Light, in the theory you’re indirectly referencing, is a disturbance in the electromagnetic field, not the field itself.
The fields are charged, hence all the formulas involving them reflecting charge in one form or another (charge density is pretty common); the amplitude of the field is defined as the force exerted on positively charged matter in the field. (The reason for this definition is that most electromagnetic fields we interact with are negatively charged, or have negative charge density, on account of electrons being more easily manipulated than cations, protons, plasma, or antimatter.)
With some creative use of relativity you can render the charge irrelevant for the purposes of (a carefully chosen) calculation. This is not the same as the charge not existing, however.
You are using charge in some non-standard way. Charges are source or sinks of the field.
An electromagnetic field does not sink or source more field- if it did, Maxwell’s equations would be non-linear. There is no such thing as a ‘negatively charged electromagnetic field’- there are just electromagnetic fields. Now, the electromagnetic field can have a negative (or positive) amplitude but this is not the same as saying its negatively charged.
