Hi all,

A question for the electrical guru's out there, I have done a bit of searching through the threads but can't find anything that answers my question.

I have 2 10 watt LED lights 1 spot and 1 fog, I want to run the fog with the dipped beam and the spot with the high beam. I have the dipped and high beam wired so that both stay on when on high.

Can I simply tap into the feed from each of the bikes lights and use a common ground for the aux lights?

Hopefully this will make sense to someone

Cheers

Paul

In theory that would work fine. Two 10W LED auxilliary lights will draw about 1.5A, so they could quite feasibly be tapped directly into the feeds to the high and low bulb holders and use a common earth. However, it would be better practice to use the tapped feed to trigger a relay (or two) and run a fused supply direct from the battery to the lights via the relay. This obviously involves more wiring time and you've got one (or two) relays, plus fuses to stash somewhere.

There are many ways to skin a cat though! A lot depends on how fussy you are about things?

Do you intend fitting any switches to the auxilliary lights so they can be isolated/turned off?

Thanks for the reply, I was thinking of running wiring and relays from the battery, in all honesty I was just looking for an easy way out I do intend to switch them as I believe it's a legal requirement here in Victoria. I think I can use a 3 pole toggle switch to have fog on, both on or all off. Would that be possible?

Yes that would work. A standard 3 position toggle lighting switch (off-side-head) will do the job for you.
