Avoid tricky blind spots when passing or changing lanes with CIPAs 3" round convex HotSpot mirror. Easily mounts to original factory mirror featuring convenient stick-on mounting. HotSpot mirrors may be placed anywhere you wish but are typically placed on the bottom outside corner of the original mirror. The desired placement varies from person to person. To find the placement that is right for you, start by placing a piece of folded tape on the back of the HotSpot and sticking it onto your OE mirror where you think you might want it. Then sit in your car and look through the HotSpot. Keep adjusting the placement until it suits your needs. Finally, remove the folded tape, peel the adhesive backing tape off the HotSpot and apply it permanently. Expand your Horizons
