All About LED's

[IDontKnow]

Hmmm, somewhere back in this thread it was stated that each LED requires a resistor!
Not True! I have two flatbed trailers each with 10 clearance lights (5 each side) and only 1 resistor.
I have the infrared lighting system from SS-Tronix and the whole thing is powered by a 7.2v pack mounted between the rails. Power comes up from underneath feeds to a 1/2 watt resistor then loops in and out of each led in parralel down the left side and back up the right. Works beutifully using 3mm high brightness orange LED's in chrome bezels.
If I get a chance I will show some pictures of the setup.
