Do you need a special flasher for LED turn signals?
The reason most mechanical flashers won’t work with LEDs is that they require very little current flow, which is not enough to heat the internal strip and open the circuit. There are several types of electronic flashers available, however, not all of them are for LED applications.
What is the difference between a flasher and a relay?
The hazard and turn signal lights found on the vast majority of road going vehicles are controlled by a flasher, which is commonly referred to as a relay. The flasher is an electrical component that serves as the switch that allows the lights to flash on and off.
Why do my LED turn signals not flash?
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. In some vehicles, when the load drops below the amount required by the flasher relay, the relay will not reach temp and the bulbs will not flash.
Why is my blinker so fast?
A bad bulb is by far the most common reason that a signal blinks faster. This is because a bad bulb alters the resistance in a circuit, sending a different current through the blinker. Otherwise, inspect each turn signal bulb for signs of failure such as broken filament or dark, clouded glass.
Can you use LED lights on turn signals?
Yes, LED bulbs will work on a vehicle even that old. A replacement flasher relay will be required for the turn signals. Unfortunately, we do not have any full vehicle kits. You would have to remove your original bulbs to see what is there and how many you will need to replace with LED bulbs.
How to change your turn signal bulbs and upgrade?
What you need to do then is to trick your vehicle’s ECU into thinking that your newer LED bulb has the same resistance and power consumption as the bulb you are replacing. When you upgrade to the LED bulbs, you just need to make sure you connect a load resistor across the wires feeding the turn signal light bulb.
What happens when you change your turn signal?
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.
Can a turn signal bulb be used without a resistor?
Some people get lucky and the LED bulbs work without a load resistor, mostly because their later model vehicle turn signal ECU is already LED compatible. In those cases, it’s not because of any resistor built into the LED, it’s just the LED compatible flasher unit.
