70mm BMW Illumindation "puck"

Update: Sine I could find no easy reliable way to controll the brightness of the “running light” mode on these I designed some light shrouds that cab snap on securly that then can be adusted to block the light from the rider. I designed these to be slightly smaller inner diamerter to they friction fit so they do not freely rotate, but can be rotated with some effort to be adjested for blocking the light depending on your seating position. I would print these in either PETG or ASA (Which is what I used - ASA) they should hold up without breaking. The fit very tight so care should be taken not to damage the clear “lense” but the lenses are thick enough to support the presure fit of the shroud. There is a left and right but they are basicly the same, you could print two of either and use them for the same on both sides.

For my 2013 BMW R1250GS Adventure I wanted to add illumination “pucks” to the side of the bike where the BMW emblems are. So I designed and build these uing readaly avaiable LED strips from Amazon. If you decide to print these here is what I used for filiment and printer.

Bambu Lab P1S (With AMS), Translusent white PETG filment, for the main body of the puck, black ASA filment for the back cover.

The LED strips have to be removed from the orignal housings, and then solderd together (I made sure the LED's that are sequnsual were going the same direction, but you could have them going the reverse. These led strips are “switchback” style so they are a while running light in normal mode and when the turn indicator comes on the switch to seqensual then back to white when the turn signal is canceled.

Since these will be exposed to the elements, you will want to seal the enclosture with silicone to make a waterproof seal. The silicone acts as the glue that hold the “puck” together. You will want to seal the hold also for the wire.

Wiring will be up to you but you can get a wire signal from the factor signals and it will not interfear with the computer. But on my 23 R1250GS the front signals are two wire and are low current (dim) when in running light mode, and higer current in turn mode (bright), so you would NOT be able to use the fromt lights as a trigger for these LED strips. You would have to get a trigger from the rear turn signals (as I did).

The running light will have to be an ignition on wire, and then you need a ground.
