Yes, lighting behind a mirror can create a soft halo on the wall. The best approach depends on the existing mirror’s construction, rear clearance and location. For a bathroom refresh, a purpose-built backlit mirror brings the lighting and mirror together in one design, with controls and other features selected for the product.
Decide what you want the light to do first. A wall glow adds atmosphere and defines the mirror’s outline; light directed towards your reflection is more useful for close grooming. The right choice can make your vanity feel more inviting without expecting backlighting to do every lighting job.
A wall halo and face lighting serve different purposes
Backlighting shines behind the glass and onto the wall. Pale, matt surfaces often show the glow differently from dark or textured finishes. The room photograph is useful for style inspiration, but your wall colour and the intended mounting gap will affect the result.
If makeup, shaving or skincare is the priority, compare front lighting or a design combining front and rear illumination. Keep the room’s general lighting in the plan too: a decorative halo is not a guarantee of shadow-free task lighting throughout the bathroom.
Can you add a strip to the mirror you already own?
A retrofit needs more than a strip that fits around the edge. The mounting arrangement must provide suitable clearance, the lighting must be compatible with its supply and controls, and the finished installation must suit the bathroom location. Do not drill, cut or open an illuminated mirror to add lights without a manufacturer-approved plan.
For an unlit mirror, discuss the complete proposed assembly with the installer before buying parts. Keep access, support and servicing in mind. A separately rated strip does not by itself establish the suitability of the finished mirror assembly. Avoid running an extension lead into the bathroom to power a decorative lighting kit.
Three ready-made ways to get the effect
50 × 70 cm rectangular backlit mirror — £99. A clean outline and rear illumination suit a calm, uncluttered vanity. Touch control and anti-fog add everyday convenience to the softer wall glow.
60 cm HaloGlow backlit mirror — £139. The circular shape softens a tiled wall, with three light colours, dimming and anti-fog. Choose the diameter around the basin and nearby fittings rather than copying the proportions of a showroom photograph.
60 × 80 cm dual-light mirror — £129. Combine a wall glow with front illumination when you want both atmosphere and a brighter mirror area. Dimming lets you change the feel without changing the mirror.

Plan the upgrade around your existing bathroom
Mark the outside dimensions on the wall, check tap and shelf clearance, and decide where you want the controls to sit. Use the supplied mounting system and rear spacing rather than pressing a backlit design flush against the wall. Have the electrical connection planned before finishing tiles or decoration.
Our bathroom mirror replacement guide covers the changeover, while connecting an LED bathroom mirror explains the supply decisions to discuss with your electrician.
Choose useful extras without losing the main purpose
Three light colours can help you move between a warmer evening mood and a cooler daytime feel. A demister supports a clearer heated area after a shower, and memory can save a preferred lighting setting. Check the product’s actual controls rather than assuming every illuminated mirror works the same way. Our LED mirror feature guide helps you compare.
For twin basins, balance the width and placement across both users; see LED mirrors for double vanities. Browse backlit bathroom mirrors for a soft halo, or dual-light mirrors for both effects in one design.
