Thread: 12 Volts threw me, LED help!

lol well I thought I would try and hook up one of my LEDS to a normal 12 V car battery, to my shocking yet still num arm it lit for a milli secound LOL, I need to know what kinda resistor I need to use with my car battery to use these leds so they wont blow up!

Also could I hook them up to the accorriers fuse? so that when the car key is turned on the leds will also come on... if this wont work I would like to hook it up to the computer power but would kinda like less wires comming off of that

basic info about my LEDS:
Features:
Well Defined Spatial Radiation Patterns
Viewing Angle: 25 degrees
High Luminous Output
Color: Red (626nm)
High Operating Temperature: TJLED = +130 degrees C
Superior Resistance to Moisture
T-1 3/4 (5mm) package
Max Intensity (mcd): 234
Forward Voltage at 20mA: 1.5 Min, 1.9 Typ, 2.6 Max

So what kinda resistor do I need? thanks for your time!
