    it isolates the strobe heads to minimize the interference that they can put out over the trucks radio
    i would reccomend grounding all of them at the power supply but you dont have to.. even with mine grounded the cb will pick up teh strobes somtimes (counds like the blaster guns in starwars for lack of a better explanation)

    its of no use...unless its real high current going thru the wires which a strobe pack doesnt push u can ground that wire and it reduces rf from the strobe cables as in a shielded wire .... i usually always snip it at the coatin

    Yup, I have never had to use them either. I always snip them to prevent any short circuits.

    They work good to secure the wires to the truck while you are trying to run the wires also. Basically secure the one end with that wire. Then start feeding the wire to where you want it.

    I agree that it should be grounded and only at the controller side. Your controller should also be grounded.

    Yeah, especially since if you don't ground the "controller", your strobes won't work.

    :cool:

    I thought the metal looking wire was for opening the casing further if needed? Learned something new again.

    As mentioned, it's a shielding wire, and is meant to be grounded. The high voltage used can interfere with radios and vehicle electronics. A number of years ago here in Minneapolis, a police van took off unexpectedly and ran over several people. The cause was determined to be ungrounded strobe cables interfering with the drive-by-wire throttle. I don't run any strobes any more (all LED), but ALWAYS grounded them when installing.

    Unless you are referring to an additional incident in Minneapolis, that incident was caused by a tailight flasher. Strobes did not have anything to do with it.

    As everyone else said.

    In the instructions you will see they say to cut the excess off at the strobe head but to gound the wire at the controller side.

    This problem doesn't seem to be a strobe or LED issue either way. It seems like it was a traffic backer, backflasher or other similar device flashing the back up lights and brake lights. Its been recommended not to put these in newer vehicles for quite some time.
    sorry SafetyLighting. didn't see your post uner your quote.

    look at the bottom of the bar near where the cable goes in. there is a screw. that metal wire is bolted on there. its the ground wire for the bar (shield wire) so its not a bad idea to ground it to something but it isnt required.
