light wiring question

    Working on a 2010 Silverado. I am putting a set of 55 watt lights under the rear bumper for extra vision when backing at night. I know the stock wiring isn't really meant to handle this type of load for any appreciable amount of time. Being as I usually only have it in reverse for a couple minutes at a time, can I just tap into the existing wire for power ?? What says the braintrust ???

    You should use a relay to give power to the lights. Have the reverse wire signal the relay, which you will need to provide with aux power, to turn on the lights you install.

    That's easy enough. Thank you.

    Tapping power from the existing harness for the lights is asking to melt the whole rear harness.
    As Conlan said just use a relay and run a new power wire from the battery.
    Dont forget to put an inline fuse near the battery.

    @ArtO, the safer way is to use the trailer wiring. Use a 7 pin plug, or splice into the lead behind the connector.

    I think it is the middle pin of the connector.

    I know with the Whitenight System it has a relay in the unit and with the new Zxe's I Love it Backing up...:great: After being on the truck for 5 years no problems.. newlights4.jpg newlights1.jpg And it plugs into the factory harness

    I ended up wiring them through the trailer lights. They work great. Thanks to all.
