Alright so I decided to finally change my interior lights to red. I haven't done the gauges yet but I have a problem with the HVAC lights. So, I unscrewed the HVAC bulbs(there are 2) and I slipped on 1 red light bulb cover on each. They were perfectly fine until the next day when I noticed they were orange, so then I figured that the covers must of slipped off. Well, the next day I unscrew both and I put on 2 new bulb covers on both and it seemed like it was fine until yesterday when they were orange. So, I am wondering if I am doing anything wrong, or if there is something I can do to keep the bulb covers on the bulbs?
