My $18 led integrator

[InfiniteReality]

I made my UFO undertail taillight with 122 red 20000mcd LEDs.  Everything works 100% on it, BUT it's hard as hell to find a LED integrator so you can combine your brake lights and signals like I want.  I don't know if anyone else has tried to find one of these things, but VERY few companies make them.  I actually had a BadLands one on order from Dennis Kirk and they called to tell me that they won't be available till mid June, so I told them to cancel the order.  Not to mention it costs $100 for one versus $11 for a typical trailer integrator from Wal-Mart.  
So I got to thinking on alternate ways to do this.  I knew I could do it solid state with relays, just didn't know how many it would take.  I figured out the schematic on it and kept having to use 6 standard automotive SPDT relays.  After racking my brain for an hour, I finally figured out how to do it with only 4.  

Here's 2 links to relays and sockets for them to do it at only a cost of $18!

Below is the schematic I drew of how to wire a set together for one side of your brake light.  Just repeat it for the other side.  This will work with LEDs AND it will work with regular incadescent bulbs so if you ever swap to LED bulbs later it'll still work properly

cool beans

Yep and it'll work with anyone else that has LED taillights and want to integrate them.

can you show pics of how you did this along with explanation on the schematic for those unfamiliar with reading a wiring schematic?

I doubt it since it's been 5 months since he logged in.....

Nice DYI, but I bought one from U-Haul for $16 when I did mine.

my buddy is gonna help me do mine with the resistors......my cost? 0$. he had 4 of the resistors n sockets layin around he never used. BONUS!

i did this mod over the weekend. the final result is as advertised, but there seems to be voltage finding it's way bac to the other side for a fraction of a second. when the right or left turn is blinking, the other side blinks a little bit too. also, when i apply the brakes, both flash really quickly. does anyone else have any information?

I did the same as Dennis. Works great for less than 20 bucks.

I saw some of that too, until I put the resistors in to bring the flash rate back to normal. The integrator is designed to work with the resitance filament bulbs, so I guess it feeds back a little with just the LEDs.

wish there was a way to make it such that when you put on say, the right signal, both the right signal/brake leds blink as well as the right side running light to make the signal more profound

I did the same thing to mine..if I have the turn on..and hit the brakes..they blink super fast..
