How-To: Prevent Hyper-Flash for LED Turn Signals

After installing my TSX LED side mirrors, I had noticed that the LEDs were blinking inconsistently (faster) than my incandescent turn signal bulbs. This was driving me nuts!

So, I had recently ordered LED turn signals (front & rear) from V-LEDs and noticed after putting in the rear, that the hazards flashed at a normal speed (60-120x/minute is considered a "normal flash setting") but while using either turn signal, they'd hyper-flash.

A lot of companies like SuperBrightLEDs and V-LEDs sale, what they call, "Flashers" - basically, flasher relays that have been modified to recognize the lower resistance/power consumption of LEDs. These "Flashers" that you can buy are simple PnP applications to replace your OEM Turn Signal / Hazard relay located in your driver-side footwell fuse panel. However, these are only for your common 3-pin and 4-pin relays. Unfortunately for us (7G Accord owners), we have a 6-pin relay in which I have not come across one company that manufactures/sells a "fix" to our hyper-flash problem.

So, with that being said, I set out and did a lot of research and want to thank Roger (from AcuraZine) and Tom (from RidgelineOwnersClub) for their wonderful write-ups on how they accomplished this mod on their cars (Tom's RL and Roger's TL) and to actually FIX the problem at the root, as opposed to just placing a band-aid over it (i.e. load resistors that need to be properly soldered at each and every location a LED is being used)

DISCLAIMER: I am NOT responsible for any damage that may occur or any mistakes that you make. This How-To tutorial is being written based solely as a demonstration document. Proceed at your own risk.

In the end, the Flasher Relay should continue to function properly with any of the following three setups (per side):
(2) Two incandescent bulbs
(1) One incandescent bulb / (1) one LED
(2) Two LED bulbs

Let's begin by gathering the equipment/tools you will need:

Next, you want to open up the relay to expose the motherboard:

(Note: Remember to cut off the excess wire)

Lastly, swap the stock Flasher Relay with your new modified one and enjoy your now normal blinking LED turn signals :up2:

After installing, it worked like a charm! I tested it with two incandescent bulbs; 1 incandescent and 1 LED (rear); and 2 LEDs (front & rear). I no longer have hyper-flash and ALL of the turn signals (front, rear, and mirrors) all blink in sync :D

Sure thing, Matt! Anyone interested in me making them one, send me $40 (the only company I saw that makes one sells it for $80! :eek:) to cover parts, shipping and a little extra for my time and I'll gladly make you one :) I've already sold 2 resistors and used 1 myself, so I can make up to 7 left. First come, first serve. Matt, of course, is first.

LMK in PM. Thanks :up2:

not everyone can solder bro. Even if they can, some people aren't into DIY and would rather just pay someone. They know my price - if they don't like it, they can DIY or go elsewhere. I don't mind either way.

But anyways, BOT:

Ike & Matt, y'all have PMs. 6 remaining.

I really wish more people would take the time to learn how to properly solder. I first learned in H.S. many many years ago in shop class :up2:

But nowadays, it's so easy for people to "wire tap" that they don't care to learn the skill. It truly is a shame, as taps are not reliable at all and 3/4 of the time don't even work. With a good solder joint, you KNOW it's gonna last :)

Jason:

Yours is done, my friend :) Money hasn't even transferred into my bank account yet from PayPal...how was that for speed in getting it done, Sir? Now, I can either ship it out tomorrow and have it to you by Saturday, or wait until Apr 8th to ship it out, as you requested. However, I will be shipping it in an envelope, as I believe it's small enough and the mailman will take it. So even if you're not home, it'll just look like a normal letter. LMK - thanks bud!

Matt: The price has raised up to $40, as the cost of the Duralast switches have raised by $5 + tax. I was shocked. I can start yours whenever you wish so just keep me updated bud. :)

To anyone else interested, I have 6 resistors left. Thanks!

I just placed an order of 4 new switches, one is already paid for by another customer, so I will have 3 left. If another 2 orders are desired, for the remaining resistors, I will place another order. They will be produced the day I receive the switches (they are being shipped 3-5 Day Ground) and will able to ship it out to the customer the very next mailing day :)

LMK if interested. Thanks!

Feedback: Jason (Ikethegreat) has already received one of my switches :up2:

Yes, my switch mod will solve hyper-flash in all of the following with the headlamps ON or OFF:

As per side:
2 incandescent bulbs (stock)
1 incandescent bulb / 1 LED (normal front signal / LED rear or vice versa)
2 LEDs (both front & rear LED turn signals)

Thanks bud - they're modified OEM Acura TSX mirrors

In this thread, I'm referring to the ability of upgrading your turn signals to LEDs though, not the OEM LED tail lamps :)

I received my 4 new switches, this afternoon. I have 5 remaining resistors and 3 new switches + my OEM switch left if anyone else is interested.

@ Clemente: Your switch is done, my friend :) It's already in the mailbox and should reach you in 1-3 days. Enjoy!

I apologize, I just saw this. PM is always the best way to get a hold of me as it sends me an e-mail notification to my phone. Yes, I am selling the modified switches for $40 + s/h + any/all PayPal fees (that you incur). These switches sell online by only 1 business (that I could find, anyhow) and they go for over $80/each!
