Stupid newbie light question

So, I want to mount 4 or 5 LED lights to the top of my Prinsu rack, instead of a light bar. Most likely the Baja Designs LP9's. Is it possible to use only one hot wire positive + wire for each light in series to one switch, or do I really have to run 5 separate + hot wires and ground to each individual light? Planning to use a SwitchPros unit most likely.

 

Each of those are rated for a combined 6.12A draw, so let’s just round that to 7A. If you use 5 of those, you’re at a 35A power draw. That is conveniently what a few of the SwitchPros circuits are rated for.

A key thing to keep in mind is wire gauge. For a run up to the roof from the engine compartment, you’re looking at 8awg (OFC) power and ground.

I might suggest something like this post, where he makes a junction box for power and ground distribution. Scroll to post #3497

Everyone is a newbie at one point! Electrical on your vehicle is no joke either! My suggestion, do a LOT of research and listen to what others have to say. I am in the process of designing and laying out my electrical upgrade and I will be making a fuse/relay panel with a high amperage main breaker to the fuse panel and using relays for all currents over a few amps to be safe and keep switches very low current. There is a great wealth of info so dig in and do it right the first time!

Enjoy!

 

So $2500 worth of lights and your hoping to save the $15 relays by daisy chaining them? I would be putting a relay on each light and linking the triggers instead.

Roof lights that big are going to be awkward- probably whistle like crazy sticking up off the Prinsu as well. Also as other poster have said running wire gauge big enough and long enough to get up there is going to be a pain. In the end it isn’t an ideal spot for big lights. 2 or 4 across the grill would be better, closer to the battery for wiring, and with much less glare off the hood.
