Optimal optical wireless transceivers are needed to facilitate the implementation of massive LiFi in Intelligent Transportation Systems operated by 6Gs and with vehicles communicating intensive high rate and low latency data through the strictest power requirements. This paper explores three transceiver designs that are optimal to vehicular LiFi connections: a default IM/DD design, an energy-optimal OFDM architecture using adaptive power loading, and a MIMO-optimal design using spatial diversity as a source of spectral efficiency. A system model that combines optical channel characteristics, hardware power and ITS latency requirements is created and used to check the energy-per-bit, through put and delay performance. The results compared illustrate that the energy conscious transceiver of the energy-conscious of the OFDM harners much less energy use in medium-throughput situations compared to other energy-conscious schemes, and that the transceiver optimized by the MIMO delivers lowest energy-perbit at the higher-data rates. These results suggest the possibility of using LiFi in 6G vehicular networks, and combination of LiFi and 6G rays makes it possible to have sustainable and highcapacity V2X connectivity. The paper also presents deployment considerations and hardware design principles in the real world ITS implementation.
