The resistors are current limiters for the LEDs. 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.

Re: Grand Cherokee Brake Shudder Fix (I think)
 

I went to Advance Auto, bought some Bendix higher end pads and Raybestos
rotor for a lot less then cross drilled Stillen parts I am sure. They have
been on the vehicle for 4-5 years and probably 70-80k miles or more. No
brake issues. Before that the car would not go more than 10k mile without
brake shudder. It is apparent to me that the DC stuff was just plain JUNK>

Re: Grand Cherokee Brake Shudder Fix (I think)
 

Chrysler put their "heavy duty" rotor and pads on our '99 and they still
warped. They turned them once more for free and said that was it. no more
free brake work.

Sorry, Daimler didn't really fix the problem until half way thru '02
when they replaced the Teves calipers with Akebono and their bracket, silver
in color, as pictured: http://www.----------.com/temp/WJCaliper.jpg Write
