TrackLight is an LED trailer light that looks and functions like a standard light, but has a GPS tracker inside. It's available in different forms, including a 4" round tail light, 6" oval side marker light, or 4" square combo light. With an IP67 rating, it's waterproof and shockproof, making it ideal for harsh road conditions. The built-in Lithium-Ion battery can provide up to 90 days of location reporting without charge, and it's easy to install by replacing one of your existing lights.
