back up alarm

so i bought a back up alarm just thought it would be neat. so i bought one, i have fog lights on my bumper wired in to the reverse lights, when i hookup the back up alarm it does nothing, when i unhook one of my lights and hook up my back up alarm it works fine, any solutions?

 

nothing guys?

 

Still nothing

 

Why are you using your fogs? Use power from just your reverse lights.

 

I tried that too it just makes a click noise until I unhook the fog reverse lights. Then it works fine

 

The back up beeper on my old welding rig was hooked up to my reverse lights. I also had spotlights connected and never had any problems. Don't know what to tell you

 

Well thanks anyways guys
