BMW R1200RT/R1250RT Forum

Hi,

First time posting here so I'll give you the background.

Havent been biking long, just over 2 years and long story short, I've picked up a 2009 ex Sussex police r1200rt with a full history.... And I'm chuffed with it. What a machine!!

My looking to keep the crash bars and hook up some Wunderlich aux lights to them and then use a left over light switch (currently has no function at all) to power it.

Do I need some sort of canbus fuse box or can they be hard wired onto the bike? I've been pointed in the direction of the canbus fuse box on nippy Normans but at £130 on top of the lights, it's making it a little too expensive.

Can anyone help!?

That's the programmable electronic fuse box at £130, you could use the one that takes ordinary fuses at £70 which is what I use...here 

Have a look at the Tour De France currently on everyday on ITV 4.  There are lots of RTs being used on that.  You will have no problem spotting them. With two dipped lights on all the time, and they are always high, there is absolutely no need for auxiliary lights on them.  Think of all the fuel you can buy with the saving.

Use an inline fuse and connect straight onto the battery. Simples.

What about canbus?

Going straight from the battery through an inline fuse and switch bypasses the canbus. You would have to remember to switch aux lights off when switching ignition off thats all.

Add a relay and you won't have to remember to turn off the lights.
The wiring is easy run one wire from the license plate lamp wire to the switch. The other wire from the switch goes to the control side of the relay. The other side of the control goes to ground. That completes the first circuit. Run a wire from the hot side of the battery to the switched portion of the relay and from the other contact to the lights.
