Installing Switched Driving Lights on the 1050XT

Having said what I said in my previous message I have to say I did recently add auxiliary lights to my DL1050XA.

I didn't add them for more lights or any of the common excuses for adding more lights.

Many modern cars have standard LED headlights. From what I have heard these don't have replaceable bulbs. The LED is part of the circuit board. In the rare chance they burn out you replace the motherboard.

My understanding of my DL1050 is the "bulbs" are not replaceable. If the headlight burnt out what do you think that a local dealer would have the part in stock or even in the country?

I added the auxiliary lights to act as backup lights. Since I have then I might run them sometimes just because and the way I have mounted the switch it is quite possible I accidentally turn them on but I am sure I would notice that as the sunlight dims.


The main reason is just in case something happens to my main light.

(Not to temp fate but with over 91,000 km / 56,500+ miles the stock ones have been totally reliable.)

Today my Denali lights arrived. But the auto dimmer unit has still yet to arrive.

So, I've started by mounting the lights on the engine bars and routing the cables to where they'll eventually live.

The setup which I'm going for will have a "dimmable" relay installed. But it needs to be connected to the high beam (or "brights"). I've looked at the headlight/dash assembly and it's a rather daunting prospect to dismantle so I can tap into the high beam wire.

So, I thought, "does it have a relay". Turned on the ignition, not the engine, then flicked the high/low beam switch. Sure enough, there is a relay clicking somewhere under the seat. I've removed the plastic cover (the cigarette lighter socket is a part of it), then I had to go out. So I've gotten no further.

Meanwhile I'm trying to find info on this relay as there are a few things with lots of wires coming out of them under that tray.

Just wondering if anyone has done a project like this and if so, how'd you go about getting to the high beam circuit?

When I started this, I found the fuse box. It has fuses for high and low beam, but they aren't switched with the switch. They have constant power going TO the high/low beams. So I can't use that. I was going to use one of those piggyback fuse blocks but it won't fit, anyway.

I'm trying to do this with the least amount of dismantling/wire tapping/cutting/soldering as I can.

I'll get there.

How do,

I fitted Denali's to mine, using the Datadim.

The main relay is at the back of the bike.

Seat off, pop the grab handles/ top box rack off. Remove the plastic bodywork over rear light area. Remove the inner plastic trim (the one with the power socket in).

You're looking for the main body of the relay. Take your 12v switched from the Aux power socket wiring, & your main beam feed from the Yellow & Blue wire.

There was another thread on the forum where I posted the diagrams if that helps?

Great lights & with Datadim, effortlessly perfect 👌

Attached a few screen shots. The realay you're looking for is No.23 on the yellow picture. Hope they help.

I find the sides of the ditch don't light very well at all with the high beams. Even with lights properly adjusted. That blue and yellow wire is handy. On bottom of big plug in back.

Just tested new lights, night, then day! Dunno why anyone wouldn't add aux lights! Exceeds expectations.😃

Installation has been completed except for the "datadim" relay which is still to arrive. The yellow/blue wire was tapped into for the high-beam trigger, tested and works as expected. The high beam trigger wire is fused.

There is another trigger wire. This one turns the lights on and off with the ignition. I use a Healtech Thunderbox for its power source as it comes on and off with the engine.

When the relay comes and is installed, I'll put the fuses in, turn it on and hopefully the smoke within the electrical components stays there.

Then I can do final adjustments to the lights themselves. As you can see in Photo One, they're a bit cockeyed.

Photo Two shows the wiring layout under the seat. I'll tidy it up once the relay is in and mounted in position.

Photo Three shows the on/off switch which is double sided taped to the cowl next to the dash.

I just completed the same install, only with amazon.ca aux lights (cheapo's). I didn't want a switch, but rather full-time amber driving lights (conspicuity reasons & ditch lights) and then a switched high-beam with the stock high-beam switch. So far it works really great, and I am more than impressed with the improved quality of light. I had no criticisms over the stock, but wanted more conspicuity and for my area - the ability to illuminate to the sides of the road better.
After looking at the harness & install options, I tested the aux lights and found a 0.9A draw consistently. So, I used a fused switched connection for the low-beam, and tapped into the high-beam wire on the headlight unit to act as the trigger wire for the high-beam.
I made a simple bracket so that it installs on the stock lower crash bar using the existing rubber mount. We will see over time how it does in that position. Unfortunately I haven't taken a picture of the lights installled. Attached is the wiring diagram for my additional lights & fuse block.

The Datadim relay arrived today. Went out to the shed and plugged it in. Battery down in volts when I tried to start it.

Got it started. Tested the lights. Low beam, half intensity, high beam full intensity. Back to low beam, tested on/off switch. All good. Turned off bike. Lights stayed on. Hmmm.

Noticed that the power outlet and the Garmin Zumo XT which is fed from the Healtech Thunderbox were also on. The Denali lights are switched on/off via a white wire which requires a switched power supply, so I use the Thunderbox for that.

However, for some reason, the Thunderbox stays active after I turn the engine off if the Denalis are still on. When I switch them off via the pushbutton switch that comes with the kit, then the Thunderbox powers down to standby mode.

I left the Denalis switched off and started the bike. The Thunderbox performed normally. Powered up, got juice to the GPS, etc., then when I turned the bike off the Thunderbox went back to standby mode, as it should and power to the GPS, etc. was lost.

It must have been like this since yesterday when I finished wiring everything in, but the fuses for the Denalis were removed til I got the relay.

I can only guess at this, but something must be feeding back to the Thunderbox to keep it live.

I'll write to both Denali and Healtech to see if they have any answers. In the meantime I'll switch the lights off manually.

If they can't work something out for me then I'll look at powering the Denali switch wire from the taillight or maybe the aux power outlet under the seat which comes on and off with the ignition.

In the meantime I'll take the bike out for a run tonight to aim and test the lights.
