Wiper or Horn 12 volt to 6 volt Reducer - WHR1

This volt reducer is an essential vintage car part when converting from 6 volt to 12 volt electric. In order to keep your stock 6 volt accessories functioning and protect them from burnout, this reducer dampens power running to windshield wipers and horns.

The voltage reducer provides 40 watts of power which is enough to run wipers and horns on most vehicle models. When ordering, keep in mind that each accessory will need its own voltage reducer.

With its small size, you can place this voltage reducer wherever you need to in your car, although it is generally recommended to install it on a metal surface with adequate surrounding space for air circulation for cooling. We also recommend using the reducer with a 15 amp fuse.
