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.
Led turn signal bulbs flash fast.
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.
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.
Even when you encounter a bulb failure in the headlamp then also the turn signals start blinking fast.
Hyperflashing is when the turn signals blink faster than your stock incandescent bulbs did.
A standard 21w turn signal bulb will draw approx.
Hyper flash is exactly what it sounds like where the turn signal light flashes rapidly and is almost headache inducing.
Led bulb load resistors the hyper flash fix.
The standard resistor for motorcycle turn signals is a 8 ohm 25 watt resistor which will work on virtually every led turn.
This type of signal flasher relay work by heating up with the current for the bulbs passes through the relay.
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.
A led turn signal will draw a lot less usually less than 5 amps.
No worries it s an easy fix.
Led s draw much less current than filament bulbs.
This causes the bcm to think that a light is out and causes the hyper flashing.
This happens because your new led bulbs draw such little power that your turn signal relay sees the bulbs as being out.
Read the full guide on how to correct hyperflashing in turn signals.
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.
In many vehicles the signal flasher is a thermal flasher design.
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.
