Any way to wire it so that there are still running lights? Some how split the circuit board up to where when you turn the lights on the only the outside ring (or top & bottom three) LED's lights up, and when you allpy the brakes all LED's Light up? Any further news in this? I have seen LED light sets for old Ford Trucks on "Truckin" so this can't be to hard to figure out. |

im thinking of engineering a set of these, but have an actual etched circuit board made because i work making PCBs... a simple led array with a couple of resistors it seems.. |

I would be interested in a set for my snowflake lights. My '59 Rag is a beater/driver, so any help I can get to light up my life is great. The current lights are bright, but brighter is better--I run without the diffuser.
12 volt alternator, if that matters. I'd like the running lights, brake lights and turn signals to all be in one snowflake housing. Awesome.
Also, I need to wire up the little bulb holder on the bottom of the headlamp to be a turn signal. Anyone doing anything that will make that super-bright? I do have lows and brights for my headlights, but it doesn't make much of a difference. Anyone adapting anything for the front to make it brighter?
I'm a plug-and-play guy. I'm sort of handy, but have enough projects to keep me out of the garage for the next bit--new wife, middle of school, running a full time high school ministry--you know, all the normal stuff, but I want my driver to be my driver and not as much of an obsession...though here I am, after reading about 1,000 posts this morning. I'm supposed to be translasting a bit of Philipians out of the the Greek right now...
Thanks,
Dave |

OK so today I finally started putting together the leds with the array made by ninamashr.
however, I was slightly dissapointed that the results I achieved fell a bit short of ninamashr's youtube video. after a bit of pondering I realized it was b/c my car is 12 volt . I realized that my leds are just as bright, but my regular bulb is much brighter, thereby drowning out the leds. I wired em up as running lights so they are a little more visible now. will take more pix once it is dark _________________ MAIMAS... read it backwards

I was thinking about this last night, even thoug I am an electrical idiot I think I could accually do this. I can get the LED's for about 0.50 each(3mm) or the 5mm for about 0.90 each. Now my question is what resistor do I need? I know radio shack has resistors, just need the code or Ohm rating. go easy on me here. _________________ Cheap, Fast, Reliable; pick two! |

I made the mistake of thinking there were 6.1 volts going to the brake light and there were actually only 4.9 volts. So my led's started working erractically. I would suggest you check how many volts are actually going to the brakelights BEFORE designing and soldering your array. I went here to design my array...
http://led.linear1.org/led.wiz
I am using 13 ea - 5mm Red led's, the resistor will depend on the actual source voltage going to the array. The "diode forward voltage" will be 2.0 for red led's, the "diode forward current (mA)" generally should be 20 mA. |

yah i saw those in hotvws, they are AMAZING, would run them in a heartbeat if i had those taillights _________________ MAIMAS... read it backwards

Should I use red or white leds for these? |

You want to use red LEDs in order to utilize their full intensity.
White LEDs work by mixing narrow bandwidth peaks of red, green, and blue emissions. The red taillight lens will filter out the green and blue components, giving you roughly 1/3 the intensity spec for the LED. _________________ Evan H.
