We’re not telling you to install a backup alarm, throw your vehicle into reverse and “damn the torpedoes.” But a backup alarm can help avoid accidents by alerting others that you’re about to back up. Backup alarms come in two styles: as a replacement bulb for your existing backup lights and as a freestanding alarm to mount under your vehicle.
The bulb alarm isn’t as loud as a freestanding alarm because the bulb sits inside your light assembly. Choose from two bulb styles: The Hopkins No. 20100VA (about $20) replaces a No. 1156 bulb; the No. 20101VA (about $20) replaces a No. 3156 bulb. If you want a freestanding alarm, try the Wolo BA-52 (about $10). Want to sound like a garbage truck? Buy the heavy-duty, extra-loud BA-107 (about $24) for 107 dB of beep-beep.
Install a Beeper Bulb:
Remove the backup light socket and snap in the beeper bulb. Wipe off any fingerprints before you reinstall the socket.
