About this part
Side mirrors on your #3 HX21 are essential for safe driving, parking and lane changes. A broken mirror from a collision, vandalism or parking mishap needs prompt replacement for safety.
Frequently asked questions
On the Smart #3, can I replace just the mirror glass or do I need the whole unit?
On most vehicles the glass can be replaced separately – it clips or glues onto the backing plate. If the housing, motor or electronics on your #3 HX21 are damaged, the complete unit is needed.
What features should I check when ordering a side mirror?
Side mirrors vary by trim – check for heating, electric folding, blind spot indicators and integrated turn signals. Order the correct side (left/right) and match your vehicle's feature set.
