I recently sold my beloved C5 and now I own a C6 Vette. In my C5, I installed a digital flasher relay to combat hyper flashing of my turn signals. I did this because I hated the idea of installing resisters on each signal light on the car. The relay worked perfectly and I never had to deal with those pesky and dangerously hot resisters.

Is hyper flashing an issue with C6 Corvettes?
If so, are there digital relays that will deal with the issue?

FAUEE

Yes. Most of the decent aftermarket taillights have load resistors built in.

In the meantime, before I replace the housings, I want to replace the old-school bulbs with LEDs. Switch-backs for the front turn signals, and LED for the rear turn signals. The interior and side markers should be fine as they do not flash. Are there digital relays for the C6 as there is for the C5?

Dano523

Solid state, in the BCM, and why the flashers when switched out to LEDs need resistors added to them so the BCM sees the correct resistances on the bulb (now being a LED).

When the resistances is out of the correct range, then the flashers will hyper flash to tell you there is a problem (with standard bulbs, and hyper flash means one of them is burnt out).

gpruitt54

So, there is no relay harness (like that available for the C5) which eliminates the hyper flash issues with LED turn signals?

What about non-flashing LED bulb replacements, like back-up, Fog, side markers, interior LED bulb? Will these also cause issues with the lighting system by simply installing them?

Dano523

No on the first question, since if the LED bulbs are built correctly for C6 replacements to start with, they should already have the needed resistors in there assemblies. On some aftermarket builds without resistors in the led plug assembly, you have to cut into the wiring up line to install the needed 12v 50w 6ohm resistors instead.


As for the second question, not on problems since no hyper flasher system to tell you that a bulb is burnt out in those circuits,
other than the LED lightly glowing when the circuit is not fully energized if resistors are not install; but enough LED bulbs/they could be putting out enough RF noise that the RCDLR can not pick up the fob single over the FR noise instead.

DezVette

If you get the switchbacks from JW Motorsports or Vette-Lights, they offer the resistors needed to eliminate hyper flashing.

In re guard to my second question, in order to prevent lightly glowing LEDs, I should put resisters on non-flashing LEDs as well? Am I getting it?

Contact Radio Flyer Innovations. He has the solution for all of your exterior LED's. No splicing into any wiring harness.

gpruitt54

Yeah, I will check out Radio Flyer (One of the most over priced Corvette parts supplier in the country). However, I will keep an open mind and have look see.

Frankly, the idea of resisters dangling off every bulb on the car is a bit ridiculous. But, that's me.

Quality is not cheap !

gpruitt54

Not questioning their quality. I think (rather, I know) you can do the same thing in most cases with a little bran power and effort. For example Flyer sells C5 HID Projector headlights for 500.00, I bought and same thing on another online seller for 120.00. Flyers sells C5 digital relays for 75.00, the same think is available in other online sources for 25.00.

I'll get of my soapbox now.

Seems to me this is posted on the C6 forum. NOT the C5 forum.

gpruitt54

Don't know.

I haven't heard of anyone putting load resistors on the exterior LED's, other than turn signals, obviously.

But the faint glow from the interior LED's has bothered some C6 owners. You can leave one OEM bulb in place, like in the trunk, or use a load resistor to eliminate the glow.

My $.02 on RadioFlyer is that their harness for switchback LED's (front turn signals/DRL's) is innovative and apparently reliable given the lack of posts to the contrary. I'll gladly pay for such a product. YMMV

gpruitt54

Is the LED after glow specific to the C6 Corvette. This was definitely not an issue that I can recall with the C5. I replaced all the bulbs on the car, both inside and out, with no after glow and no resisters.

Knob Jockey

I have no info on the C5.

But in the C6 the glow that comes with replacing all the interior lights with LED's is well documented.

gpruitt54

With my C6, I am only interior lights I am interested in replacing are the map, glove box, and foot well lights. Thanks for the information, I've only owned the C6 for a couple of days, and have much to learn about the car.

VetteLights

The only time you will need load resistors when converting something on the C6 to LED is when dealing with the turn signals and/or tail lights. No other applications require resistors.
The eagle eyes for instance come with a plug & play resistor pack to make for an easy install with no hyper-flashing.
The switchback DRL LED's will require a resistor also (which is included at no additional cost when purchasing from Vette Lights) - Install only requires a pair of pliers for the resistors.
Feel free to reach out if I can answer any questions for you.

I changed to LEDs on the turn signals and yes there is hyperflash but not bad enough for me to install additional resistors hanging in the wiring. It is a faster flash but still very noticeable to other drivers and does not bother me. My big issue is the DRL's which I wanted to be white not amber but this is not the case. The vendor told me it would but that is not correct. Oh well, you cannot have everything.
