What relay is needed to run off vehicle 12volt system?

A relay is not necessary for this light. Relays are generally used for heavy loads (halogen or hid) so you don't get hight current through the switch. With led bulbs the current draw is so low it's not needed.

I didn't run a relay. Just a wire from battery to the hot side of a switch with an inline fuse. Then from the switch to one red wire on a light. Then wired lights together. Then ran another wire for ground and connected it to both black wires. Super easy to install. Great lights.

Its a 12 volt relay. The 14 volts that is in the picture just means that it can handle up to a 14 volt sys. Most automotive vehicles have a 14volt charging sys. But everything works off of 12volts.

Hello, This unit is designed for most passenger vehicles and works off a 12V system. If you have 12V it should work. Good luck.

I built a harness with a relay and hooked it into a remote fuse block I installed, but with the small amount of amps these led's draw, you don't really need the relay, but I would fuse the circuit!Hope this helps you

depends on your car, i bought this kit for my chrysler 300 high beams. because my day driving lights are on the high beams, i needed a relay that would not switch on at 6 volts but would at 12volts. so if this is not a problem for you then you don't need it

No relay needed. 1Positive wire from meter to battery number 1 positive lead. And 1 negative write from meter to last battery negative. Voila!

12v dc with at least a 5 amp fuse or circuit breaker circuit, it is also good to use one with a control relay.

Thank you for your response I ended up ordering a product from AST for $141.00 that will run off my 240VDC low voltage garage opening system no need for a separate 115V outlet as well. Note: If anyone has anything valuable in or garage you need to have an auto-lock system.

The 12VDC is only to drive the relay coils. Use the middle terminal (Common) to complete your circuit. You supply power for each relay. http://electronicsclub.info/relays.htm

none. you have to connect the supplied plug to the 12 volts battery of your car.

No, no need for a relay. There isnt enough amperage. I've had mine for a while with no problem the only thig id do is use different (more durable) wire.

Hi Jake, you will need the wiring kit which contains the relay, the horn voltage is too much for the horn switch and you must use the relay, its not much, about 12 bucks,iirc.

Have a large gauge wire running directly from the battery or alternator to one of the large posts on the relay. Connect the other large post to the radiator fan. Then, run a small gauge wire from your fuse block (usually on a circuit that turns off/on with the ignition switch) to one of the small posts on the relay. Then hook the other small post to ground.

Batteries to keep program when controller is disconnected from 12volt power otherwise you need to program again

First off, you do not need the 12 volt version to control a 12 volt device. You could use the 110VAC version as well since all the device does is open and close relay contacts based on temperature set points. You can route up to 10 amps and 250V through the relay contacts. So, you just run the 12v you wish to switch through the appropriate contact set and then when that temperature is reached the relay contacts close or open. (heating contacts close when a low set point is reached and cooling contacts close when a high set point is reached).

You can hook it directly up to your wiring. No relay necessary. I use these for bow fishing and hook quite a few of them directly to the battery.
