P700m2 18w work lights?

[sek-hunter]

I am gonna install a couple of 18W 4" lights on the back of my P2. I don't have to run these with relays do I? Just an inline fuse? What size fuse?

No relay necessary, if you run off of reverse switch then I would. 5amp fuse should be about right.

I don't run a relay with any of my LED lights. @CumminsPusher taught me you divide watts by volts to get the correct fuse size.

So two 18w lights is 36w/12 volts = 3 amp fuse.

Did I get it right CP?

Dang you beat me to the punch!

That is the right way to calculate amps. Just remember that if you are running 3 amps all the time, on a 3 amp fuse, you will likely get nuisance tripping. By going up to a 5 amp fuse, you won't be on the ragged edge of burning the fuse all the time.

It's called Ohm's law for reference.
