geth --syncmode light

What is wrong with my light client?
Light sync relies on full nodes that serve data to light clients. Historically, this has been hampered by the fact that 
serving light clients was turned off by default in geth full nodes and few nodes chose to turn it on. Therefore, light 
nodes often struggled to find peers. Since Ethereum switched to proof-of-stake, Geth light clients have stopped working altogether. Light clients for proof-of-stake Ethereum are expected to be implemented soon!
