The Shoebox Electronix Battery Saver is the best headlight alarm available for 1984-1991 VW Vanagons. It is an independent and dedicated electronic device that can be installed easily, and later removed and wired into a different Vanagon if needed. This is an entirely more reliable and specific method compared to simply modifying your existing door buzzer, as it generates a different sound than the stock buzzer circuit.

 

In addition, the Battery Saver will automatically end its alarm in approximately 10 seconds, if for any reason you WANT to leave your headlights on temporarily. While the price has remained the same since 2006, the alarm itself has been upgraded with a new printed circuit board (with a smaller footprint), a more efficient heat sink, and an
improved louder sound module.

Not subject to discount.
