You are correct with almost all of the LED after market lights/aux lights on the market today.

LEDs are more of a point source of light than halogen, etc so the traditional reflector system does not work well at all for the. LEDs need sophisticated lens design in front of them to focus/manage the light correctly.

Most aftermarket people just buy the LED chip assembly, stick it in a more or less traditional housing/reflector and sell it.
A couple have added some poorly design cheapo lens to help a bit. they can get away with this because < at least in the US, there is essentially no law enforcement of aux light beam pattens. Head lights have clear beam pattern defiitnition to be legal...so the car and motorcycle manufactures must pay close attention

I don't know of any one in the motorcycle industry that has properly design an LED head light system. Looking at the pictures of the new GS, it may be the first....just don't know yet. I hope bmw gets it right


sooner or later some LED aux light producer will take the time and spend the design money to get the aux light beam patterns up to snuff....and make the LED light much better than they are now.

I mention that, because LED lights tend to have a poor projection pattern, with too much light spilling out a very wide angle onto road & objects very close [actually uselessly close for riding purposes] to the bike.
This reduces the effectiveness of the illumination of the distant road ~ but yet giving the psychological impression of greater overall brightness.

Don't confuse spot/fog lights with a proper led headlight. In Europe anyway the lights will have to focus the same as any other headlight. I imagine the same is true in the states since they have just been approved. By the looks of the low beam light the led is attached to the bar in front and shining backwards onto the reflector that will focus it. The high beam has several led sources that look like mini projectors. Maybe these focus onto different places to fill the road better?

Yep, firing the LED back into a properly define reflector make sense too....the key is to properly desing the LED lens/reflector to make the most of the quite different characteristics of LEDs vs the various incandescent light source.

Surefire - makes flashlights that produce in excess of 800 Lumens and they project well enough to identify a man in camouflage at 500 meters - and more. They are rugged enough to withstand the recoil of any automatic weapon made - M2, M240, 25MM canon, etc. The reflectors are designed and set at the factory and are pre-focused. The technology is there.

I recently purchased a set of the new PIAA LED driving Lights and they are both bright and illuminate fairly well. They could be better however. The LED is mounted on a cross bar and is directed into the reflector.

Absolutely, there are definitely good LED products out there but unfortunately there are a lot of bad ones too. There is also a lot of cheap ones out there where although the LED is actually quite reliable with a really good output the current regulator is absolute junk and they just don't last very long. You can get a single 3000 lumen Cree for about 5 bucks, it's the regulator that costs the money.

I spotted a new GS on the street in Basel, Switzerland

just after Thanksgiving.

It was parked among a few other bikes and scooters. November 27th, about 10PM. I could probably look at a map and figure out the address.

I did a double-take when I saw it. The spork was the giveaway.
I didnt think to take a picture with my phone.

Maybe I missed something earlier in the hundreds of pages of posts, but I was very surprised to see at as I did not think they were on the streets yet, even in Europe.

Does anyone know where the accessory socket lives on the GS LC? I looked for one on the bike at the San Mateo show but didn't see it.

There is one up near the windshield adjustment knob.

No picture? But not surprising they would have some test mules out on the road. Was it disguised at all? Rumor is that the WC GS has been tested for one million kilometers...so there are definitely bikes out there.

You'll see in one of my pictures as I post shortly

Long Beach, California Motorcycle Show pictures

LED lights with ignition off.


LED Daylight Running Lights on with the ignition on.


LED Low Beam (Left side) on (note that it does not stay on by default, you have to turn it on)


LED High Beam (Right side) on. It continues to keep low beam on.


New and improved side stand. It seems to me that the bike does not lean same or more than the current GS, perhaps less lean.


Oil filter


Brembo, front wheel


While BMW has replaced plastic oil reservoir mounted on the handlebar to aluminum, they seem to have kept this (next to the yellow shock thingy) as plastic.


Spoke wheel hub


Close up of the rim

More pictures of Long Beach, CA show

LED brake lights. These do not blink (DOT requirement). Notice that the yellow indicator lights (turn signals) have to be large as per DOT when the bike is delivered from the factory.


Standard turn signal for US market


BUT, I was told that you could replace it with LED (which may be brighter) as an option. I saw another bike that had the LED turn signals.


Tires. Your new WC GS will come with one of three different manufacturer tires. Not all bikes will come with Michelin tires as per Press Release. You would only know, when the crate is opened.


Raised GS logo (I am not sure if current GS has raised lettering)


Instrument cluster. It is showing "N" in LCD panel as well as coloured. However, if you change the gear, only the LCD panel will show the gear you are currently in. It was demonstrated to me by the rep.


Here you can see the accessory socket, below the windshield know and to the right of the panel.


Stock seat. It is not smooth, rather you can feel those slightly raised dots.


Exhaust


Miscellaneous pictures


I couldn't figure out the purpose of this plastic thing sticking out on the left side above the cylinder
