Even when you encounter a bulb failure in the headlamp then also the turn signals start blinking fast.
Led turn signal bulbs flash fast.
Led bulb load resistors the hyper flash fix.
The reason that the turn signals suddenly stop working after led or smd bulbs are installed has to do with the load put on the signal flasher relay.
1 75 amps of current at 12v.
Hyper flashing also known as rapid flash or hyper flash it s the most common phenomenon that occurs when you change your turn signals to led lights.
Since led turn signal bulbs draw much less power than the original factory būlbs this will cause a sudden drop in the circuit s resistance causing the hyper flash or rapid blinking of the turn.
Read the full guide on how to correct hyperflashing in turn signals.
In this video i take a flasher relay apart and show you how it works and why you need a new one if you change to led flashers.
This mainly happens during the broken or damaged bulbs when the resistance switches start acting abnormally by flashing the light repeatedly at a great speed.
If you don t install load resistors also known as equalizers with led turn signal bulbs you will experience the notorious hyper flash issue.
A flasher unit is incorporated into the turn signal system and is used to momentarily interrupt the circuit to create the blinking action this flasher works on resistance normally present in the lighting system front and rear bulbs.
This causes the bcm to think that a light is out and causes the hyper flashing.
This type of signal flasher relay work by heating up with the current for the bulbs passes through the relay.
A led turn signal will draw a lot less usually less than 5 amps.
Led s draw much less current than filament bulbs.
A standard 21w turn signal bulb will draw approx.
Hyperflashing is when the turn signals blink faster than your stock incandescent bulbs did.
Solving turn signal blinking fast issues 3.
The standard resistor for motorcycle turn signals is a 8 ohm 25 watt resistor which will work on virtually every led turn.
Resistors can go by a few different names some will call it a load relay or load equalizer but what they are going to do is resist the amount of wattage going to the leds.
In many vehicles the signal flasher is a thermal flasher design.
