Reduce intrusive light, but keep air circulation. Spring loaded Lights Outô Vent Shade blocks moonlight or street lights from your RVís sleeping area. Space efficient housing is easily installed with included mounting hardware. Lightweight, durable vinyl with reflective finish, which also helps to block heat.
For $8.99 I thought I'd give it a try. In my new rig, one vent is over the bed. It's kind of bright if you want to sleep past sunrise. This should help.
