A&L Horn Swap

[Bob Bidonde]

I have a like-new A&L 6-volt Sparton Horn, but my car has a 12-volt system. I want to trade my 6-volt horn for a 12-volt A&L horn.

You should try the Swap Meet section! Wayne

You might want to call Allan or Bob at A & L and ask if they can convert the 6 to 12! Wayne

I think all you need is a resister in line with the horn to drop the voltage to 6V. I am sure Tom W. can give you the correct value and wattage. I have never done it before, but I know it will work. That would be easier than trying to find a person to swap with.

Bratton's has the resistor that fits inside the horn. Part # 20050 Bert's has one that mounts on the frame rail #A-1320-B

Instead of swaping the horn try buying a step down transformer 12VDC to 6VDC for $12.99 on Ebay (DC/DC Power Converter Regulator Module Step Down Adapter 12V/24V to 6V 5A). Maybe some EE can chime in with a simple wiring diagram that uses a 7805 voltage regulator with a diode or two. The horn usually only gets pulsed and doesn't operate continuous.

A&L must have built the new Sparton horn I got from Bert's several years ago.....it is darn near perfect and sounds GREAT!!!! Hard to tell from an original! Kept my original it's in a box in the garage.

A transformer is more efficient to drop the voltage, but a resistor is smaller and easier to install. Like CT Jack states, you only use the horn very, very intermittently, so efficiency is not a problem in my opinion.

I have the A&L 12V horn. Looks & works perfectly.
