Default Slowing sequencial turn signals

Hi,

I installed a sequencial turn signal kit on my 04 and as others have said it is very cool. Very easy to do too.

However, I would like to slow down the sequencing between the flash of each light. The instruction suggested different bulbs like 3357 or 4157 which are higher wattage than the OEM 3057 but I tried that with no improvement.

On a regular car you could install a heavy duty flasher but I know the C5 runs the signals through the hazard flasher module which is not an easy plug and play replacement.

Any other thoughts? As I said, the mod works fine and it does look cool. I just want it to slow down a bit.

Yeah, I know I am a picky pain in the a**. Wife tells me that all the time!

I had the same problem with mine. The sequence was two fast. I checked with the manufacturer and he said the C5 Flasher is in the hazard switch and a PITA to change out. He also mentioned a bypass harness that is available from a forum Vendor (didn't have his name, and suggested doing a search) that allows you to plug in a different flasher without tearing your dash apart.

If you're getting hyperflash, you can either use load resistors or a hyperflash bypass harness. If you're already getting standard flash, the only way to change the flash rate is to add a capacitor to the flasher electronics. This should slow the flash rate by increasing th amount of time needed for the circuit to build up the power to discharge.

Very rapid signal rate caused, most commonly, by the swapping out to LED bulbs from the common OEM incandescent bulbs.

Btw, the subject of the OP is about sequential flashers, which have their own timing circuits, etc and not really a part of the "hyper-flash" problem as far as turn signals generally.

Hyperflash is what happens when the load from the bulb/led is not enough so the car thinks a bulb is out thus doubling the flash rate. This sometimes happens with Halo LED Tail Lights on very rare occasions which can sometimes be reset by doing a certain de-install/re-install procedure. In the event that that does not work, I can supply you with the relay/harness bypass kit for $69 plus about 5-8 for shipping. for those that want to use paypal, you can by sending $74.99 to:

brianrosenberg@gmail.com

You can also get the exact product info here...

or PM me your phone number and I can take credit card over the phone.



You would need this relay if you were to do LED's up front anyway.

Brian

I don't think Florida Mike is talking about hyperflash. What he wants to do is slow down the sequence (a slightly longer delay between each tailight flashing)

I've thought about getting one of those kits but haven't.

I have never heard of sequentials on a vette...that would definatley be a cool feature. I just did a youtube and nothing come up. Anyone have a vid of their C5 with the lights?

Just do a Yahoo or Google search and a few vendors come up. One even just posted last night I believe.

They are pretty cool.

Yes to all who said I just want to slow down the sequence. I don't think a bypass harness would work as I don't have Hyperflash just want to slow the seqence between the two lights flashing down.

I think thats why the manufacturer says use a different bulb. As I said its probably slow for most folks but I want it slower...dammit!

Mike, the harness I was talking about allows you to change out the flasher without ripping the dash apart. There is a vendor on this or possibly another forum, that sells them.

I want to see how to slow down the standard flash rate too! I have the sequencial kit as well.

It can be done. It would require a modification to the existing sequential timing circuit and would thereby increase the cost due to additional components, etc. It wouldn't necessarily dictate a HUGE increase in price, but there would be one just the same.

The circuit would (should) have adjustability for the end-user so that everyone can adjust the rate of sequential flash to suit themselves. What is "fast" to some, is "OK" to others, etc, etc.

The flasher in the dash or the "adapter harness" to use another flasher, is not the answer here.
