About

CANNY.LZR

Read full description

Provides convenient and fast activation of your CANNY dongle, enabling your auxiliary vehicle lights to be switched on and off directly from the CAN signals of your vehicle, without the need for a separate switch to be installed in the cabin. CANNY.LZR app also enables you to activate your auxiliary lights directly from your phone (only when combined with fitment of the CANNY dongle to your vehicle), speeding up the installation process of fitting additional lights to your vehicle, and giving you options to control your extra lighting at any time, independent of the vehicle CAN signals. The CANNY dongle is a waterproof device which can be placed either in the engine bay or inside the vehicle cabin, making it faster to install than alternative CAN readers. Please check www.lazerlamps.com/canny-vehicles for a full list of vehicles for which the CANNY dongle is compatible. At Lazer Lamps Ltd (Triple-R Lights in the USA), we are prioritizing developing the vehicle recipes (i.e. interpreting the vehicle CAN signals) for vehicles which don’t have a 12V high beam feed at the back of the headlight (i.e. cars with LED headlights, matrix, and those with certain low beam / high beam projector modules). The list of vehicles is being updated on a weekly basis, so please do check back at regular intervals if your vehicle isn’t yet listed. For those vehicles listed on www.lazerlamps.com/canny-vehicles, a detailed wiring instruction is available for download via the CANNY.LZR app. Once the CANNY dongle has been purchased, scan the QR code on the devices, using the CANNY.LZR app, and you will be able to download detailed vehicle-specific wiring instructions, including CAN wire pickup locations. In the event that your vehicle has a 12V high beam feed at the back of the headlamp, then it isn’t necessary to purchase CANNY (or the related CANNY.LZR app) to activate your auxiliary lights. In those instances, it’s possible to splice a relay-trigger-wire directly to the high beam 12V feed, behind the vehicle headlamp. Please checkout our Youtube channel youtube.com/lazerlamps for details on how to check for a 12V high beam feed at the back of your headlights. The CANNY dongle features four outputs, allowing you to use different vehicle triggers (high beam, position light, low beam, reverse, ignition, indicators) to activate your extra lights. Generally, customers installing Lazer or Triple-R lights with both High Beam and also a Backlight / Position light function will want to use two of the CANNY outputs to activate those two functions of their auxiliary lights. Additionally, if extra lights have been fitted at the back of the vehicle to aid reversing, then a third output may be used from the CANNY dongle, being activated by engaging vehicle reverse. A single connection to the vehicle CAN wires is all that is required for the CANNY to interpret the vehicle CAN signals, and activate these three outputs simultaneous with the original vehicle lights being switched on/off. The fourth CANNY output may be used (for example) by customers fitting an additional light bar on the roof, where they want to activate the lamp via the CANNY App on their phone, as opposed to being switched from vehicle CAN signals. CANNY dongle features over-the-air updates via the CANNY.LZR app, to ensure that your device always contains the latest security and technology features. Lazer Lamps Ltd is a UK manufacturer of high performance lighting products, with warehousing in the UK and inside the EU; we offer technical support for all product purchases. Our USA subsidiary Triple-R Lights (HQ Arizona) is also able to provide support to customers in the USA, while customers in Australia will receive support from our local team, based Down Under!
