If you're familiar with the crunching sound of bikes, kayaks or other gear strapped to the roof of your car as you absentmindedly pull into a garage, you'll appreciate this HeadsUp sensor system that will stop such catastrophes from happening again.
The starter kit includes a couple of waterproof sensors that strap to your roof-mounted gear, an in-car audible alarm and an LED visual alert sign to hang on the back wall of your garage. The next time you pull into your driveway and open the garage door, the sensors on your gear will detect a signal emitted from the LED sign and will trigger both the audible alarm and the flashing LEDs. And at least one of them should remind you there's stuff on your roof well before you get near the entrance to your garage. Think of it as $US170 worth of insurance that's going to protect your gear from your own forgetfulness. [HeadsUp Systems via Gear Junkie]
