Sorry guys, I know this may be a silly question. I am installed a lightbar. I have two sitch inputs, the High beam and a physical switch. Can someone tell me if the diagram I have is right??

Assuming you are using 30 and 87 of each relay and you only want the light bar on when both criteria are met, High beam on and switch on, then yes your diagram is correct.

Yep that is correct "I am an idiot". I want High beam on and Switch on to activate the light.

Have added the numbers now.... so this should work?posted_image

tonanzith. Pretty sure your way the switch trigger will turn the lights on without the other trigger. I need but relay to be activated for the light to work. So highbeam on and switch on.

Thanks though

No. See my above post for wiring relays. This will achieve turning on led when high beams are on or when you turn on the switch.

Ok. So you want the led to only turn on if BOTH the high beam and switch are on at the same time? If so I musunderstood.

If that's the case then yes your relay diagram will work. Sorry for misunderstanding.
