28404, hooking up LED's...
Posted by phatGS, Aug-07-02 04:59 PM
Is there anything special to take into consideration when hooking up LED's if I wanted them to come on with parking lights?? or is it just power and a ground?

You'll need a ressitor otherwise you'll burn it out. Most LED are rated for about 5V.
To figure out what resistor you need use this formula:
(Vcar-Vled)/Aled = R
Vcar is the Voltage of the car, assume 14V to me on the safe side.
Vled is the Voltage the led is rated to (you'll find it on the package)
Aled is the amp rating in Amps of the LED (also on the package and remmember 1mA =.001A)
R is the resistor you'll need in Ohms. You won't find a perfect match so use the resistor that's closest.
Keep in mind that the bigger the resistor the dimmer the LED will be, but you use to small of a resistor you could burn it out.

I use 330 ohm usually.

330 ohms will probably work, but not all LEDs have the same ratings.

what ^ said is right tho. I used ordinary Radio Shack Led.

where's the resistor go... power or ground side?

according to hondahater, it shd weld on poistive side(the longer wire)
