A strobe can be an excellent defense, particularly an intense flashlight.
We had used strobes as an optical defense in the past, and they are incredibly disorienting. A bright flashlight with a 15-20 Hz strobe makes about 90% of the people have to look away, and causes seizures in about 5%. Most strobes are slower than this, but a few speciality units designed to grab attention use these frequencies.

DHS also had a high profile program few years ago but it was quietly shelved, possibly because of the potential for inducing epileptic seizures.

Good luck, have a safe trip.
