We choose the nilight 52 300w spot and flood combination led light bar because it has both spot and flood lenses in one bar was affordable and had decent reviews on amazon.
How to wire a roof mounted light bar.
I need to run wiring to the roof for my 40 led light bar 3 x led camping floods and a cigarette lighter accessory outlet for the roof top tent.
I think they are to high and will get caught on trees and what not and get damaged.
Make a connection between the light and the relay switch.
I m not a fan at all of the roof mounted light bars.
Once it is in the snorkel head the cable will run down into the dirty side of the airbox and will require drilling through the side of the airbox to penetrate the wiring back into the engine bay.
This was my midsize.
For safety purpose wrap the soldering portion with electrical tape.
I go though every step so.
After installing my a pillar mounted police light i m fully aware of just how full the a pillars are.
Now comes the critical part.
The switch will maintain the flow of current on the light bars.
The rest of the holes i had welded up.
Although not commonly adopted it is possible to loop the wire from a roof light bar into the back of the snorkel head.
This is the best method because it is the shortest distance for the wire to travel and it has the least chance of getting smashed in your door jamb.
Take the red wire of the light and join it with the red wire of the switch.
Of course using that type of wire gives you 3 wires so i paired up a couple of glands on the rear of the roof where the port installed roof rack went.
When having the roof rack installed we added a front 3 slat cross member so that we could mount a light bar it was a 65 addition.
I had a 30 inch across the hood.
Also like you stated height becomes an issue when in the garage.
The joining can be done by soldering.
By the way i like the location on the rear because it is easy to run the wire up to the roof by just dropping the rear section of the headliner.
