A mobile device software app facilitates a user's identification of a product suitable for various vehicle types and operating environments. The app configures a sensor in the device to sample ambient sound or light in the vicinity of the vehicle, calculates an intensity level value for the sample, compares the value to a list of specification intensity values corresponding to vehicle accessory products, and generates a list of products having intensity values greater than that of the sampled sound or light. The app optionally provides for user selection of a product and for viewing product literature. Users can also access detailed technical installation information, listen to sound samples, and locate product vendors.

Techniques for communicating lighting commands through a controller area network (CAN) bus of a light bar system include generating a light code message. The light code message has a metadata portion and a value portion. The metadata portion defines a purpose of value portion. The value portion controls a state of a lighting device (e.g., a keypad's LED brightness or activation of a directional light module) in the light bar system. A data field is generated by encapsulating the light code message with an ISO-TP single frame header and a message subtype. A CAN controller generates a CAN message having an extended frame format and the data field. The CAN message is then transmitted through the CAN bus.
