There is provided an optical system comprising a light conduit. The light conduit comprises a first light pipe, a second light pipe, and a first bridge to mechanically couple the first light pipe to the second light pipe. The first light pipe has 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. Moreover, the second light pipe has 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. Furthermore, the first bridge has a first end mechanically coupled to the first light pipe and a second end mechanically coupled to the second light pipe.
