24 5mm LEDs in clear side marker/turn signal!

To answer you question “TrueG” the LED specs are: 5mm/ 3.3 volts / 20ma/ I wire 3 LEDS in series then used a 220 ohm resister for each set of 3…I originally said I used 24 LEDs…I for got I added 1 more to the very front of the lens so I had to use a 560 ohm resistor for that…see this site for help with wiring LEDs in series http://www.casemodgod.com/led_calculator.htm I then dremeled out the back of the lens and used a blank circuit board purchased from radio shack, this particular circuit board is perfect because it has tiny holes which line up perfect with the LEDs pigtails. I then cut the board match the lens housing and individually place each led in line then wired everything up. I used a two part resin to seal everything up. Now in order for the Lens to fit back into it’s location you would have to deepen the opening because the wiring and Resin from the setup is deeper than the stock Lens case. I could have installed LEDs to fill the lens but space was an issue> I thinks it’s fine the way it is.
Were they radio shack SPST relays or SPDT relays? Also I noticed in the video that the LED's appeared to have dimmed. Was that a camera effect due to light or did you actually dim them from somewhere. Sorry for all the q's but I want to do this mod!
Keep us posted on the rear LED retro as well! Have you also thought about adding puddle lights under the sills of the car that will illuminate when you open the door?

The relays purpose is to limit the draw of current on the front turn signal harness…I installed a higher voltage bulb to the side markers on my last vehicle and it melted the harness because it wasn’t intended to supply that amount of current. By using the relay you’re using the original side markers power to light the bulb and not adding extra load to the turn signal…also when wiring the way most peep here has done you’re essentially combining two positive wires which does not sound to safe to me because all that extra voltage has to go somewhere…there are some post which states that when doing this mod the old way it causes your rear side markers to illuminate when the hazards are on…not safe if all of these weird issues are happening see here… http://forums.freshalloy.com/ubbthre...=&fpart=2&vc=1
The relays used are standard 5 pin SPDT ‘s found in any auto parts store. In the video it appears my LEDs dimmed when I got closer, not the case, my digi cam has a function to auto correct white balance

What are the voltage ratings for the relays?
What is the wattage and tolerance values for the 220 resistors?
Is it a minirelay? Or an automotive relay? If it is a minirelay, do you have it on the circuit board or did you attach the wires directly onto the pins?

each white dot = LED
each green dot = 220 ohm resistor
as you can see every 3 led is wired in series. after ending up with 8 sets of 3 series wired led I then soldered all remaining negative leads from led to one another then soldered a 220ohm resistor to the remaining positive lead left over from the wired series...then combined all the positive from the resistors which left me with two left over wires..a positve and negative which is used to send power to the LEDs
