Only difference being they don't come on automatically with the backup lights. They come on when you "need" them with a switch. To each his own I guess.wing_zealot wrote:
Why are you using a relay? Just put a switch in the line.
Well because you can only run so much on a circuit before you over load a switch.
Take my Backup lights.
I have halogen backup light on both my TV and 5er! If I tried to run all six of my backup off of the stock backup circuit for power I would be blowing fuses all the time. Instead both sets are on relays, and grab power for a large circuit.
Well the way I wired, both signal and power were very close, so I didn't need to run wires the full length of the TV.
Can't think of a time I don't need backup lights when backing up. :h
Need at night to see, and day time to warn the jerk behind me I am backing up. :B
I don't need a ton of switches, in the cab, and with a switch, might leave on by accident.
