Okay, this can get confusing, so if it does, I'm sorry.
Is there a relay that has two inputs, the first one being from the main brake light wire, then when power comes from a second source (I.E. the switch for public safety lighting), it switches to a second input and uses that power instead of the main brake light?
The reason being I'm wanting to go LED for my center brake light so I don't get pulled over (Again...) for my light being out, but also make it a part of my lighting for the fire department. I'll be getting a 2-channel LED flasher.
If not, can anyone point me where I can maybe figure out how to make one myself? Thanks.
EDIT: Looks like Sho-Me already had something made up, as far as I know. Anyone else want to help me figure this out and make sure it's what I'm wanting? http://able2products.com/pdfs/11_100...structions.pdf
