yes light have momentum
Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely "no": the photon is a massless particle. According to theory it has energy andmomentum but no mass, and this is confirmed by experiment to within strict limits.

The short answer is "no", but it is a qualified "no" because there are odd ways of interpreting the question which could justify the answer "yes".
