UFO Sighting in Ferndale, Washington on June 6th 2015 – 6 to 8 glowing orange lights traveling south

I'm a Canadian truck driver and was heading north on I-5 on June 6 th 2015 near the town of Ferndale Washington when I notice 6 to 8 round orange lights traveling in a dual V style shape heading south towards Bellingham Washington. They were traveling at a constant speed with equal distance between them about 800 to 900 feet above ground. The speed they were traveling was most likely around 60 to 80 mph. The objects were a solid light. Didn t hear any sound but that was most likely because I was in my truck. Lost sight of them as I was heading north and they were heading south.. Ian
