Why are my LED blinkers not working?

Why are my LED blinkers not working?

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 many vehicles, the signal flasher is a thermal flasher design. The amount of current drawn by the bulbs is required to properly activate the thermal flasher.

Does a flasher relay need a ground?

So with a 1157 circuit you must locate the blinker input and connect to that from the flasher relay. Ground must be connected to ground.

How does a LED flasher relay work?

It’s that current flowing through a bimetal that completes the circuit and turns on the front and rear turn signals—that current also heats the bimetal strip, causing it to bend and open the circuit, which shuts off the lights. The strip cools rapidly and the cycle repeats, making the lights flash.

Do you need a flasher for an LED turn signal?

Yes, even if you go with LED bulbs in your turn signals you will still either need a replacement flasher relay or load resistors across each LED turn signal bulb.

Why does my LED flasher Blink so fast?

Hyperflashing is when the turn signals blink faster than your stock incandescent bulbs did. This happens because your new LED bulbs draw such little power that your turn signal relay sees the bulbs as being out. Installing an LED flasher module specifically designed for LED bulbs.

What should I do if my LED light is not flashing?

Electronic Signal Flasher Relays are a simple and effective upgrade because they are a plug in replacement for the factory flasher. Upgrading the signal flasher resolves the problems associated with LED conversion about 95% of the time. They are the recommended solution to the problem, but they are not the only solution.

Can a car Flasher be replaced with LED light?

These bulbs can easily be replaced by LED units, but there is one important thing that you need to bear in mind. The old type of flasher relay units need a certain amount of current in order to work; that’s why on some cars the indicators won’t flash if one of the bulbs has blown.

What do you need to know about LED flashers?

What is an LED Flasher? An LED (-compatible) Flasher is a turn-signal or hazard flasher relay that works properly with LED turn-signal bulbs. Generally, a stock automotive Turn Signal (or Hazard) Flasher Relay does not work with LED Bulbs unless it was designed for that.

Can a car Flasher relay work with LED bulbs?

Generally, a stock automotive Turn Signal (or Hazard) Flasher Relay does not work with LED Bulbs unless it was designed for that. If you replace incandescent (regular) bulbs with LED Bulbs, you may notice one of two malfunctions: Either the lights will not flash at all, or they will flash fast/eratically, the latter is known as Hyperflashing.

Do you have to ground a thermal Flasher?

This wire needs to be connected directly to ground. In the simplest case, that would be a piece of sheet-metal of the vehicle. The reason your flasher may have this is because none of the terminals of the flasher socket in the original vehicle design was grounded. Old style thermal flashers don’t need a ground, but LED compatible ones generally do.

Can a solid state Flasher be used with regular light bulbs?

Compatibility: All LED flashers from CEC, including the Solid State flashers, are compatible for use with regular bulbs as well as LED bulbs or a mix of LED / regular bulbs. There are many cheap LED flashers on the market that will simply go up in smoke when you put regular bulbs in.
