Vision X Optimus LED lamps - wiring conundrum

[vee5]

I've just bought a pair of Vision X Optimus long range LED spots from Adventure Spec for my 2010 1200GSA. These were supplied with a loom which was clearly designed as an entirely separate switched lighting circuit for a car, plus I've now decided I'd rather control these via the standard high beam switch rather than the supplied seperate switch.

Vision X wiring diagram is here:http://www.visionxusa.com/documents/PrimeDrive_Wiring.pdf (shows different lighting unit to the Optimus)

I'll mention straight away that wiring is largely a mystery to me, especially when it comes to canbus so I'm wondering if anyone has some clear advice on the best way to wire these into my canbus high beam circuit before I blunder onwards and completely fry various parts of my existing electics

The supplied loom has a fuse and relay (30, 85,86,87) and they have Deutsche connectors BTW.

Desperate to get these fitted ASAP whilst we've still got the dark weather !

A 20 amp fuse for the switch circuit is wat too much, also the wire gauge is too much.

A 2 amp or even less is good enough

I would have said 20 amp is too high a fuse for the LED but not sure of thie power requirement.

But remember. V* A = W

so volts you know at 12
W from the power requirements

This will give you the fuse rating required ang gauge of wire

Put wire gauge higher than its requirement

You won't be able to wire them directly as the Can Bus will have a spaz out.

You'll need to use the main beam circuit to switch a relay etc.

That's Can Bus for ya!!

I have vision x solstice on my gs but these are only 10 w each not sure about yours, I wired mine straight to my headlight, the extra 20w has not coursed a problem

Is it a 1200?

Thanks guys. The spots are 10w each, so if V*A=W and watts are 20 and volts 12 that gives approx 1.6 amps.
I think the canbus accessory socket will run 5 amps max (?) so that means I could run a a BMW splitter (http://www.ukgser.com/forums/showthread.php?t=180464 ) off an accessory socket to run the power to a relay and also split a feed off the high beam wire into the relay.

That would give me canbus friendly spots activated from the high beam switch by my (potentially misinformed) reasoning. But if I'm running the power from a canbus accessory socket do I even need a fuse, surely the canbus system should take care of any overload?

It is yes

You got it on one!

Although you'll need to run a fuse in.

Your lamps will draw 1.6 amps, the accessory socket is rated to 5 amps. You'll need to fuse the supply from the battery anyway then fuse the supply from the relay supply to the lights.

Bit confused (no pun intended) about needing TWO fuses - the feed from the battery will actually be taken directly from the canbus aux socket. I thought canbus was supposed to act a bit like a high tech fuse and automatically shut down any circuit drawing too much?

Apologies if I'm simply highlighting my pathetic knowledge of these matters but I would rather understand the wiring before I install it !

The aux socket is understandably designed to have a variable output which is limited to 5 amps. Therefore the aux socket could happily send 5 amps to your 1.6 amp lights - Hence the need for a fuse.

Thanks - funny the way previously mysterious concepts become so blindingly obvious once they are explained !

i also fitted a set of the optimus lights today. the loom is designed for baja trucks and the like, i hopped down to halfords and got some 5 amp wire and just copied the x vision one and ran it through the centec. you can also utilise the wire sleaving off the x vision loom so it all looks nice and neat. it is also a requirement to add a power lead from the switch.
