LED Turn Signals - Resistors

bdavis89 · 03-03-2014, 11:06 PM

Has anyone ever figured out an easy (read:non-technical,plug-and-play) way to prevent the hyperflashing when switching to LED turn signals?

I was able to find these "electronic flashers" which supposedly prevent hyperflashing, but I'm not sure which "pin-out" pattern our cars use. Anyone have any input?

could it be as easy as measuring resistance of your factory bulb and your LED, and adding resistors to make up the difference?

You need to place resistors in parallel with the LEDs - LEDs have a relatively high resistance and the BCM thinks the bulb is burnt out. More than one DIY on this site. The resistors can generate a lot of heat so be careful where you mount them.

Edit: Or get "CAN-compatible" LEDs.

Yeah..I don't have any electrical experience. What do you mean "parallel" with the LEDs? That's why I'm looking for a plug-n-play solution. There has been discussion before, but I'm not sure anyone has actually done it.

I'll do some more research on the "CAN-compatible" LEDs.

EDIT: I'm not opposed to learning how to do it via resistors, but its my DD so I don't really can't mess anything up for longer than 2 days (a weekend).

bdavis - the phenomenon is called hyperflashing. search online 'how to fix hyperflashing led.'

GL!

Then I strongly urge you to find someone that knows what they are doing to help you out. The lights on the Z are wired to the BCM, not a relay as in most older cars, and you run the risk of frying something.

The only PnP solution I am aware of is the "CAN-compat" LEDs. But I'm no expert so there may be something else available.

This sounds like your best bet. Or at least the easiest route.

Adding the resistors is not a difficult job just not something I would recommend for someone with zero experience. Shouldn't take someone with some experience more than an hour or so. Unless you burn something up

See my OP? That was the point of this thread and to see if anyone had done it on the 370z specifically.

Thanks! I'll continue to do some research then and see if I can't find a foolproof way of accomplishing this.

in your case, just leave it stock since you need to ask.

Just a quick note. If you are using LEDs for front and rear turn signals you will need 6 ohm load resistors. If fronts only or rears only, then only a 3 ohm load resistor is needed. The resistance value should be imprinted on the resistor itself.
