1. An apparatus, comprising:
- a light module, comprising;
a first light emitting diode having a first set of electrical characteristics; and
a second light emitting diode connected to said first light emitting diode in parallel such that said first light emitting diode and said second light emitting diode have the same polarity, said second light emitting diode having a second set of electrical characteristics that are different from said first set of electrical characteristics, such that said first light emitting diode carries substantially all of the current that is conducted through said light module, while said second light emitting diode remains unused until said first light emitting diode fails to conduct said current.

Abstract
A lighting module with improved reliability including a pair of LEDs connected in parallel and with the same polarity and a method for making the said light module are disclosed. The parallel LEDs with the same polarity will increase the reliability of the light module and make it suitable for use in light strings where a relatively large number of such light modules are connected in series and where the failure of one such light module will cause the failure of the entire light string. A light string made of such light modules and a method for making the light string are also disclosed.
