I was looking to buy these items on AliExpress but is not available there. However, it is possible to buy these on Taobao, which can also ship outside of China to most countries (price varies but is relatively cheap for NZ, AU, UK, US = about $5-20 USD)
Links for items on Taobao - not referral links
Ambient lighting = https://item.taobao.com/item.htm?ft=t&id=971864246471 (approximately $30 USD)
RGB screen for back window = https://item.taobao.com/item.htm?ft=t&id=963995667633
Around $100 USD with shipping for both items.
