An AC adapter charges an Information Handling System (IHS) and includes a first DC plug including a DC connector that is compatible with an IHS power port. The first DC plug includes a first light guide for receiving light transmitted from the IHS and for illuminating an indicator of the first DC plug. The first DC plug comprises a fiber optic wire that receives the light received by the first light guide and illuminates the indicator. The fiber optic wire may extend within the DC cord and may illuminate an indicator of a second DC plug on the opposite end of the cord. The DC cord may include indicators illuminated by the fiber optic wire extending within the cord. The fiber optic wire terminates at a light guide of the second DC plug and exits the light guide of the second DC plug when the second DC plug is uncoupled.
