Directionals Blinking Fast After Installing LED Bulbs? Diagnose and Quick Fix Hyper Flashing Lights!

Do you have really fast blinking directional lights after installing nice new LED headlight bulbs in your car or truck? In this video, Len shows you an easy fix for the hyper flashing, and explains the problem behind it! The most common cause is the flasher relay, which depends on a specific electrical current from halogen bulbs to function properly. If the current is too low, the relay flashes faster, thinking a headlight bulb is burned out! Because LED lights draw far less electrical energy than halogen bulbs, this may cause the relay to flash quickly!

Check out this playlist for more great tips from Len and the other 1A Auto mechanics!

The relay option is a great idea, but it may only works for older cars. A lot of 2005 and newer vehicles do not seem to have a relay specific to the turn signals, they use control modules instead.

I've went through TONS of led bulbs only to get hyperflash as soon as I install them!
I havent heard anyone up until now talk about replacing the relay!
Thanks for also inspiring me to make my own Ford Ranger videos 👍

Very simple and to the point - thx! I had previously used a resistor for my LED and that was a pain and the wiring looked ugly, glad to know there is a better and simpler option.

THANK YOU! Every video said replace the broken bulb. But you my friend, has the answer!

This guy for sure filmed this at 4:55 on a Friday 😂😂 he went straight to business

Thanks for the help! I love the light setup and I’m planning on doing the same to my K1500. I was hoping you could leave part numbers for all the bulbs you used as well as the relay.

Good stuff Len!!! Good look on the truck.

P.S. Hey Sue….maybe back Len away from the caffeine before vlogs!! WOW!!!

Thanks for posting this video. It drives me crazy when I see vehicles with fast flashing LED lights.

What if you only replace one set of bulbs? Will the new relay work with leds in front and incandescent in rear? Or do I have to replace all of them?

[Blexyyyy]

Was putting in led turn signals and got hyper flash even after double checking them multiple times, this video helped and also your truck may have a bigger relay box than the one in the video like mine, double check by looking at yours before you buy one

Another good way to fix hyper flashing lights is to remove some blinker fluid from the bulb.

I like the variable timing feature on the new flasher relay.

[waynehutchinson]

As always, you are my go to guy for troubleshooting, thanks for the video

[bootyaa]

Hyper flashing wouldn't be so bad if it wasnt for the noise it makes lol

[dieglhix]

Just upgraded to Led and having this funny situation, thanks for the video!

[JamarD]

So get a relay? Got it. Thank you! I want to install switch-back led turn signals. Hopefully, this will work as you've shown.

[jamesvertrees]

Thank you! You are the go to guys for straight forward info.

Thank goodness for A1 auto you gave my subscribe

Have to say cutting the wires is a very bad idea you are absolutely correct replace the relay
