wiring connectors

I have a couple dually lights to wire to a switch. Is there some kind of daisy chain connector, or connector to bring all positive to one wire, all ground to one wire? or do I have to just hard wire everything down to one?
If there is a thread on this already (tried searching), point me in the right direction

You can use a standard 2 pin automotive connector (Delphi or similar brand) and jumper the power wire across both contacts. You will have to "double crimp" one contact and use a small jumper wire. Or if you want, you can use a multi splice to hardwire your lights to a single power conductor.
