Buying Guide: Key Purchase Considerations

  • Power option and runtime: Decide between 12V direct-power signs and USB-rechargeable units. USB models offer flexibility and longer life, while 12V signs are straightforward for fleets with existing power hookups.
  • Mounting and durability: Magnetic bases allow quick swapping, but assess the roof material and road conditions. Waterproof and sun-proof designs help in harsh climates and long-term use.
  • Brightness and color options: Look for signs with clearly visible LEDs in daytime and nighttime conditions. Some models offer multiple colors to denote different services or statuses.
  • Text customization: Blank taxi signs with letter stickers enable on-the-fly text changes, useful for dynamic dispatch or special events.
  • Safety and compliance: Ensure the sign adheres securely to the roof and does not obstruct mirrors or sensors. Fast lighting response reduces rear-end collision risk.
  • Installation effort: Evaluate whether the sign needs professional installation or a simple plug-in setup via cigarette lighter. Simpler installs reduce downtime for fleets.
  • Maintenance and replacement parts: Consider availability of replacement magnets, cables, and LED modules. Durable seals and easy access to power connectors extend life.
  • Size and visibility: Check dimensions to balance conspicuity with aerodynamics. Larger signs tend to be more visible but may affect roof weight and handling.
