My Honda ST1100 had beautiful 3-wire turn signals (1157 socket) which meant that the turn signals could function as both ‘running lights’ and as ‘turn signals’.
This might not seem like a big deal, but on a 2-wheeler where you want to be seen as much as possible, having those running lights can be a huge visibility boost. My V-Strom unfortunately has a 2-wire (1156 socket) system meaning turn signals only blink when I activate the turn signal, and stays turned off at all other times…. this bothered me a lot.
The beautiful final result! (I’ve also added LED light strips on the handguards)

This 1980 detailed article shows that having headlights (a proxy for lighting/visibility) OFF increased the chance of an accident by more than a factor of 2 ! Also, the oncoming automobile driver ‘not seeing’ the motorcycle is the biggest reason for accidents. Visibility is hugely important! Think about that….a simple lighting improvement reduces accident likelihood by more than 50%.. (page 387 in this document)
To come back to the my V-Strom, I decided to modify the stock wiring to use the Custom Dynamics turn signal module to convert my turn signals into turn + running lights.
You need the Custom Dynamics blinker module, $30 shipped. You get two modules for the $30
I also bought a set of posi tap & posi lock connections to help me with tapping into stock wiring with minimal splice / cutting / soldering.
On the V-Strom, the left and right turn bulbs each have two wires. You can visually inspect them by looking into the front fairing, to the sides of the headlights.
Right side – Green wire (blinker) and B/W (ground)
Left side – Solid black wire (blinker) and B/W (ground)
The writing is pretty straightforward with the posi tap products. You can disconnect the connections between each turn wire (see the marked picture) and then use one blinker set for each side.
Wiring information for blinker module:-
Once the wiring is correctly done, just test it out to make sure things are working correctly. Once this final check is done, you can now go ahead and safely tuck away the wiring neatly with zip ties inside the fairing. MAKE SURE YOU CAN TURN HANDLEBARS WITHOUT DAMAGING WIRING !
Hope this helps anyone trying to get running and turn lights on their motorcycle. This works for any motorcycle with the two wire situation.
