I need a flashing wireless doorbell

My dad refuses to address his hearing problem, and I’m looking for a wireless doorbell that gives off a good flash as it dings. I keep finding ones that sort of glow, etc, but I need it to have at least 4 receivers and flash so you’ll notice even if you’re turned away from it. Amazon and Newegg are being little help.

Anyone got a recommendation?

This site specializes in aids for the hearing impaired. It looks like it has some options that might work.
