I searched everywhere about making your own led lights but didnt find much. So if anyone has the interest in doing this follow along. I used info from this site http://www.sca40.com/led/ which you should look at to understand the math needed to determine how to design your light and to work up a parts list. I basically followed the same plan but added turn signals to it. This is the template used but it needs to be resized to 1980px X 540px at 360px/in. (which is 5 1/2 x 1 1/2 in.) to fit into the Blast light.  You should be able to just print it and it should fit right in the fixture.  I used the template to cut the shape out of acrylic. Then taped the template onto it so I could drill the holes for the led's. NOTE: I drilled more holes than the template showed because of the extra yellow led's. Shown later.  Led's have + and - leads, usually the + lead is longer. Notice once you start installing the led's you must make sure the leads are facing the same way so that they are connected in series NOT parallel. Now get ready for ALOT of soldering.  This is how it fits into the lens. Notice that if I had planned better, the leds would have fallen deeper into the lens making the light brighter through the lens.  You can put a couple of white leds pointing downward for the lic plate light. This is a test of resistors to see which was best.   I added yellow leds for turn signals, about 24 for each side. And since the brake light used 150ohm resistors on 45 red led's, I cut the figure in half and used 75ohm resistors on each side. I didnt bother with the blinker timer because I like the faster blinking. All I had to do was connect the positive side of the turn signal to the positive side of the yellow led's and it worked like a champ.  The site listed above shows how to make the connector out of a 1157 light bulb.  Its a bit tricky but it works good. If I had to do it all over again I would have been more patient and ordered 30ma leds instead of buying the 20ma led that were on the shelf. I think it looks great but the red running light could be a little bit brighter. Not bad figuring that I saved about $100. | ||

Maybe some one can help I just bought a few led marker lights. The first set I put in the front (LP racing, Model #122-0001) worked fine blinked a little quick but work. The second set (LP Racing, Model #122-0041) rear mount on each side of the license plate really cool looking if I could get them to work. They just buzz and no blinkers work. If I put the OEM ones back on no problem. Any suggestions LP racing was no help. They claim I shouldn't need a relay.  | ||

Sorry to be a bit Ignorant, but what size of resistors would I need?  Or do I need one relay per light???? | ||

In my case I followed the design for resistors I found on the web page I put in my first post. Its worth reading. I was very brief in this discussion because of it. Ultimatly I used resistor values of 150ohms for 45 leds to be used as running lights, 17 ohms for the same 45 led's used as brake lights and 17 ohms for 24 yellow leds as blinker lights (1 resistor and 24 yellows for each side). It will depend on the LED's you use. Ill post the formula after I find it again. I ended up with 20ma led's instead of 30ma like the guy had on the site. But I used the same resistor values which worked fine. As far as the flasher module, you only need it if you want the lights to flash at the same rate (speed) as the bulbs. The LED's have less resistance causing the factory flasher to flash faster (say that three times fast). Its designed that way to alert you to a burnt bulb. Heres a video of mine "without" the flasher module. I like it flashing fast anyway. http://youtube.com/watch?v=WKQ6naJIO90 (Message edited by Buuueller on September 05, 2007) | ||

This is a great site to learn the basics about LED design: http://www.kpsec.freeuk.com/components/led.htm And this is the site that I based my design off: http://www.sca40.com/led/ | ||

I just got the relay and put the rear lights on they work great pretty bright too. Thank you for your help.  |
