When my electronic alarm clock stopped working at some point in 2019 I didn't go to Argos or search Amazon for a suitable replacement. No, that would of been way too easy and saved me loads of time. Instead I decided to buy a kit from eBay and make my own! The kit uses large LED's that are easily viewable from across the room at night. Other features are an alarm, temperature reading, the day / date as well as auto dim / brightness. The RTC uses a button cell to keep the time settings whilst the LED display uses 5 Volts from a USB mains phone charger.
