Title: How-To: Prevent Hyper-Flash for LED Turn Signals Post by: DreaminAccord on February 24, 2013, 08:41:07 PM 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: (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayEquipment_zpsaf1d5aac.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModResistors_zps8fcb39d8.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModFlasherPN20314_zps3a591b52.jpg) Next, you want to open up the relay to expose the motherboard: (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalFlasherRelay_zps7b56236d.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModBackSolderPoints_zps78c32ad7.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModOldVSNew_zps9cb6fae4.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModOldRemoved_zps7a62868b.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModNewInPlace_zps1f34e292.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModNewSolderedRear_zps24ecd497.jpg) (Note: Remember to cut off the excess wire) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModNewSolderedFront_zpsba3b0d8e.jpg) (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/TurnSignalRelayModReassembled_zps9f61091d.jpg) Lastly, swap the stock Flasher Relay with your new modified one and enjoy your now normal blinking LED turn signals :thumbsup: Relay location: (http://i1056.photobucket.com/albums/t377/DreaminAccord/Turn%20Signal%20Flasher%20Relay%20LED%20Mod/07486E8D-7A32-4F1D-87BE-5FD9261D6DE0-12843-0000024C98222841_zpscba2f8e6.jpg) 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 :thumbsup: (http://i1056.photobucket.com/albums/t377/DreaminAccord/AE7301C6-9F55-4A8E-8714-B96CC195E7F7-12843-0000024C9E41CB93_zps4971052c.jpg) Title: Re: How-To: Prevent Hyper-Flash for LED Turn Signals Post by: HEcreated487 on February 25, 2013, 12:11:58 PM :thumbsup:
