I have hearing impairment. Which Honeywell doorbells provide visual alerts?

All Honeywell Home Doorbells (with the exception of DC311xx and DCR311xx) have visual alert features including a bright LED strobe effect light for the hard of hearing.

For Series 3 (DC315xx and DCR315xx), Series 5 and Series 9 Doorbells, they also have a multi-colour halo light feature that is able to assist the user to visually distinguish between different activations.
