Will they work well as a back up light when you put truck in reverse or do they need a switch and relay?

They draw about 2 amps each, so if you wire them into your reverse lights, just 2 of them should not draw more than most vehicles are wired for. They'll be more than bright enough.

unless you're going to hardwire them into your existing backup lights you're going to need a separate switch and relay

I don't see why not. I have led lights for back lights, but I found a pair that where flat, rather than square. They tuck in better. I mounted my pair of these square lights on my plow, for added light when plowing at night. My back lights are on a separate switch as I wouldn't want them to come one every time I shift into reverse. So, they will work. If you use a separate switch, go through the ignition switch, otherwise you could run the battery down if you forget to turn them off,

They work very well as backup lights. I wired a 12volt relay and tapped off the positive lead to the reverse lights for power

When you install them just connect to your existing reverse lights by splicing.

I have these lights and they are awesome. I haven't had any issues but I did not use the relay. Power source, switch, lights. It has worked like that all summer and I have two of them hooked up to the same switch. I did use a 30 amp toggle switch.

Wire them directly from the battery with a 2 way switch. They are very low amperage so a relay is not necessary.

I'm not sure I have them as reverse lights and they work great. I couldn't tell you about blinkers.

Not in my opinion. I use mine for my anchor light on my boat and I like that it is very dim when fishing at night. I would not buy them for reverse lights.

I use them for utility lights on the back of my truck. They are not very bright and might not work well for fog lights

I did not use a relay. I used 16g wire. All I did was tap into my reverse light wire from the bundled trailer connections near the hitch. I hope that helps.

I wired mine through my backup lights only comes on when vehicle is in reverse. Originally I had it wired directly was able to turn on and off Whenever I wanted but it would automatically come on every time I started the vehicle got tired of shutting it off so I rewired it to come on only when I put The vehicle in reverse.

I wired mine into the Reverse lightbulb (with an in-line fuse for protection). Red into the hot wire, then ground the black wire to the metal chassis. This way whenever I put my truck in reverse, I get a HUGE light to see when backing up in the dark!

No need for a relay, they don't draw that much power. Do not use them on the road, they are painfully blinding to others, a driver could lose control and hit you.

You could wire it to a switch if you want but the instructions show wiring to the reverse lights. That's what I did. Hey make a huge difference over the stock reverse lights.

As long as you wire the lights to two different wires/reverse lights then the same gauge as your truck is fine. Since they are LED they don't draw too much. I went with 10 gauge so I could add other lights in the future.

They should be powered through a keyed source. If so, when the vehicle is shut off they shut off. If the switch is on when you restart the vehicle they will come back on. I put them in my daughter's truck and, so far, she is very happy with them.

KC makes a set for back up and it comes with the wiring and shielding to run it under the vehicle. They are a defused light that works better for backing up. I have them they're great.

They work as normal. The relay harness just gives you the extra power your HID kit needs to power on correctly. You still can use your light switch to control them, whether to turn your lights off or on.

For reverse bulbs, yes. They are much brighter but in a different way. They have a fish eye lens so they don't really cover within 6' of the rear of the car.

Mount the unit under the rear of the vehicle, making sure that the frame of the unit is electrically connected to the frame of the vehicle. Connect the Main wire to the back-up light wire with a squeeze type T-connector. When you shift to reverse, the unit will operate. You have to connect the unit to the back-up lights and a chassis ground for the unit to know when you are in reverse. The unit is activated by the power fed to the back-up lights.
