Re: Grand Cherokee Brake Shudder Fix (I think)
DougW,
question: If you use a 5v voltage regulator, why do you need the 200 ohm resistors? I dont get it. I've hooked up LED's using only 1K ohm resistors and they worked fine. Are the resistors necessary?

Without them the LEDs would burn very brightly for a second then become a SED (Smoke Emitting Diode). :) Actually you can drop using the regulator and just size the resistors for 14V. But since the voltage is hard to predict I dropped in a regulator. That means that even if the battery is a bit low, or a bit high, The signals will always be the same brightness. The cheaper LEDs you see for cars either have a regulator in them or more commonly a limiting resistor. When shopping for LEDs you are looking for the brightness (mcd) and viewing angle. The hardest part was figuring out the viewing angle so that motorist could see the signals. Still not sure I got it right. This site has some useful info and calculators. http://www.theledlight.com/technical.html -- DougW |
