Abstract
The models with free vector fields are analyzed on the light-front (LF) hypersur-face. The massive vector model - Proca model - can be quantized unambiguously within the novel LF procedure, though it leads to singular terms in x+ coordinate. Also the modified models, where the Lorentz condition and the LC gauge conditions are explicitly induced by the Lagrange multipliers. Possible massless limits are studied for all cases and modes are classified as either physical or nonphysical.
