Very impressive, Would like to know more about the relay? Where did you find the it?

It's a basic 12 volt light relay, you can get it at any auto parts store. They come in Four or Five terminal depending on wiring, four terminal is best or you can not use 87a on a five terminal. You also want to run a fuse between the relay and battery.

OK, this winter installing back up lights is on my list to do..


I am new to the TT world and have a newbie electric question. I have read in many postings about a "relay".
I understand the wiring from the 7 pin and following it back to the junction box to splice into to power the lights.
I understand the idea of putting an inline fuse (what size?) to protect the circuit.


I don't know what kind of relay or why I need the relay. Can you guys help me out?

If you use LED flood lights there's no relay needed.
If you use halogen or a high amperage bulbs a relay is needed. The relay is basically an electric solinoid switch. A small gauge wire is used to trigger the solinoid to pull close contacts. The contacts can handle the high amperage draw from the halogen bulbs.
Typical schematics and explanation here: http://www.r1200gs.info/howto/relay.html

Crew, I've read of folks who are installing LED lights, (the type I am going to install) and included the relay. Is it just an extra then?

I run 2 round LED lights using stock plug wiring and a single14ga wire with no relay to the lights. The current draw isn't enough to warrant using a relay. The wiring can handle atleast 15 amp alone. My two lights are well under 1 amp.
This is the only file pic I have. 1 on each side of the hitch on an angle facing out.
What is the draw of the lights you're using? Check the specs sheet.
