Side mirror is more than just plain accessories in your vehicles. They faithfully serve for safety reasons in driving. These mirrors give a full and clear picture of the objects that come behind or beside the car you are driving regardless of the distance they keep away from your rear or side. Signal side mirror come in pairs which are positioned outside of the car. A red chevron lights up when the driver activates his turn signals and these signal side mirror alert the drivers of up to three vehicles behind you of your course of plans to act out. Meanwhile, towing mirrors are called "slip-ons" into the vehicle's existing mirrors which provide better visibility for safe towing. Too much bright lights likewise enable the automatic dimming rearview mirrors to shift into "night mode".
