LED worklights, would you wire via a relay?

Two LED work lights (18w) would draw around three amps. If I am running a fused feed to the dash and then out to the rear of my 110 would I need to worry about a relay? I don't want them ignition switched.

Thanks,

James

Less than 3A draw at 18w more like 1.2A - 1.6A.
I presume you mean a pair through.

Most switches are rated at 6A minimum but should be fine directly switched, but a relay would do no harm either.

I wouldn't worry about it, unless using a relay gives you some other sort of benefit that's useful to you like changing from high to low side switching, or control from something else.

I have some changeover switches inside my rear door that switch the worklight and a 12V DIN socket on/off/remote. That means I can have the socket controlled from the dash switch, or the light controlled from the dash switch, or both, or either of them controlled locally. Most of the time I have the socket off and the worklight as remote, but if I wanted to put a beacon in temporarily then I could have the worklight manual and the beacon controlled from the dash for instance. Next step is to have a 12V socket that's on/off/ignition.

I love the idea of the 12 volt being on off ignition

It's not that hard, you just need two feeds in to a changeover switch.
