The photo is blurry, but a capacitor does not make any sense in that circuit...
It is most likely a diode used to protect the LEDs from reverse polarity.
Those piranha LEDs usually have about 10v reverse polarity tolerance.
You can buy a 1N4004 diode at RadioShack for under 25cents, it has 400v reverse voltage and 1A forward current which should be enough to drive the 5 LEDs.
If you cannot read the color bands in the current limiting resistor, just put a meter to the one on the good light (make sure it is unplugged from anything else). Just buy the standard size closest to the resistance reading from the meter (likely under 300ohms).
