does this need a relay ?

Hello, they usually come with the wiring kit, and yes includes relay harness
1001264
NO. this does not draw enough amperage. Hooked mine up with a 20A switch with a 10A fuse. Works great.
1001265
Yes, I put one in. This light only comes with hot and ground wire and mounting bolts.

Hi Jason, You will not need a relay for this and can be hooked up right to your vehicles interior lights.

No. Relays are recommended when device draws considerable amount of amperage. The dome light draws very little amps therefore relay not needed. Installed mine in Polaris Ranger and works great.

Being LED is draws very little amperage. If you are wiring it in by itself, just a fuse will work. I installed it in my wife's 99 jeep on the roll bar and tapped into the existing interior lights.

A relay is included but I didnt need it. Check your furnace set up...chances are you have a 24v HUM hookup on your furnace.

well it depends, i dont think you need the relay, but you may need the harness if your car has never had an alarm before. just to note, this works more like a factory alarm, nothing fancy, its just to open/close doors etc. If the alarm is going off, you would get any indication on the remote

Did for mine. I had originally installed the HID bulbs without relays and found that to be unacceptable. This harness solved my problem but again using HID bulbs which draw less current. 14vdc is optimum; relay will work with less.

They just come with anything but mounting brackets but they only draw about 4 amps so you don,t need a relay just a switch.

i used it to connect an array of solar panels. don't know why you would want a relay, but you could connect a inline fuse if you wanted to.

No, 12vdc is always required on to power the circuit. There are 2 pins that you wire to a simple push button ( must be momentary, not a switch. Like a doorbell button) once you push the button, the time will start. This closes the relay contacts. You use the relay as a switch to control what you like - this can be whatever you like (limited by the relay rating of up to 10 amps 250vac or 10 amps 30vdc You must supply this voltage independently, unless it's 12vdc, then you can use the same supply voltage to the timer. The timer runs its cycle until the next time you press the button

This is not a switch, this is a relay. This in combination with a ball switch or another low voltage switch will work.

You would need what is called a momentary switch. It only closes the circuit while the button is depressed and open when you release the button.Tthen it would have to go to a relay as this switch would not handle the current neeeded for a starter.

I didn't use any relays, since they are LED the current draw is low, If my math is correct, each light draws about 1.5 amps.. I'm using them as back-up lights for my 2003 Ram 2500.

No ...this is just the relay to turn on/off automatic when you start the engine .

No. If I recall, this unit requires at least 8-9V to fire the relay (12vDC).

Yes, if you use two horns you will need a relay. If you use one horn a relay is not necessary. It's a good idea to use an in line fuse if the circuit doesn't already have one.

I didn't but its not a bad idea. how big?no less then 50amps with reset, it depends on how much you draw i don't think you need a relay
2110583
No , if you used existing wire you should already have a relay in line. My horn is not much louter then factory. Not real impressed with this horn.

This is relay could work but it will take other components to do what you described

I installed it on my GMC truck. It works well and has a long range too. It locks the doors, blinks the lights and honks if you push it twice while locking it. I didn't need any additional relays.
