Bicycle Turn & Stop Signals
3D Printed Parts for Bicycle Turn and Stop Signals with Front and Rear Lights 1.2 (2019-09-06)  

3D Printed Bicycle Turn and Stop Signals. file size: ~10MB

Below you will find parts and tools, which will help you to add turn and stop signals to your bicycle. Not all tools, like multimeter or label printer, are necessary. If you noticed mistakes, have questions or suggestions, know better component (available in EU and US), please write or send link to • Bicylce on

Parts were printed from PETG with Prusa3D i3 MK3 Printer. If your printer is not precise enough, printed parts may not fit into each other and may not look good. Spaces between some parts are 0.1mm only.

This project is based on 12 Volts. Bicycle dynamos and lights are, usually, 6 Volts. USB is 5 Volts. Be careful and don't mix wires.

If you made your own updates or (file) changes, related to this project, please send me a link. I will add this link to your work on this page.

LUYED (China) 1157 3014 78-EX red LED bulb: Brighter than OSRAM LED bulb. All LED chips are shining in “tail only” mode. When you press brake lever (enable “stop” mode), all LED chips become slightly brighter. Difference between “tail only” and “stop” mode is minimal and not very distinguishable. You can increased difference between “tail only” and “stop” modes by dimming tail light slightly with 1 kΩ potentiometer.

OSRAM (Germany) 1457R red LED bulb: Only 6 LED chips are shining in “tail only” mode. When you press brake lever (enable “stop” mode), another 12 LED chips start to shine. Not as bright as LUYED bulb in both modes, but difference between “tail only” and “stop” modes is more distinguishable without dimming tail light with 1 kΩ potentiometer. Currently I prefer LUYED with 1 kΩ potentiometer setup.

NiceLite LED Cycle Dynamo Bulbs

2017-01Busch + MüllerDymotec 6 Dynamo€32

High output tyre dynamo (6 volt, 3 watt) with approx. 40 % efficiency. The position to the tyre as well as the contact pressure can be aligned perfectly with two easy adjustments. With easy touch trigger: a quick press of the finger suffices, and the dynamo pivots toward the tyre. Less expensive than Dymotec S12 (12V, 6.2W). Available for either right or left side mounting. Dymotec 6 can power Halogen or LED bulbs:

2.4W / 6V (headlight) + 0.6W / 6V (taillight) bulb. Total: 3W.


3W / 6V single (headlight) bub.

• 6 Volt / 3 Watt
• Unique efficiency: approx. 40%
• Position and contact pressure adjustable
• Separate versions for mounting to the left or right of the bicycle

A special separate roller with high alloyed steel brushes is available for temporary use under extreme conditions. During rain, slush, snow or ice it works with optimised contact pressure and maximal traction – gentle to the tyre and self-cleaning.

Dynamo Power

2017-01Busch + MüllerE-Werk €95

Power without mains
For all those that do not want to do without mobile phone, GPS, MP3 player or other electronic devices while cycling, Busch & Müller has developed the bike-mobile E-WERK. Connected to a hub dynamo; the energy is made useable to charge and/or power mobile devices.

• Voltage and current adjustable
• Universal connections (e.g. USB)
• Extensive accessories
• Splash- and rainwater-proof

Universally usable
With this dynamo-connected, universal powering device, voltage (up to 13.3 V) and current (up to 1.5 A) can be adjusted variably in small increments. It charges at velocities of approx. 8 km/h and faster. At only 15 km/h it charges as quickly as standard mains connected chargers. It can be fed with up to 50 V DC, so that operation with an e-bike or car battery is possible as well.

Connection options of the E-WERK
Universal connections for USB, Mini USB, Micro USB. 2 free cables for individual connections. With special plugs for SON and Shimano hub dynamos. Watertight cable screw joints.

2018-12Kester44 Flux-Cored Wire€25

Kester 44 Rosin Flux is an activated rosin formula for use in flux-cored solder wire. 44 has virtually dominated the field of activated rosin core solders for well over four decades. An outstanding performance feature of this flux is the “instant-action” wetting behavior. The high mobility and fast-spreading action of this flux results in more reliable production line soldering. 44 is classified as ROM1 per J-STD-004.

Sn60Pb40 - 0.8mm - 3.3% Flux - melting range 183-190°C
Sn63Pb37 - 0.8mm - 3.3% Flux - melting point 183°C

PrusaSlicer is available for Windows, Mac and Linux

• "Extruder: 220°C".
• "Bed: 80°C".

• "Fill density: 80%".

• "Ensure vertical shell thickness: disabled - I had problems with thin 45° hanging angles with this feature enabled.
• "Perimeters: 3" - infill pattern is less visible on surface.

• Below are modified "0.20mm QUALITY MK3" settings, oriented to reduce printing noise (slow printing speed). There are no violent vibrations with low speeds... this means lesser probability for corners of big parts to unstick from heated bed, because of shrinking.
• Exception is "Speed for non-print moves > travel: 180" - low speed, like 20, creates surface blobs after long travel distances.
• Exception is "First layer speed: 10" - for better adhesion.
• You can print (faster) with default-recommended speed settings. Slower speeds gives smoother and glossier surface without matte areas.

• I added few lines to G-code to solve problems with filament blob on nozzle and intro line wearing surface of steel sheet plate.

G1 Z50 ; ADDED LINE --- Z Up to clean filament blob from nozzle
G1 Z-50 ; ADDED LINE --- Z Down
G1 Z0.50 ; ADDED LINE --- Z Up for less intro line adhesion to prevent surface of steel sheet plate from wearing
