Help with basic spotlight wiring

[Jc12]

Hey guys, i have two spotlights (came with bush guard) and two more coming which will be mounted on my roof basket (55watt hellas).. I want to wire them up (NOT to my high beams tho).. just to a switch on its own. I have found lots of helpful info off google but just want to clarify how to wire the lights to the switch properly. Its only going to be a very basic switch mounted somewhere around my dash. I am going to put an inline fuse in (only issue is i dont know the wattage of the lights which came with the bush guard.. they are Hella's i will attach photos incase you guys recognize them). All i know is i wire the lights to the battery (with the in line fuse), the lights are already grounded, then how do i incorporate the switch? Thanks for answering my.. noob question, hopefully i get to make one person feel exceptionally smart today

Anything... Nothing?

Use the switch to activate the coil on the relay. 85 on the relay goes to ground and use terminal 86 as the power feed from the switch. Terminal 87 can go to the lights and terminal 30 can come from a switched source or direct from the battery if you want to have them on when the truck is off. Please fuse terminal 30 to the rating of the lights at the power source. Unfortunately I do not know the rating on the lights you are using. At 55 watts a piece you are looking at very minimal amp draw but the four put together would be a different story. You may want to add a second relay and fuse for the extra set of lights. The fact that they are grounded to the brush guard does not make a difference. Just make sure the chrome is sanded off the mount of the lights and the brush guard so they make a good contact. I have in the past, modified lights like that to have an external ground which makes it less likely to fail over time due to corrosion. Hope this helps.
