hyperflash problems?
I am thinking about replacing the stock bulbs with leds in my tail, brake, and front directional/parking lamps. Aside from the hyperflash, (I can live with the rapid-fire blinkers as it appears that everything still works) are there any other drawbacks with not installing the resistors to slow things down? Thanks in advance.

I agree a hyperflash harness is cheap, and will fix all your issues. Also without it, there is a chance that your headlights won't always open and close correctly. It's easy and cheap, why not just do it?

Definitely get a Hyper Flash Harness, I have full LED for everything on mine, installed the harness and all works like it should.

Won't have any issues with out it, but another benefit to the hyperflash harness is it will help your hazard switch long term, too. Highly recommended for like $40 and it takes all of 5 or 10 minutes to install.

I agree with all the above - spend the few dollars on the hyper flash harness and have the lights work like they should. Very easy to install - just have to take a few panels loose.

Hyperflash with led lights
I am thinking about replacing the stock bulbs with leds in my tail, brake, and front directional/parking lamps.

Check online for a flasher that is made for led lighting for C5's. They can be hard to find. Check Ecklers Corvette and or West Coast Corvette. They may have them or can tell you where to find them. The down side of using resistors is they will heat up rather quickly and will need precise placement away from anything plastic, other wires, and needs to get good air flow to cool off. I found out the hard way and the wires going to the resistor actually melted wire insulation and shorted out. Someone posted a while back in the forum about a lighting company that makes high quality led lighting with the necessary resistors built in to prevent this problem. They will cost more but for the ease of mind that your beloved C5 wont catch on fire is worth every penny. Ill try to look as well and will post anything of value that I come across. Good luck!

It's basically just a relay with some wire pigtails already put on so you don't have to wire it up. Pretty much any of them worth selling at a price people will pay will make them Chinese.
Those little kids are way better at soldering than I am. It is what it is.

May i ask if you put them in the front headlight harness or rear brake light harness when you have LED taillights and those round projector beam headlights? The headlights are the same stock style bulb but im assuming it goes in the rear brake light harness? I read somewhere it caused the shock sensor out of range code as they run in the same harness or something which since mine has thrown for both front shock sensors.

Nope - the harness goes in the dash under your driver's side knee bolster. Here's a photo of the connector, held in place against the metal of the dash with a push pin:

Here's a short video I sent to my friend to explain it while I was doing mine last week (merged together and uploaded to youtube). Quick, dirty, and to the point. No WHAT'S UP GUYS and 5 minute intro.

Nice to see thats where it goes. May i ask about the resistors they sell in pairs for 13$ and where you install those? That relay is a fix for anyone with front LED sidemarker bulbs as well? The previous owner had installed front LED bulbs on the front corners. Im curious too as mine hyperflash from the rear LED brakelights but wasnt sure if the resistor mod was better seems the relay into the whole circuit is the right idea.

Yep - I still have stock rears and LED fronts only and it fixed it.
The LED corner lights I bought came with resistors, but they weren't good enough. I have a stick (obvious, from video) and if I was on flat ground and not holding the brake, the lights were fine. If I was on an incline and had to hold the brake, the lights would hyperflash with the resistors.
Most of those resistors would need to be tapped in to the wiring at each individual light. So if you did front and rear, you'd need a total of 6. If it's $13 for all, it would be cheaper but this way you aren't cutting any stock wiring. Less potential issues down the road, I say.
