If you want to build the relay setup yourself instead of using a commercially produced motorcycle headlight relay kit, you'll need two automotive relays, commonly called "Bosch relays". They should have a rating of at least 10A, which they nearly all do (generally you find them at least 20A).

Is there a relay for headlights?

Used in “flip-up” lights, which fold out of the body of the vehicle, headlight closure relays are essential for headlight operation. This relay is located in your main fuse box or panel.

How many headlight relays do I need?

You will need two relays – one for low beam and one for high beam. The relays are hermetically sealed and are available for a few dollars from any auto store.

Do I need a relay for LED lights motorcycle?

You shouldn't need to use a relay for LED conversion. They do not pull any more juice than the standard bulbs. It's recommended for HID conversions since they pull a lot of current when they ignite, and they often cause voltage spikes/fluctuations.

Why do my headlights not work but my brights do?

Like all electrical systems, the headlights in your vehicle have a fuse in the circuit to prevent too much electricity from reaching the bulb. There will also be a headlight relay that switches power from the low beams to the high beams. If the fuse goes bad, you likely won't have any headlights at all.

What are the symptoms of a bad headlight relay?

Symptoms of a Bad or Failing Headlight Closure Relay

How much does it cost to replace a headlight relay?

$79.99 - $99.99. All relays, including your headlight closure relay, are used to keep high amperage and voltage systems away from the driver as a safety measure. Used in “flip-up” lights, which fold out of the body of the vehicle, headlight closure relays are essential for headlight operation.

Are high beams and low beams on the same circuit?

Most modern vehicles have a single bulb with two filaments. ... Some cars (mostly higher-end vehicles or performance vehicles) do have separate bulbs for their high and low beams. Generally, you'll have a standard halogen bulb for low beams, and then an HID bulb for your high beams. These are not interchangeable.

Where is the headlight relay?

Find the headlight relay closure:

Usually, it is under the hood of the car. The point where your fuse panel is most likely located. On the other hand, it may also be located inside the cab of the car, this would be the case if your car comes with an interior fuse box.

Can you straight wire headlights?

And you can happily run 110W bulbs all day long and not fry wires. In short - you wire your headlights directly to your battery. But to make sure that you can still turn them on and off, you put a switch in the line.

What is the purpose of a headlight relay?

Headlight Fuse or Relay

This protects all the components on the circuit. If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights.
