A member of the Facebook group "Mars Emergency Lights" posted this and I have received permission to share it with you all. "He is still offering replacement domes for the Mars Aurora Borealis Light." The poster thought they were around $300. CONTACT THE SELLER VIA THE PHONE NUMBER IN THE FLYER. I do not believe that the seller is currently a member on here. I am not the seller. I have never met the seller. I can not guarantee anything. I am not sure if the price listed is accurate. Yada yada insert every possible disclaimer here.
