My family and i were travelling on highway 97 just outside of westwold nearing monte lake. we were travelling a bit faster than we should have and i first had thought we were being pulled over but soon realized it was not what we expected. i had slowed down to around 50 kph pretty quick as i figured i was going to get pulled over but all of us in the vehicle observed what seemed to be like very slow pulsating red, blue and orange lights that almost dulled themselves down to a low beam to a bright light. we observed what seemed to be a dark objet near the passenger front section of visible window area. we had the speakers in our vehicle make a awful screeching noise and weird vocals that were not like anything i have ever heard. i then slowed right down to almost a rolling stop on the highway and our electrical in the vehicle started doing the funky chicken and what seemed to be like shorting out. i wanted to pull over and get out or at least pull a u turn and investigate but with screaming kids and them begging me to keep driving, felt it was best to continue.
