’s lighting to LED, I quickly realized that a standard flasher relay wouldn’t work properly. The LED lights draw much less current than traditional bulbs, causing the turn signals to flash too fast or not at all. That’s when I knew I needed a dedicated flasher relay for LED lights. If you’re in the same boat, here’s what I learned and what you should consider before buying one.
Why Do I Need a Flasher Relay for LED Lights?
LED bulbs consume significantly less power than incandescent bulbs. The stock flasher relay is designed for higher loads and relies on that current to regulate the flash rate. When you replace bulbs with LEDs, the low current can make the relay think a bulb is out, causing hyper-flashing or no flashing at all. The right flasher relay compensates for this and ensures the turn signals blink at a normal rate.
Types of Flasher Relays for LEDs
There are a few types to consider:
- Thermal Flasher Relays: These work similarly to original relays but are rated for lower loads. They’re often plug-and-play replacements.
- Electronic Flasher Relays: These use electronic circuits to control the flash rate, making them more reliable with LED loads. They often come with adjustable flash rates.
- Load Resistor Kits: Not a relay, but sometimes used alongside. They add extra resistance to mimic the load of incandescent bulbs.
From my experience, I prefer electronic flasher relays because they handle different LED loads better without extra resistors.
Key Features to Look For
- Compatibility: Make sure the relay supports your vehicle’s make and model, as well as the voltage (usually 12V for cars and motorcycles).
- Load Capacity: Check the amp rating to ensure it can handle your LED setup without overheating.
- Plug Type: Some relays have standard connectors (like 2-pin, 3-pin, or 4-pin). I found it easiest to get a relay that matches my vehicle’s connector to avoid rewiring.
- Adjustability: Some electronic relays let you adjust the flash rate. This is handy if you change your LED bulbs or add more lights later.
- Durability: Look for waterproof and vibration-resistant models if you’re installing them on motorcycles or vehicles exposed to harsh conditions.
- Brand Reputation: I always check user reviews and prefer brands known for automotive electrical parts.
Installation Tips from My Experience
Installing a flasher relay for LED lights is usually straightforward:
- Locate your original flasher relay (often under the dashboard or near the fuse box).
- Remove the old relay by unplugging it.
- Plug in the new LED-compatible relay. If the connector type is different, you may need an adapter or to do some wiring.
- Test your turn signals to confirm the flash rate is normal.
If you’re adding load resistors, place them near the LED bulbs and be cautious as they can get hot.
Common Mistakes I Avoided
- Buying a relay that isn’t compatible with LED loads — this causes continued hyper-flashing.
- Ignoring the amp rating — a relay with too low a rating can fail quickly.
- Overlooking waterproofing when installing on motorcycles.
- Not verifying the connector type beforehand.
Final Thoughts
Choosing the right flasher relay for LED lights made a huge difference in my vehicle’s signaling reliability. Once I picked an electronic relay rated for LED loads with the correct plug type, my indicators worked perfectly without any annoying fast flashes or errors. Take your time to match the relay specs with your vehicle and LED setup, and you’ll be rewarded with smooth, reliable turn signals every time.
