SYMTEC ATV/SNOWMOBILE HEATED HANDWARMERS, Manufacturer: SYMTEC, Manufacturer Part Number: 210007-AD, Stock Photo - Actua

I've bought perhaps half a dozen of these over as many years, to retrofit into older cars that did not come with heated outside mirrors.Regardless of the pic shown below, you'll probably need two per mirror, to get full coverage and to work well below freezing temps.I've also dropped them into the ducts that blow onto the windshield, for an early boost to the defrost.

Excellent delivery, easy installation, and work like a dream. Very happy with the product and the price.
