Premium Member Mr.Puss Posted February 6, 2016 Premium Member Share Posted February 6, 2016 Nice! Im still tempted to do this one too. Care to show us the wiring job on the backend?

alexm963 Posted February 8, 2016 Share Posted February 8, 2016 Aren't you going to burn up those first lights on each leg? Shouldn't they all be in parallel? Forgive me if I'm wrong, I'm in mechanical engineering not electrical. I'm guessing those leds are rated at 3v or so, supplying them with 12v won't make them last very long.

Premium Member Mr.Puss Posted February 8, 2016 Premium Member Share Posted February 8, 2016 Great! Thanks for taking the time to post this. Nice clean job too. Im a bit of a noob with this DIY lighting; what style/version of led did you use? Crush your enemies. See them driven before you. Hear the lamentations of their women. Fuss Life.

Damn...got to make it difficult for me now? This stuff is all "french" to me. Regardless, thanks for the insight. Looks like I have some homework to do. Crush your enemies.

alexm963 Posted February 9, 2016 Share Posted February 9, 2016 Ok I talked to one of the engineers at work that knows electrical better than anyone else here. You should be fine with that set up assuming those have a forward voltage drop less than 3V. That will be v_f on their data sheets. Most LEDs are 2-2.5V so I'm thinking no worries.

Global Moderator sorkyah Posted February 9, 2016 Global Moderator Share Posted February 9, 2016 Has any one hooked up a motto dynamics tail light and blinkers? I just made these and I wanna hook em up. I have mine setup with the motodynamics taillamp made a splitter harness and used stock connectors for my set i think motodynamic sells the harness too if im not mistaken made install really easy im going to make another set to clean up wiring and all that... first go around i didnt know much about electrical and it looked like shit @alexm963 those are in parallel the anode where he has his 'red' wire connected is just a bridge to the next The ground being at the othwr end is what will take the brunt of the current flow, im assuming thats a 65 ohm resistor under that heatshrink? He has them wired just fine ATGATT... ATTATT, two acronyms I live by. Link to comment Share on other sites More sharing options...
churchxd Posted February 9, 2016 Author Share Posted February 9, 2016 My leds have a fv of 2.5 and a 70mA rating. So if I did my calculations correctly I have 4 leds in a series (12v-10v)/.07=28.5ohm. And 3 sets of that in parallel so 28.5X3=85.5 ohm resistor to make my leds happy? Haha I'm a nub at this so call me out if I'm wrong Link to comment Share on other sites More sharing options...
Global Moderator sorkyah Posted February 9, 2016 Global Moderator Share Posted February 9, 2016 Running voltage can be anywhere from 12.8v to 14v depending on rpm 2.5V@ 70mA? What leds are you running? Set of whites for drls i got were 2.5@28 And the ambers for my signals were 3.5@60 Those have gotta be some bright leds ATGATT... ATTATT, two acronyms I live by.

bigity Posted February 9, 2016 Share Posted February 9, 2016 Well, I don't have a motodynamnics, but I did do these turn signals a la wickedtwisters design and I just use it with the original brake light. I had someone follow me to make sure it was visible and it works great. Originally, I had the LED's evenly spaced as above but I then moved the LED's medially so they would be more visible. As they move more medially, they are rotated done on the curvature and shine more out, instead of down. I had moto dynamics on another bike and found it to be much less safe and less visible. The difference between the running light and brake light is very small and can lead to people not recognizing your braking during the day.

For the whole thing. :confused: Link to comment Share on other sites More sharing options...
churchxd Posted February 10, 2016 Author Share Posted February 10, 2016 I would make it at least 3/4 watt resistor Link to comment Share on other sites More sharing options...

dpc46 Posted February 10, 2016 Share Posted February 10, 2016 And did you just drill a hole then hot glue the led in place? Link to comment Share on other sites More sharing options...
churchxd Posted February 10, 2016 Author Share Posted February 10, 2016 And did you just drill a hole then hot glue the led in place? I measured them out, and used a 4mm drill bit. Highly recommend center poping for the drill. I used a drop of super glue just to hold them in place while I wired them. And then I hot glued. I think the whole thing cost me 25 bucks Link to comment Share on other sites More sharing options...
dpc46 Posted February 10, 2016 Share Posted February 10, 2016 I never thought of running LEDs in that rear location. I think it's a great idea. I wanted to just remove my blinkers and not run any but this is sleek way of hiding it. Have you thought of a way to run the fronts? Link to comment Share on other sites More sharing options...
churchxd Posted February 10, 2016 Author Share Posted February 10, 2016 It actually started by another member just making it my own style. Um I think I'm going to do a flush mount r1 blinker tell I think of some something Link to comment Share on other sites More sharing options...

dpc46 Posted February 10, 2016 Share Posted February 10, 2016 That looks amazing. I'm think I might have to order up some LEDs myself. Link to comment Share on other sites More sharing options...
