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.
Do I need a relay for LED lights?
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.
Can you wire LED light bar without Relay?
A relay is an electrical switch. It allows a low current “switch” circuit to control the electricity flow of a high-current circuit load, like your LED Light bar for example. … You don’t need a relay for LED’s. You’ll have three wires going to the switch if you’re going to use a lighted switch.
Do I need a relay for headlights?
Every so often, the question arises – should I add relays to my headlight wiring. The answer is yes! … Power is conveyed from the power source (battery/alternator) to the lamps via the wires, connectors and switches. To ensure maximum power delivery, there should not be any power loss in the circuit.
Can you put LED bulbs in stock headlights?
Can I put LED bulbs in my stock HID headlights? No. LED headlight conversion kits are only designed to work with stock halogen bulbs and assemblies.
What amp fuse do I need for LED lights?
75mm is good for about 7.5 amps max. I generally like to have at least 100% extra rating so a 3 amp fuse max is what i would use. This should be plenty for 4 leds. If you have working leds but blow a 10A fuse i think your wiring needs checking and you will probably find your fuse is directly across the battery.
Why do LED lights have 3 wires?
LED Lights with 3 wires will be a multi-function light. They can (most times) be used in whatever configuration is right for your application. For example, running and brake, running and blinker or brake and blinker. These LED’s will usually have a black, red and white wire.
Can I use 18 gauge wire for LED lights?
Most people would likely recommend using a solid core 18-gauge wire for your LED lights. The cost difference between this wire size and a much smaller cable is negligible, and 18-gauge is about as big as you can go if you would like your wires to fit into most holders or terminals.
Why use a relay instead of a switch?
One of the most common situations that require the use of a relay occurs when an application needs to switch from high to low current (or vice versa) within the same circuit. For example, the temperature sensors that power HVAC units require levels of amperage that vastly exceed the capacity of their wiring.
Does a relay need to be grounded?
When hot switching voltages above the coil to case dielectric voltage rating, the relay MUST be on the ground side of the load (see Fig. 2) and the case MUST be grounded. For hot switching voltages lower than the coil to case dielectric voltage rating, the relay can be on either side of the load (see Fig.
What are the symptoms of a bad headlight relay?
Symptoms of a Bad or Failing Headlight Closure Relay
- Headlight doors don’t open. One of the first symptoms of a failed headlight closure relay is headlight doors that don’t open. …
- Headlight doors stuck open. …
- Headlight doors operate erratically and open or close on their own.

How can I increase the power of my headlights?
The most important thing to remember is that if your car came with halogen headlight capsules in reflector headlight assemblies, you should look for brighter halogen capsules. Installing HID capsules in a reflector headlight assembly will result in brighter headlights, but the beam pattern is typically awful.
What is the purpose of a relay on lights?
Using a relay keeps the high current portion of the circuit away from the switch and pulls the current directly from the battery to your KC’s. The relay also allows you to tie your lights into a secondary 12-volt circuit such as your high/low beams or ignition.
Should I upgrade to LED headlights?
LED headlights are much brighter, revealing more of the road and your surroundings. This benefit also goes two ways, as oncoming traffic will have an easier time seeing your vehicle. … However, you should come out ahead in the long term as LEDs are more energy efficient and may last longer than halogens.
