Nice!! Great job and picture

 

Only assumptions here on the wire colors, since the aftermarket harness for the Euro taillights might use different colors, and my Vette is not here today.
The harness for each side of the vehicle has four connectors; two go to the taillights, two go to the turn signals. The two that go to the turn signals should have two wires going to each light socket. On the GM wiring schematics for Euro lights, the left side would be yellow and black, the right side would be green and black.
Black denotes ground on both sides. Therefore, you would want to install the resistor between the yellow and black wires on the left side, and another resistor between the green and black wires on the right side. Make sure to install after the two wires go from the socket to the splice in the harness.
Hope I explained that ok.

To prevent having to do this splicing of resistors, you can do a search for electronic turn signal flasher modules. They make turn signal flasher relays that replace your existing flasher relay, for applications that are using standard and LED bulbs. These electronic relays (modules) do not require heat to make them work.

Another old trick is to take apart the existing turn signals flasher relay, and adjust the spring tensions of the contacts. Heat makes the contact expand and pull away from another contact, when the heat is reduced due to installation of LEDs, the contact can't expand due to heat and therefore, no blinking. Bending or adjusting the spring tension to blink due to the heat created in the circuit from the front bulbs can also work.

 

Somebody out there must have already figured out an easy way to modify the switch in the dashboard so that LEDs don't flash crazy fast. I mean, the integrated blinker switch in the dashboard doesn't blink crazy fast when the hazards are turned on, just when the signals are used. So, has anyone modified one to always blink at the hazard rate when the signals are used?

 

Older cars had two different flasher relays to solve this problem. However, turn signals and hazard flashers go through the same "electronic" flasher relay as indicated on the GM wiring diagrams. I'm wondering how much of a drop in resistance in the circuit will the "electronic flasher relay" handle.

 

i received this reply about the bulbs working with my sequentials. if anyone wants to give it a shot, it may work.

HI-

I have another customer with the same set-up.

I am not certain exactly how this will all work together.

You need 4x 3157 bulbs for the rear of the Vette.

The other customer purchased 4 6 ohm equalizers. I am pretty certain it will
all work, but it may require some trial and error to fins out the correct
combination.

It is also possible that you will only need 2x 6 ohm equalizers, but I am not
certain.

I can help you work this out as you try it. I am anxious to understand the
details of the Corvette wiring better. The Corvette is somewhat unique from
other vehicles in the way the rear lights operate.
________________________________________ ________________

Here are the basic instructions:

If using leds for turn signal applications, or in vehicles that have built
in dashboard bulb-out warning systems (such as BMW Mercedes and others) ,
load equalizers may be required.

Use two 3 ohm equalizers if you have led turn signals in both the front and
rear (2 bulbs per circuit). Use two 6 ohm equalizers if you have led turn
signals in the rear only , or front only (1 bulb per equalizer).

I have Clear/Red Euros, so this seems to be easy. The clear part of my light I use Titanium Bulbs so they don't look like Egg Yolks, but when you step on it, it is amber.

I guess I just replace the 4 red lights, or top Bulbs witht the red light he got.

Cool Thanks LED's are getting big. Any of you see SpdKills website and post on here, he did led's on the inside for all his lights, in blue, looked cool.


Thanks

 

Dave it looks great. Very nice job. You the man.

 

OK this was me! I told Chris I would give it a go.

I just got done figuring it all out, 4 LED tower bulbs and 4 - 6ohm load equilizers.

I did each one, one at a time so that they worked. The load equalizer on the drivres side went ground to outer lead. I then made sure the tail lights worked then the turn signals. Man, the LED's make the sequencials work like they are suppose to!

I did the passengers side next. Here the equalizers had to go ground to center lead. Again made sure the tail lights worked, then the turn signals. I am thinking, this is cool!

Then I figured, lets try the emergency flashers. Push the button....man they look cool....chime, chime, chime...What the heck..look and the DIC is flashing "Service Traction Control" "Service Active Handling". I clear the code and try it again..same thing!

So needless to say, I took it all out and put the bulbs back in, clear the codes and now after everything is returned to normal, I turn on the flashers and it is still throwing code C 1295H.

 

pretty lookin'

 

Hi....

Ok I'll try to keep this short. About 2 yrs ago I installed the turn signal sequencers and for about the first 4 weeks all was fine. Then out of nowhere one night (at 2AM) I started throwing all those same codes:

Service Traction Control
Service Active Handling

and then it went into reduced power mode and couldn't go over 25 MPH. Had to have it towed in. Did they fix it? They thought so. Each time. After about 5 trips to the dealer over the next 3 weeks, (didn't go into reduced Power mode ever again) with them replacing modules/parts of all different types, it just wouldn't go away for long.
The last time it was there, they had it for over a week trying to figure out what was causing it. It was getting rediculous! Finally, they did metioned something about the computer being very fussy to voltage fluctuations and that seems to be what's causing the problem but they couldn't figure out from where. So I mentioned the "blink-blink" mod on the tailights that had been made 4 weeks prior to all this and the mech. right away said "that's gotta be it".
Bottom line, they removed them and it's never happened again.
I'm afraid it may not be the LEDs at all, or it's a combo of the two. Why it seems to work on some cars and not others, or why it works for a while and then bang....who knows? You might want to try losing the "blink-blink" and see.
Anyway, just wanted to share my experience. Good luck.

Man, those look great!

 

When I set the hazards I get the same message to service traction control. I have stock bulbs and flashers, how often did you use your hazards before? Maybe the problem was there already? I have had my car for almost a year now and wouldn't have known except I was doing some tweaking of my stereo on the side of the road and though I should put the hazards on just in case, and that's when i noticed the message.

 

Thanks for the great info cselz! I (I'm sure with others) really appreciate the effort you guys make to help out each other I might be getting the amber LED's for my signals next month, so I'm curious what's gonna happen (I have the euro lenses)

 

Awesome!

 

I just received a set for my Euro lamps and man, what a difference!

 

Hello,

Has anyone gotten this to work with their C5 that's equipped with sequential turn signals? I followed the instructions that 14U2ENV provided above and installed both driver side lights.

On both lights I used a 6ohm load equalizer and I can't quite get them to work properly. If I turn on the lights, both lights light up, but they are as bright as they can be. (Like the brake is applied.) If I step on the brake, both lights dim slightly. (The opposite of what needs to happen.) The turn signals worked once and now won't come on at all. (The sequential turn signal mod did not work the one time I did get them to work, both bulbs flash at the same time.)

I tried removing a load equalizer from the drivers side innermost light and that did not work, the turn signal flashed super fast. I reinstalled that one and removed the outermost load equalizer and got the same result.
Not a big disaster, if I remove the load equalizers and put the stock bulbs back in, everything returns to normal. Just curious as I really like the LED look, but not sure I have the skill to figure the electrical thing out.

Thanks !!!
Gene

 

Hi Gene-

First off, thanks for sharing the details.

You know what? I tried using the fast blink (holding the signal wand half way) on someone's car that had the sequ. light mod done. Seems like, the outter light does not get enough juice if the power doesn't stay on long enough.
In your case, I think the resistence is too low with the LED's installed, in combination with the sequ. mod? Seems like it's cutting the power to the bulbs too fast? Maybe the load equalizer is resisting enough. I have to see the wiring to really try and sort this out.

FWIW, I really appreciate you trying to get this to work. I'll be at it myself soon. I'd like to find a resolution for everyone's sake.

Its mod time again.
