1. A composite structure comprising:
a structural composite including a plurality of reinforcing fibers encapsulated in a first polymer resin, the structural composite including a polymer substrate, and the plurality of reinforcing fibers attached by thread to the polymer substrate;
M sets of traces arranged on the structural composite;
N sets of microLEDs arranged on the structural composite and connected to the M sets of traces, respectively, where M and N are integers greater than zero; and
one or more cables connected to the M sets of traces,
wherein the structural composite, the M sets of traces, the N sets of microLEDs, a portion of the one or more cables are encapsulated in a second polymer resin, and
wherein the second polymer resin includes an integrated lens adjacent to the N sets of microLEDs.
