LED Headlight Upgrade for Hyperstrada 939

Hi everyone, and thank you for the help I've received on this forum - it's really appreciated.

I have a 2016 Hyperstrada 939 and recently had my first after dark ride on a road without street lights. I found it scary how lousy the standard headlight is, particularly on low beam! I really need to improve the light it puts out.

I could replace the halogen globe for an LED version, but I've read about the beam coverage changing because of the light source being in a different location in the reflector. Anyone tried this, was it worth it, and did you need to modify anything?

I've seen adverts for LED headlights such as the one from Hoglights where the entire headlight is replaced. Are these significantly better than standard?

And finally am I better off adding auxiliary lights such as Denali D3s?

Supplementary question: I've read that this bike has CANBUS but I've also read that CANBUS eliminates the need for fuses. Since my bike has fuses, does that mean that it doesn't actually use CANBUS?

Verify that your low beam isn't burnt out. I bought my bike used and i had to replace the bulb as the LED accent lights hid the fact that the bulb's low beam element was burnt out.

Yes, changing from halogen to LED in a fixture designed for halogen isn't the best solution. Buy a set of quality aux lights if you do a lot of night riding. I have replaced headlight assemblies on other bikes but have no experience with the manufacturer you mentioned. I have found that a set of aux lights far outperforms a single replacement.

This is from the 2016 maintenance manual.

CAN line
This model utilises a CAN line (Controller Area Network) which has made it possible to greatly simplify the layout of
the electrical system and consequently reduce its overall weight.
The CAN line is connected to two nodes: the instrument panel and the engine control unit. Thanks to this
communication line no sensor doubles are required as sensor signals are shared by both electronic units. Sensors
are connected to closer electronic unit (instrument panel or engine control unit), which sends the signals to the
network to be processed by the control units.
CAN line consists of two wires for digital signal transfer; they both carry precise and perfectly decipherable data.
The instrument panel and the engine control unit, which are connected to the CAN line, are fitted with special
hardware which acknowledges whether a pulse sequence includes pertaining data to be processed by the
computing unit.

Here's a couple threads which may offer addtional info.

LED bulbs can work well in headlights designed for halogen, but only if the LED designer has that as a priority. Look for two (only) faces to the emitter carrier, which should be as slim as possible. Also, the LED bulb will need to be able to be twisted in it's socket to adjust for the best-possible beam pattern. My recommendation has always been for Auxito brand, but there may be others that work as well now. Check that the electronic driver (which may now be integral to the bulb rather than separate) can handle canbus electrics too.

I use this LED lamp. Plug and play.

Also using spot light for low and high beam
The spot light for high beam helps a lot.

Thanks Stefan,

Does the H4 globe change the light pattern? I've heard that many LED replacement globes need shimming to adjust their position in the reflector.

Those auxiliary lights - what are they? Did you make the brackets yourself? How complicated is the harness? Switch on the handlebars or integrated into the existing low/high beam wiring?

Looks great by the way!

Hi Frantic

Same pattern as the halogen bulb.

Made the bracket by myself.
Bought the spot lights at eBay/Amazon.
The high beam has 4 leds, total 20 watts, and has 3000 lumen each. Connected to a relay.
The DRL has 1 led and is 10 watt. Connected to aux output just below the saddle.

Just a plea from a fellow road-user, two-wheeled and four.

Please don't ride with all your spotlights and high-beam full on in the daytime! That amount of illumination really isn't necessary for you to be seen, and it means other road-users can't afford to look at you to gauge your speed and distance without being thoroughly blinded. We are touring in Scotland at the moment in a camper-van, and bikers who ride with their lights full on, especially BMW GS riders of course, are a real pain.

I have changed the halogen bulb for a LED bulb, from Osram.

It was very better. But I still wanted some focal long range lights. So I installed two LED headlights there(see the photos):
