1. An optical system comprising:
a light conduit comprising:
a first light pipe having a first inlet to receive a first input light signal and a first outlet to emit at least a portion of the first input light signal to form a first output light signal;
a second light pipe having a second inlet to receive a second input light signal and a second outlet to emit at least a portion of the second input light signal to form a second output light signal;
a first bridge to mechanically couple the first light pipe to the second light pipe, the first bridge having a first end mechanically coupled to the first light pipe and a second end mechanically coupled to the second light pipe; and
a side arm mechanically coupled to the second light pipe, the side arm mechanically coupling the second light pipe to a substrate.
