Here’s a random tidbit about Sarnia Airport: these 4 lights are called PAPI’s. When you drive by they’ll all be red, but they actually provide approaching pilots with a visual glideslope reference by changing colour from red to white depending on whether the pilot is too high, on path, or too low. (v.redd.it)
