Timloon Car Temperature Display Dual-Sensor Fahrenheit for Toyota — Internal & External, Blue/Red LED

Timloon Car Internal and External Temperature Display is a dual-sensor Fahrenheit gauge that shows cabin and outside temperatures on blue/red LED readouts for compatible Toyota models.

This compact gauge mounts into a 40.5 x 22 mm slot and provides continuous temperature feedback using two separate sensors — a long external probe and a shorter internal probe — powered by a 12V connection. Designed for a range of Toyota vehicles, the unit is built from fire-resistant ABS and delivers practical, at-a-glance temperature numbers in everyday driving situations. It is engineered for convenience, not lab-grade precision, so keep sensor placement and vehicle compatibility in mind before buying.

How does this display show both inside and outside temperatures?

The Timloon unit uses two dedicated sensors and dual-color LED readouts to present temperature for the cabin and the exterior simultaneously. The interior sensor connects to the red display; the exterior sensor connects to the blue display, allowing you to read both values at once.

• Dual-sensor design: external probe (116" / 295 cm) and internal probe (37" / 95 cm).
• Separate LED colors: blue for outside, red for inside.
• Fahrenheit range: -4°F to 158°F with graduated resolution.
• 12V operating voltage for standard vehicle electrical systems.

Will this unit fit my Toyota, and how do I verify compatibility?

Fit depends on your vehicle's available dash aperture; the display requires a mounting hole around 40.5 x 22 mm (1.57" x 0.86"). Although the product lists many compatible Toyota models, we recommend measuring your mounting slot before ordering to ensure a correct fit.

• Required mounting hole dimension: approximately 40.5 x 22 mm.
• Listed compatible models include Hilux, Prado 120, Land Cruiser 100, 4Runner, Tacoma and others.
• Check left/right position notes for models like Tacoma (2012–2014 left side only).
• Not universal; review dimensions and dash layout prior to purchase.

What are the measurement accuracy, range, and display behavior?

The gauge measures in Fahrenheit from -4°F to 158°F. It provides finer resolution near typical temperatures and coarser steps at higher ranges; values outside the supported range will show an error indicator. It is suitable for general driving use but not for laboratory-precision readings.

• Temperature range: -4°F to +158°F.
• Resolution: 0.1°F steps between 0–99°F, 1°F steps 100–158°F, and 0.1°F for small negative values.
• Displays an “E” for temperatures beyond the measuring range.
• Designed for practical vehicle monitoring, not precision scientific measurement.

How should I install and position the sensors for reliable readings?

Install the external sensor where it senses ambient outside air temperature without direct sun exposure or contact with metal surfaces. Do not cover the sensor tip with tape or place it near heat sources like air vents; secure both probes so they do not touch the vehicle body or road-facing surfaces.

• Do not cover the sensor with vinyl tape or adhesives.
• Avoid mounting the sensor in direct sunlight or near HVAC outlets.
• Keep the external probe tip away from metal contact and road surfaces.
• Handle the sensor tip gently — do not step on it or kink the cable.

Who is this unit for? This Timloon dual-temperature display suits Toyota owners who want a simple, visual way to monitor both cabin and exterior temperatures while driving. It is ideal for drivers who frequently need quick temperature awareness — for example, those checking road conditions in changing climates, monitoring cabin comfort during long trips, or fitting a compact aftermarket gauge into older Toyota dash spaces. If you require laboratory-level accuracy or your vehicle lacks the specified mounting slot, consider measuring carefully or choosing another product designed for your exact requirements.
