Default Led turn signal blinks fast

I ordered some white leds turn signals, installed them and now they blink fast as if one is burnt out. But when I turn the hazards on they blink normally. Solutions to this issue? Thanks!

From what I gathered in my own tests, the hazards are not part of the "bulb out" circuitry that results in the hyperblink. The turn signals, on the other hand, will hyperblink if the voltage (or is it resistance?) is outside the range it expects, as would be the case with a blown bulb. LEDs are known to trigger that scenario.

Others will have to chime in on established solutions such as correct LED values or resistors to fake the load.

Amazon.com: 50W 6Ohm LED Load Resistors for LED Turn Signal Lights or LED License Plate Lights (Fix Hyper Flash, Warning Cancellor): Automotive Amazon.com: 50W 6Ohm LED Load Resistors for LED Turn Signal Lights or LED License Plate Lights (Fix Hyper Flash, Warning Cancellor): Automotive

Splice one of these in to the positive and negative wires going to the LED. It'll solve your issue.

You will need a risistor installed in the wire. The led is a lower resistance than stock bulb. So you will need to test resistance on stock bulb then measure on led then get a resistor that is the diffrence between the resistance and install it

It depends what year your SC is, so far I have tried in a 95 and 96 SC swapping the flasher relay to a direct replacement digital flasher relay. The 92-94 SC's have had no luck with it though. If you wanna try it click on my SC400 daily driver build in my sig to see the kind of relay I used. That'll be much cheaper, easier and cleaner mod than splicing a load resistor on each bulb.

If I bought those cables, what is splicing it into the bulb? Sorry I'm not familiar with this stuff

Cut the wire to the bulb and place a resistor in the cut area and tape it up

This is the best way to fix the hyper blink issue: https://www.clublexus.com/forums/sc-...led-tails.html
