How To Install LED Resistors - Everything You Need To Know | Headlight Revolution

When installing LED bulbs to replace your factory blinker bulbs, you will have a "fast flash" or "hyper flash" problem. This means the vehicle will think you have a light bulb burnt out and, as an indicator to you, will flash quicker than normal. In this video, Chris shows you everything you need to know about installing resistors and shows the best practices and tools to make the job easy.

Installing these resistors will fool your vehicle into thinking it has a light bulb in good condition installed and will blink normally. Simply wire the resistor between the ground wire and the blinking positive wire.

We Do Lighting Better Because We Test!

Best explained/brokedown video on YouTube yet, will be calling for my resistors or bulbs!

[kipdodd]

Dude is better than most I see on tv, easy to follow and speaks well. Keep up the good work Bud!

Thank you for explaining the process of identifying the correct wire. So many other "how to" videos just skip that part by saying they already looked it up before hand and they're just gonna start connecting stuff. There is no assumption in a how to video, other than assuming we're a blank slate and we're watching the video to figure out how to get started.

You are an amazing instructor. Very thorough and can easily understand. I've been a mechanic for years so I understand what's going on but for someone who's just lost on what they are doing you did an awesome video

I have to take time and tell you something
Great job and well done man!
My company policy on this install is very similar to yours.
Your demo is easy to follow and implement to individual situations.
I do question the piercing of all wire jackets…we would actually find the connection before piercing a jacket and possibly allowing a water/fluid/debris contact situation
Please continue making your fun easy to follow and excellent content for all of us!

1996 f350 7.3 auto trans. Swapped my bulbs to LED, put a resistor ground to ground and had Overdrive issues still, this explains better that I need flasher to ground with the resistor. I’ll try that before throwing in the towel going back to factory bulbs.

*Pro Tip* If you wanna avoid ripping part of the sleeve off to test a wire... take a safety pin or a sewing needle, and jam it into the wire you wish to test, then hit the pin/needle with the tester... *Bam!* no broken sleeves!

Holy crap! This is the best tutorial video that answers literally every question I had. The Diode Dynamics video is trash which doesn't have close-ups of where each wire goes into the resistor or the use of either a multimeter or cheapo tester. I think you just got yourself a customer. Thank you!

[adenramirez]

Thank you so much for the step by step instructions. I had replaced my front turn signals with LEDs and it had the hyper flash. I known and heard about this being an issue for others and you helped me figure it out. Stopped by my local autozone and picked up a multimeter and resisters and put em in same day. Thanks man!

[molon]

This video answered virtually every question I had in regards to LED lighting and resistors. Thanks!

I have a 2021 Tundra and both tail lights have (2) wires on the turn signal only. This is great because I didn't need to test which wire was which like you had to in this video (with 3 wires). I appreciate the details in this video including how hot these resistors can get. Because they do. After installing your kit, my blinkers are back to normal pace now. Thank you for this video because it enables dummies like me to do the work ourselves.

[Steve-ohtu]

Resistor goes to ground! Who would of thought. I had all but given up until I watch this video. 20 minutes later the job is done. Thank you.

[PBS-nmuu]

This is one of the best videos you guys have made, you touch on the most important things.

[andreww]

Awesome video. Did the same on my vehicle and never had an issue with my front and rear LED turn signals. Even through intense heat and cold.

[floex]

I was scared to install resistors before this video. So easy with the help of this video, thank you so much!

[daveparrent]

Thank you for this video. After trying several searches and attempting to make sense of some other videos, yours was spot on and answered all my unknowns. I have a 1998 Toyota 4Runner that I had, on the spur of the moment, decided to replace the burnt out conventional bulb with LEDs--I bought Sylvania bulbs. After doing so, I noticed the ABS light on my dash; through a Google search, I quickly discovered I needed a load equalizer, so back to O'Reillys for it. Through other searches, I already knew the wire I needed to tap into with the equalizer was the green one with a white line on it. Instead of attaching the other end of the equalizer to the common wire (white with a black line on it), I crimped a connector on it that had a hole for a bolt, and then I just used the existing grounding point behind the side panel instead. Everything worked--no more ABS light. Thanks again.

NOW THATS A VIDEO ID SAY WAS DONE LIKE A PRO BY A PRO !!!

[mr.boostang]

Never have I done this before and I'm horrible with electrical stuff but your video helped me install some resistors on my 07 Explorer 😁 now my LEDs flash normally 👍

[texaslawdawg]

That’s what I call a professional video. Bravo

[billybrown]

After watching this video I'm confident I can set up my resistors. Thank you.
