DIY: How to create Daytime Running Lights on a 2 wire system
Hi Guys,
I was going to make a kit for this, but it's just too much work for me considering the other things going on. I've drawn a diagram that should be easy to follow and will post some pics of the actual unit I made. I made this kit to be plug and play with OEM connectors (of course I did). However, you can use wire taps, although it's a more permanent solution. What the kit does is tap power off the license plate lights and steps the voltage down to ~9.5v. This illuminates the blinkers, but not at full power. When you flip the blinker on, it gets full power and "blinks." You can see this in the video. It works on both LED and standard bulbs. Actually, the kit makes more of a difference with the standard bulb since it draws more power to light. I don't have video of that, but I did test it out. The beauty of this is that it will work on any bike with only 2 wires for the blinkers. Please note: The diagram is only for 1 blinker. In the pics, you'll see I made two of them on a project "prototyping" board. I think with the LED's, you can get away with only using 1, but you may want 2 if you are using OEM/standard bulbs. Using 2 does cut down on how much heat the resistors will generate though. I should also add that if you install this on a bike with standard bulbs, you will need to have the bike running in order to test the kit out. Otherwise, it looks like it's not working. Too much power draw for standard bulbs without having the bike's stator not giving max power. Here are the components (x2 if you make a unit with 2): LM317T Adjustable voltage regulator 1k ohm (1/4 or 1/2 watt) Resistor 150 ohm (1/4 or 1/2 watt) Resistor 1 diode- it can be a1N4001 1 prototype board- I used this and trimmed it to fit inside my project box. ~7' 18-22ga of black and red wire each Project box to house the unit Soldering iron and solder

Interesting way to do it. Is there any way to get a little more contrast between 'running' and 'turning'? I used relays so I have on vs off, but that means that my fronts and rears alternate instead of blinking together.
Definitely interested in what you did here. |

Yeah, just drop the voltage down. Replace the R1 (150ohm) to 240 Ohm and it will output 6.458V. That will dim down the lights and provide a greater contrast.
Here's a calculator to play with output voltages: http://diyaudioprojects.com/Technica...age-Regulator/ Just keep in mind, you will need to use a value that is actually produced as a resistor. Just because you want to use 175 ohms doesn't mean it exists, or it may be really expensive.

Thanks for the link! Yeah I can make combinations of resistors for that.
