Need help with Wiring/Math Hellas & LED's

So this may be a stupid questions but here goes...

I recently got a plate bumper and the stock fogs were replaced with Blitzpro 3inch LED pods.

Also have some 7inch Hellas with HID's.

So...

The LED's are 12Watt and the HID's are 35Watt.

So according to the internet A=W/V so the total of both units Amp draw is

A= 12/12
A= 35/12

Which comes to ~3.91 Amps (Someone please correct me if I am wrong)

If I were to hook up both light systems to the stock wiring harness/OEM fog switch would everything work fine? Will I melt wires?

I do plan on adding a HID harness soon, just don't have one yet.

Or what would be the best way to hookup both sets to a single switch with minimal additional wiring? I am ok with running electrical stuff, but was never too good with calculating what fuses/relays I need... Thanks in advance hope it makes sense to someone who can help.

Also these will obviously not be on all the time, but will be put to use at night/dark areas.

I'm not sure of actual numbers, but the reason HIDs require a harness is because of the inrush when they are warming up. Once up to temp, they draw a small amount of current. That's the number you need to factor into your amperage being placed on factory wires.

12W + 35W = 47W
47W * 2 = 94W = 7.8333 Amps
I'm running a pair of 55W H10 bulbs in my stock fogs with no problems
55W * 2 = 110W = 9.1666 Amps
