Wattage Rating ???

[Tigger]

I have got myself a set of new bulbs for my full beam
They are the Halfrauds Rally ones (red box; 80w)

On the back of the box it says
"Check vehicle wiring and switches before installing high wattage bulbs. They must be rated at 20amps for 100w bulbs at 12v"

How do I check this?

Cheers

Easy way it to check the fuse on your main hedlinght bulbs see if its less than 20 amp.

Anyway its 20amp for 100w you have 80 watt bulbs so its less.

power = voltage * current so.

current = power / voltage
