Here’s a detailed description of a left-hand (LH) side mirror (''wing mirror'', ''door mirror'') for a Volkswagen Polo 1.6. If you tell me the exact model year or trim (e.g. ''H spec'') I can get more precise, but here’s a general breakdown of features + things to check:

Key Features

1. Mounting side
   
• LH means the left-hand side, which (in right-hand drive cars) is the nearside/mirror next to the driver.
2. 
   
3. Adjustment
   
• Can be manual, but often for Polo 1.6 (higher trims) it is electric adjustment.
• Might include motors to adjust tilt & angle via switch inside.
4. 
   
5. Glass
   
• May have heated glass (for defogging/defrosting).
• Could be convex or aspherical, depending on whether it’s driver side or passenger side; LH tends to use aspherical or convex to reduce blind spots.
6. 
   
7. Folding / Retractable Feature
   
• Some models have mirrors that fold in (manually or electrically) to avoid damage when parked.
8. 
   
9. Indicator / Turn Signal
   
• LH mirror might have integrated turn signal/indicator light (sometimes LED).
10. 
    
11. Colour / Finish
    
• Painted in body colour, or in basic black/plastic depending on trim.
• Sometimes comes primed (ready to paint).
12. 
    
13. Wiring / Connectors
    
• For electric mirrors, heated mirrors, indicators: there will be wiring harness/connectors.
• Check the number of pins (the more features, the more pins).
14. 
    
15. OEM Part Number
    
• For VW Polo, some genuine parts are labeled e.g. 6RG857507M9B9 for manual LH mirror (without glass & cover) in Polo/Vento.  
• For LH mirror glass etc, other parts will have their own OEM numbers.
16. 
    
17. Dimensions & Shape
    
• Must physically fit: correct mirror housing shape, mount bolt holes, angle of glass.
• For aerodynamics and water deflection, shape matters.
18. 
    

What ''H Spec'' Might Imply

Since you said ''H spec'', that might imply a higher trim level. Some implications:

• Likely electric adjustment rather than manual.
• Possibly heated glass.
• Possibly with a built-in turn-signal / LED indicator.
• Might have power-folding capability.
• Better finish (painted instead of black plastic).

If you want, I can look up the exact spec for Volkswagen Polo 1.6 H spec in Malaysia (or your region) so you get exact OEM mirror specs (part number, features). Do you want me to fetch that?
