lighting

I want to mount pod lights up front instead of a bar. How many would be traditional? I’m a truck driver and in that world all front or rear lights should be grouped in odd numbers. But I notice that pod light packs come in even numbered groups (4, 8, 20) is the grouping traditionally even...

Hey i was just wondering what all do i need to install an led bar on my commander, i have the bar and just ordered a switch for it but i was wondering if i need a relay or something and where do i run the wires to? Thanks
