Question: Do LED fog lights need a relay?

A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.

Do fog lights need a relay?

Relays are an important component in wiring fog or driving lights with a 30-60A draw. Basically, the relay protects the switch from getting hot and creating unwanted resistance. The low current through the switch triggers the relay to make a higher current connection to the heavy load of the fog lights.

How many amps before you need a relay?

18 watts, 1.5 amps, definitely no need for a relay. As you get up to 10 and especially 20 amps, youll have more & more need for a relay.

Do you need a relay for LED headlights?

LEDs Need Additional Equipment Unlike standard xenon or halogen bulbs that can be used on a plug-and-play basis (meaning you can unscrew the old bulb and replace it with a new one), LEDs require additional components such as a relay or heat sink under the hood.

Can fog lights be used as daytime running lights?

LED fog lamps can be used as daytime running light on condition that they have an adequate dimming function and are positioned symmetrically on the car front. This is the case for most cars.

How do I choose a relay switch?

An easy way to determine the limit of a relay is to multiply the rated Volts times the rated Amps. This will give you the total watts a relay can switch. Every relay will have two ratings: AC and DC. You should determine the AC watts and the DC watts, and never exceed these ratings.

Why do I need a relay for LED lights?

Which is better LED or HID?

LED headlight bulbs are better and brighter for reflector lenses, while HIDs are better and brighter for vehicles with projector lenses. Although the science behind this is quite complex, the important thing to remember is that you get the appropriate technology for your type of headlight for the best results.

What is the difference between running lights and fog lights?

The short answer is safety. The primary difference between fog lights and running lights is color, with the majority of fog lights being yellow. Yellow lights will shine through fog, dust, snow or rain without reflecting off of the rain or snow and blinding other drivers.

Whats the difference between fog lights and regular lights?

Fog lights are designed to help you drive in poor weather, including thick fog. Drivers typically use their regular headlights in rainy weather. However, main beam or high beam headlights can actually make it harder to see when conditions are foggy. Fog lights, on the other hand, cut through fog without causing glare.
